GAD F-6 Lightning Kit Release 1-6-06

[mjblack]

Hi All,

Just wanted to get your feeling on our new kit.

As most of you will know GAD had to close for a while, personal reasons, divorce, house buying that sorta thing. But were back, new laser cutting machines, new kits and hopefully a whole new world RC fun.

This is our prototype EE F-6 Lightning, It is kitted and in boxes just trying to finalise the manual (hence pic include no canopy and frills) but shes flies like its on rails. Very easy to build and quick.

Please post your thoughts.

Regards,

Mike.

[mjblack]

hi again,

Something I meant to meant to mention before is that there will be 2 kits up for grabs as promo kits for poeple to build and log perhaps on here to let others know how they got on and help us with refinements.

If anyone is interested please let me know.

Regards,

Mike.

Mike
welcome back. Kit looks good, I would definitely be interested in one. What are the dimensions?

I am currently finishing one of your F14s. http://www.rcgroups.com/forums/showthread.php?t=369511

I like your kits and am happy to see that your back.

Mike

[dusmmdb34]

already picked out a paint scheme

[jzanutto]

Hi Mike,
count me in if no one else beat me to it. This will be a good way for me to get into the depron jets, and for you to gather some data on a brushless outrunner power system. I'm the same guy who has been talking to you about power options on the SU27 flanker.

[mjblack]

hi, guys,

Yeah i read through your thread of the F-14, outstanding, Your sooooo close to maiden....as long as your throws are right (wings in wings out aileron) and of touch of up for her first launch it should be great!

Im now making another one as well....mines seen 2 years service and looks a little battered now!......lol....wings are great so i might just make another fuse for it.

You guys are on2 F-6`s coming up! you have a shioce you can have them as they are with just drawings to build from or wait fro me to finish the manual. Your call.

nice scheme by the way, that deff teh way i would go.

JZ, like wise friend, but be aware that the F-6 deos require more power than the su fro launching, i dont know why but she needs a hoof to get away, once in the air it is very docile and prodictable...you can fly are stupidly low speeds with out stall, but just needs a good launch, One other thing....launch at 2/3rd to 3/4 throttle.....seams to be the best.

I have your pm`s so wil reply.

oh well, tell you guys what......as a celebration of being back ill throw in a 3rd kit if anyone wants a play, same rules apply....lol...

regards,

Mike.

[killickb]

Yesterday I sent you an e-mail for kit availability in the US but will gladly pre-pro the third kit for you, will mate my other Mega powered F-6 pusher -- Hawker Hunter.

[The Captain]

Hi Guys

I'm very pleased to have been invited to be part of the new GAD team :cool:

Got my f6 on monday and already done most of the fuz and the wings - goes together really well :)

Need to sort the pics out then i'll do a build thread

best wishes

Nick

[dusmmdb34]

Thanks Mike,

I will pick a power system this weekend.

Mike

[Andy McCowan]

Nice to see that you are back Mike, model looks cool even without the canopy. :)

[Littlescreamers]

I think I could come up with a good motor for this plane, What is the AUW of this nice bird?

Scott

[mjblack]

Hi guys,

Andy, nice to hear from you again, how have you been? stillflying?....life treating you well? ERm...no canopy...couldnt be bothered just to test the airframe, we do have mouldings fro the F-6 the kit is complete, but i see no point in frills when testing...drop me a line sometime to catch up.

Scott,

This sounds interesting, AUW of around 15oz, remarkably low weight for a 26" span byt 40" long. this is including batts and motor as is, with a drop of paint it going to be under 18oz with all frills and niceties on board. Please drop me a line perhaps we can do double promo, I will also be looking for a good motor fro our ne F4 Phantom when its goies up....its half built similar weight but a bigger wing area than the f-6 so maybe we could jion forces and see hat happens?

I look forard to your reply.

regards,

Mike.

P.S........Nick , you built that yet?....LOL.......let me know and well get together fro teh maiden!....

[mjblack]

Hi all, just a quick word.....guess what 2 idiots standing in a field, in the pooring rain adn gales were trying to test yesterday?...... :p


Can you guess what it is yet?

Best regards,

Mike.

[dusmmdb34]

Can you say F104.................... what am I doing still awake????

[mjblack]

HI, if you guys hang on five mins im now uploading some vids for your perusal, these are protos so not edited, just filmed and shown.

See what you guys think.

regards,

Mike.

[dusmmdb34]

from the pics, it looks really good. I don't know of anyone making a inexpensive F104 kit, it should be a good seller. Might have to make it a edf

Mike....you have been busy

[mjblack]

Oh yes friend, between the guys and myself , weve prob been doing 18 hour days, well this is a last ditch attempt, we had a good business, goot reputation adn very good kits, but my personal circumstances prevented me from doing, adn my then business partner did not take care of things so we upset a few poeple, including randy from dynamo, who is a wonderful gentleman not only in his work but his care fro this sport and its users.

Thankfully i do have a wonderful guy who now ships all our stuff to the US and thanks to him the door is still open in the US. I have found that parkflying jets are very popular but a very large proportion prefer that "REAL JET FEEL" and GAD is the only way to go as far as we can, we started the depron aircraft craze and were trying to take it beyond the envelope again.

Starfighter.....flies very well.....as long as you do NOT slow it up, there is almost a none existent glide, but its had 5 flights now, wether we kit it depends on the interest from you guys realy......but its NO beginner plane, with scale wings, Anhedral, its challanging to fly, but very vbery good fun. If anyone wants one please drop me a line and we will talk about it.

Oh...and like all our kits they are all rock bottom price somewhere around £45 for this kit....but its not in a run so these would be one offs for those brave souls who like a challange.

regards,

Mike.

[The Captain]

P.S........Nick , you built that yet?....LOL.......let me know and well get together fro teh maiden!....

I'm doing me best - just sent out for bulk order of batteries for digicam and sand paper seeing as me mate with the car body business has moved away so cant steal his DA disks anymore :rolleyes:

Should be on schedule for next weekend unless i'm real busy this week :cool:

Oh and erm - yes i want a Starfighter - like NOW :eek: :D

[Andy McCowan]

Mike,

Yes I am still flying, must be some kind of disease as I can not give it up! ;)

Your new designs look to be very good, I especially like the F104, now there is a challenge to fly. What motors are you running in the new models?

Keep up the good work! :)

[mjblack]

Hi,

Good to know your still at it mate, yeah i think there is somthing in this flying desease thing!...lol

Motors, fro simple testing i have use the SF-2500 very similar to the align 400, but today we flew teh F-6 with a 4t mega, much faster!....lol :D

Its blowing a 40 knot wind here! :eek: but thought we would have a go anyway..performed well.....landing was a bit hairy but no issues the glide is totaly predicable. But the weather here is a little rude realy for testingplanes!

F-104.....erm..yeah challenging.......scale wings and anhedral, at speed shes fine, no glide though, but easy enough once flying. Not sure wether to kit it or not.....its no beginers model......flying is just like any other unstable plane...easy at speed.....but landing is downright hairy...but as you say .....it is a starfighter!....lol...if any of you guys fancy a challenge, drop me a line and well se what we can do. BEWARE ITS NOT FOR ANYONE LESS THAN VERY EXPERIENCED! Sorry, dont want to get anyones hopes up that its easy at low speeds...

if you like please pop to our site adn check out the videos for the F-6, F-104, lancaster adn our new laser.

[rvincent]

I know we can power the F-6 :D Sounds like I need to get one and test with it! I love planes that others don't have at my field! As for the F-104!!!!!!!! I NEED one now!! :D I'm posting from my BlackBerry right now as I *m not at home, but I will look at both these beauties when I get home! 15oz's..... Does it have an airfoil? I'm guessing we're gonna see 75+ mph out of this plane with our Park Jet motor.

[P6Mole]

Hi all,
Long time no post. The F-6 rocks. I built one of the first run of 4 kits for GAD and built it in around 3 hours. I cheated because i used the original wing from 2 years ago!
My maiden resulted in the plane prop hanging at about 6 ft. About 1:1 power to wiaght ratio with a micro6. Hmm CG to far back. We adjusted the CG and after a poor launch the F-6 rocketed into the floor about 10 ft in front of mike. Lol. Now that the CG was found using my plane, the F-6 flys like a dream. Mines all glued together again and I can`t wait to get mike to give her its maiden.

[P6Mole]

It lives!!!!!!! Mike I launched my F-6 and mike got it under control very quickly. Pulled away and did a few circuits. Cheeky roll and all was good. He passed the controls over to me and I did a few more circuits. It was a little blowie, so I neede full throttle to fly. As you can imagine the batteries didnt last long. As soon as the power started to drop-off, I brought her in for a carrier style landing. It glides well but the "wind" affected my landing lol. I flys well with a micro6 with 6x6 prop but it needs more power so you dont have to fly at max chat all the time!

[poacher]

A quik update, and a few pics,
We, Mike and i have been finalising the beta kits over the past few days and they will be ready to post out on tuesday ( monday is a holliday here ).

Mike would like to appologise for the lack of upades ect over the past week,
He's been at work and and without a working pc.

[poacher]

One more thing ...
Could the beta testers (you know who you are )please PM me or mike with there addresses so we can get the kits out asap.

Bry

[P6Mole]

That looks the dogs ********! I can see you boys have been working very hard!
I hope your having lots of fun to go with the hard work :)

[The Captain]

Does, doesn't it

Mines all done and ready for its maiden tomorrow :eek:

[rvincent]

Well!!?? How was the Maiden?

[The Captain]

Hi Guys

Maiden was a huge success :D :D :cool:

Powered by one of those sf3000's i followed Mike's advice on launch technique (for a change :eek: ) and it worked brilliantly.

Launch was at just over half throttle, with a faily firm flat throw. The Lightning climbed away easily - bang open the throttle and pull up into a near veretical climb in true Lighning style :D . Safely away from the hard stuff level out , hardly any trimming required to get her flying hands off :)

Still at full throttle and she's really quick - only slight problem occuring at this point I think I may need a more powerful elevator servo as flat out in a steep dive ready for a high speed pass over the strip she seemed to run out of elevator making the pass rather lower than i had intended :eek: - got cheers from the assembled spectators though :)

Low speed handling is excellent to - still plenty of response to control inputs and if you cut the motor completely she just glides on and on.

In the air the Lightning really looks the part - I remember watching them flying over the moors in northern england when i was a kid in the '60's. One of the guys i fly with now is a retired RAF Air Vice Marshal who has actually flown the real thing - even he was impressed.

Mike - you've got a real winner there mate - just got to pretty it up ready for the show season - oh and sort that elevator servo :cool:

Get your orders in now folks :D

[P6Mole]

Nice one mate!! I love it when a plan comes together!
(I watched a thing on telly about the A-team the other day).

The F-6 is a trully cool looking plane! Clarkson thought so too. That is why he had the lightning from the gates of RAF coltishall, moved to his front yard!

With RAF Coltishall closing at the end of the year, it is good to see some of the classic jets still flying there in model form (F-6 lightning and Sepecat Jaguar).

[poacher]

Beta testers please be aware your kits were posted 23/6/06 last friday.
They should be with you soon.

I have included a Cd with a beta manual and as many photos as i could find to help you with your builds.

as always myself and my colleages at green air designs will be more than happy to receive questions and alterations by PM or email
We need the feedback to help us improve the kits and manuals.

we hope you have fun with our new baby !
Bry

[Littlescreamers]

Hi,

we have received the kit and everything is nice:D I am going to let Bob build it and he will do you right.

Scott

[jzanutto]

Howdy, got mine on Friday, just got some UHU as well. Looks really nice in the box.

Jan Z

[jzanutto]

Are there any full aircraft pix of this paint scheme?

[jzanutto]

ok this is it....

[dusmmdb34]

received mine as well. Looks good in the box. I leave tomorrow on a business trip and will gone for two weeks. As soon as I return, I will jump right into it

Mike

[mjblack]

Hey guys, glad you all got your new toys, hope you have fun and look forward to hearing your exploits in the build and flying.

Any questions please PM or email so we can improve everything.

Fro those of you asking about the F-4 it got its maiden tonight,(sorry for the long delay) as you can see shes built very agriculturalyand quickly, but test flight went very very well, got the old C`o`G wrong on first flight .. :eek: ...too far back but secong fligth perfect......looks rigth in the air and fly right....just need to go fro some more testing see if we can improve it at all, but shes sweeeeet.



ahhh forgot to mention.....the snout was a throw-on just to sharped the front, a proper nose will now be fitted as she flies fine!....lol

[Andy McCowan]

Nice one Mike! :)

[DCobra]

I second that! It's always amazing to see what you GAD guys can do with black depron!

Congrats!

Paul

[mjblack]

Hey thanks guys, the kit is alot nicer than this build i just threw it together to see if it worked or not....all the stories of f-4`s and that, but she is straight as a die in the air....will bring you more info as a few more get made to test the kit...we wil be looking for beta testers when the kit is released in about 3-4 weeks.

regards,

Mike.

[Andy McCowan]

Mike,

What kind of size is the F4, motor,cells etc? Just curious in case I have anything lying around that might fly one. :)

[mjblack]

Hi Andy,

F-4 is 24" im using somthing like an align 400, but mega 4T, SF-2500 or pretty much and 400size brushless will push it about quite nicely, i have found a base system of a HET micro6-15T 6x6 prop adn 3s lipos will fly everything in this scale we make, trouble with the f-4 is the prop to rear end clearance for the HET motor.

Any thoughts?

regards,

Mike.

[The Captain]

C'mon then you beta testers it builds real quick and i'm just pleased i'm old enough to remember the real thing to compare how good it looks. :cool:

Smoke and thunder hog F4 eh - 2nd coolest plane after the F6 - never forget watching both over the yorks moors when i was a kid :)

Yer thats a young kid not a 40+ kid as i am now :rolleyes:

[mjblack]

Hey all,

Just a few more pics of the F-4 in the air finaly, needed someone here with a camera to take`em.... :rolleyes:

She also has a temp canopy, please let me know your thoughts.


regards,

Mike

[Andy McCowan]

Mike,

Looking at the piccies it would seem there is not much room to move the flight pack forward to make it balance if the motor was spaced a little rearwards to give more clearance for the prop. I guess you will just have to put up with the noise it is bound to make when the prop is that close. :)

You could always redesign it to fit the motor in the fuselage using an extension shaft to the tail but that gets a bit complicated! :eek: ;)

[mjblack]

Hey Andy, you have sorta hit the nail on the head there, the motor is zip tied on with the mount i have incorperated, you can however move the motor back with spacings, the trouble here is that the rear of this plane if quite complicated, a: in its shape and b: withe the elevator linkage and motor wires runnig through a small space.

This is my next mission to be able to put donw on paper how to make the linkage up adn motor so that there is on ambiguaty on how its made.

She is now getting filler ready for paint, should tidy up everything and make what looks like a rough build into a good looking plane..god willing.

regards,

Mike.

[jzanutto]

I've started my beta F6. Someone tell me WHY I am using UHU POR....... does anyone like this stuff?

[jzanutto]

Here are a couple of pix. As you open the box everything looks real nice- the laser cutting is crisp, stuff literally falls out. This is my first depron jet so I'm learning as I go. So far the fuselage is building like a balsa kit- except the UHU glue takes some getting used to. I'm right in the middle of a kitchen remodel too- so I'm laying tile, waiting for that to dry- then I glue plane parts and wait for them to dry. Somewhere in there I have a day job too...

[jzanutto]

A little more work this evening. Bottom of the fuselage is in place, also ventral fuel tank in place.

[poacher]

Looking good there, por glue is a contact glue spead it on thin on both side of the joint you want to make and wait 5 mins. when it's dry put the joint together and apply a little pressure it won't come apart again so get it right first time. the thinner you spead it the faster it drys.

Jan, thanks for the pm.s we'd like you and the other beta testers to post what you find in the groups, it's a great way of correcting and improving our kits, you'll also get a quicker answers to any questions as all four of us can pick up on you're posts.
2100 mAh should be fine but you have to balance that with the amp draw of the motor, i don't know the motor you're using so maybe someone who does can help with that.

Unfortuantly we have day jobs too.

The proto is covered in solafilm on a low heat.
Nice looking kitchen dude.!

Bry

[mjblack]

Hey Jan,
Looks great so far, The UHU thing..we to be honest i dont like it either particularly, so use epoxy, and spraymount for the layered parts, just a suggestion, might make th build easier or quicker.

You will be please to know that the F-4 is almost in kit for now so that wont be too long.....

oh.....bry....i used "PROFILM".....lol...............

Keep up the good work,

regards,

Mike.

[poacher]

DOH !

Ok so i is stupid,
but at least a can miss a tree, and I've never been shot down in a dogfight with a pigeon... :o
ratflmao

Bry

[jzanutto]

Do you think it will be too heavy if I paint it? I have an Align 3550KV motor that I had in my T Rex helicopter. I have a nice little 4 X 4 prop for it, and already have the 35A ESC and hyperion 2100 Mah battery pack. I have used that combo several times on the T rex.

[jzanutto]

I am making a log on MS word- I will just paste what I have down so far:

F6 build

1. as it comes out of the box- laser cutting is clean, parts literally fall out
2. instructions on CD seem very clear, organized, easy to follow.
3. UHU glue blows!
4. gonna have to turn off the Adobe spellcheck- US versions don’t like Euro words like TYRE and COLOUR
5. pictures need to be closer/clearer
6. is it really necessary to make the fuselage sides and bottom out of separate pieces? could you get longer foam and a slightly longer box, or is it a big cost savings to manufacture it this way?
7. so far everything fits ok. Fuselage is ¾ framed up.
8. what diagram do I use to measure the rib spacing? Should I just equally space them? There are no measurements provided.
9. Should the 3 fuselage formers be longer so they touch the bottom skin?
10. When assembling the fuselage, it’s initially hard to tell what is the front and what is the rear.

[poacher]

Euro words :rolleyes: ??? That's the Queens English man, the way it should be spoken, not the way the talk in the colonies. lol

I don't know why you're pc is opening it in Adobe, I thought I wrote the manual in word ! It should be a .doc file.

The fuse is made out of two parts because of you guys in the U.S. to make it any longer we'd have to put it in a longer box, if we did that the postage to the states would go up from £5.50 to £25.50 ! Would you want to pay that much in postage or make one glue joint ?

Rib spaceing ...good point. mayby Mike has some idea coz i just busked it !

The fuse formers help you in the build to keep things square. Once the fuse is finished they become less important, but again good point.

The photos are reduced in size by word, hence the cd having the full size ones encluded. Would a manual on a cd be acceptable or do people still expect a printed one ??

Painting should be ok test the paint on a scrap bit of depron first though.

Keep up the good work dude , and thanks for the comments, they are noted.

Bry

[jzanutto]

Depron wing ribs- no flat solid wing on this one! There is an upper and lower wing skin with an airfoil. Bry, does that help low speed handling?? You might need to have some available with printed manuals, some might prefer paper. (although I know you could just print it out from the disk)

jz

[P6Mole]

We have started etching part numbers on most parts to avoid any confusion. This will make building a doddle. Might have to mark front and rear on the fuselage as well. When you spend days designing and developing these type of aircraft, it becomes easy to remember what part goes where and which is front and rear. Thats why we need you guys to point out these things.

[jzanutto]

Awesome. I am also building a laser cut balsa Pilatus porter, 40 inch span. Their instruction book has a top view of each sheet and an index to show what each part is. It makes it really easy when pulling parts- and easy to find as well. If I'm looking for a certain part I know to go to sheet #3 and look there. It makes more work for you designers I know. This is my first GAD kit and I am happy with the quality.

[poacher]

Pics of 2 out of the three test bed planes flown last week.
The first of the kits will be cut this weekend and go on sale in a week or so.
We are developing a range of kits to sell for around £25.00 a kit. Hardware pack and glass included.
The kits are laser cut, easy build (2hrs) with a gluegun, and great fun to fly.
We had a ball testing 'em :D

Comments, requests, suggestions (clean ones please) welcome.
What kits would you like to see in this price range ?

Bry

[rvincent]

Nice!! :D

We could really make that one go! What is the span and AUW?

[poacher]

Saab

Span is 50cm
AUW 500g with a 2200mAh 3s1p 20c pack,

28" Vampire on the way - Maiden on Monday.

[jzanutto]

I've been sorta side tracked or this would be done by now. It's a quick build actually. I have the aileron servos in the wing and it's ready for sanding, then mount the motor and top of fuselage. Next will be the elevator mechanism.

I've found that 3M spray 77 adhesive is a lot better than uhu por. It does not attack the foam and its a lot easier to apply in spray form than the tube of POR. Plus I think you get a lot more adhesive in the spray can than you do in the tube of POR.

I still am using epoxy though, like to join the wing to the fuselage.

[jzanutto]

here's my solution for the motor mount. Its epoxied into the back before adding the twin exhaust rings. it's already sanded round to match up with the upper exhaust ring. I want to get mostly done tomorrow, because I have to go to Palm Springs for the whole next week.

[jzanutto]

this thing has lots of curves and bumps in all the right places. I like the ventral fuel cell, it looks like its going to be excellent for hand launching. I've got my wing sanded and the ailerons almost hooked up. I am going to paint it- what's a good way to fill the voids without making it heavy?

So I guess the motor and stuff stays in until you crash??? There's really no way to get at it once it's installed.

[jzanutto]

big problem here- unless I did something wrong. Once the elevator "crank" assembly is bent to shape there is no way to get it into the fuselage- so how did you do it?

[jzanutto]

ok sports fans, I got as far as I could get and now I've got to go to Palm Springs for the week, where it will be about 118 degrees. The motor, ESC, battery pack, radio are all in and ready to go. The CG is perfect with the hyperion 2100 mah pack up front. All I have to do is add the upper fuselage decking, the vertical fin and the canopy and it's ready for the maiden voyage. Wish I could have finished it. I think I will just fly without any paint or finishing to see how its going to go, seeing that this is my first depron jet. I dont have any problem with flying skills, I just want to wait to see it perform first.

a couple of other observations on the kit. No nosecone or hinges supplied.

[poacher]

Jan ,
you are look good there,

the plane will fly fine, just needs a solid launch and away she'll go.
check the cog before you fly, make sure it's as per the manual.
Hinges and nose cone, are already in the kits, soz you got a beta one.

Hope you enjoy Palm Spring,
Bry

[P6Mole]

She looks fantastic! unlike my vampire which ended up in about 10 bits after its failed 2nd flight.

[poacher]

Mole dude, I'm not letting you anywhere near my Shrike....lol

Bry

[P6Mole]

I cant wait to see it fly. It looks HOT! As for the vampire..... Battery problems resulting in smoke. Been Flying the eurofighter today. 2 Flights with no crashes. My flying is getting better!

[jzanutto]

bry, the manual says 225mm right? thats 8.85 inches. And that is measured from the flat part of the front of the wing right?

[poacher]

Jan that's correct.
good luck.

Bry

[poacher]

Jan,
As per the pm, the F 4 beta kits are being cut this week.
When we are happy withthem The first one will be heading your way.

The model has a proper built up wing section the same as the F 6, not a flat plate, and a fully flying tail. It's of a similar build style as the F 6 to get "all the curves in all the right places" as you put it..

Once again thanks for your help, all the points you have flagged up have been noted, and will be worked into the manual/kits.

Bry

[jzanutto]

sweet!

[jzanutto]

OK- it's almost ready for the first sortie. I need to devise a latch mechanism for the canopy, and I need to also find a way of securing the battery up in the nose. If I move it an inch forward or back it changes the CG quite a bit. It's just too hot here though- 112 today and all anybody wants to do is spend time in the pool.

[jzanutto]

finally got out and flew it today! Well I dont have enough power- I think the Align 430L is best suited for helicopters. My first toss was at 3/4 power, it torque rolled to the left and I was slow on the elevator so I bounced it off the grass. Next couple of tosses at full power, and I finally got a nice smooth climbout and got it trimmed.

It is a very smooth flying plane, and has no bad habits at all. My motor cant handle the 100+ degree heat so I only got a couple of short flights until the motor started cutting out due to the heat.

It flies like its on rails, I cant imagine how it would be if I had enough power to get up to a high speed. Low speed is very nice too, I was expecting it to drop like a brick when I pulled the power back but it's glide ratio is pretty good and I was able to do some nice smooth belly landings.

I havent weighed it yet but I am sure it's in the 25 oz range. So, I need some recommendations for 11 volt pusher systems that are great for this weight range.

[poacher]

Well done Jan.

The motors we have tried are the Sf 2500 and 3000, the HET micro 6 15 turn with a 6*6 prop and the 16/15/ mega range 2 to 4 turn. The 3 turn would probably be the better one to have. The Micro 6 is the best allrounder as it gives good speed, good thrust and low amp dump so long flights. but is not a quick as the mega.
Get the power right and you'll have a great plane there.

Are you still you for a F 4 beta, now you've mastered the GAD way of building ??

Bry

[jzanutto]

yup, bring on the the F-4. I like the way it looks as compared to the other one.

what power did you use on the F-4?

[jzanutto]

where do I get a micro 6?

I just went out for test flight #2. Before scrapping the motor I decided to go up to a 6.5 x 4 prop and see what would happen. WOW, twice the power and twice the speed- now we have a real jet. BUT it still gets hot, starts surging and shuts down. WHen I land the motor is really hot, I cant feel the ESC. So my question to all you electrical geniuses is: is it more likely that the motor is getting hot, or is the ESC maybe getting too hot and shutting current delivery off to the motor? I dont see that I am using any different combination of power than several others in their posts on various planes. I have a 25A ESC, 2100 mah 11.1v hyperion pack and a 3550 KV motor which originally had just a 4.5 x 4.5 prop. Prop size really doesnt affect this problem. Initially it just seems that the motor is a piece O crap. Any thoughts???
oh, by the way, it has enough power now to slide across the grass and take off- but it turns left before it gets enough speed to lift off.

once the motor cools for a couple of minutes it runs fine again. it is an Align 430L brushless (3550 kv)

I tried another motor. see my post about the littlescreamers parkjet motor.

Was this a PJ or a PP?

wow, now I have the combo- I put on my Eflite park 370 brushless outrunner and a 9x5 prop. Talk about a rocket! I had to change all my trims from yesterday's flight. I was able to fly 21 minutes again at about 3/4 - 7/8 throttle with bursts of full power. Absolutely no power problems- no cutting out, no surging, just flawless power and flight! I might go down to an 8x4 just to see what happens if I let the motor spool up a little bit more. Its a 1080 KV motor. After landing the motor was barely warm, and the battery was barely warm. (battery is a Hyperion 2100 mah 3 cell). Now I'm ready for the GAD beta F-4 kit.
