Hurricane 550 is here, cheap, light and flies just awsome!

[swatson144]

3.5mm here.

Steve

[jmralves]

3,5mm also, cold after 8 min flight.

[caotri]

3.5mm too for motor and 4mm for battery connector.

[Phoinix]

3,5mm for motor, 4mm for battery

[Flinto]

Hi all.

I have a new 550 kit sitting under the xmas tree.
Kit includes motor only, so it needs pretty much evrything minus a RX

Looking to put adequate electrics in it at this stage as I am no 3D pilot by any stretch.

Most importantly, I want know if the servo's are correct for the hurry and also I remain unsure of what to choose as a BEC.

Would appreciate any positive input...

My choice so far..

Cyclic Servo's HS635HB x 3 http://www.servocity.com/html/hs-635hb_high_torque.html

[jmralves]

Flinto,

Upgrade the lipos at least to 2500mAh (ideal 3300mAh).

The selected lipos do the job but expect a current consumption of about 60 to 70A with the stock motor (maximum values, depending how you input the cyclic pitch)

[Flinto]

Upgrade the lipos at least to 2500mAh (ideal 3300mAh).



Do you have a have a particular battery in mind?

[Phoinix]

Go for Fligth power 5S 5350mAh if you are a learner. Not a 3D battery, but it can hang in the air for 13 minutes per charge (80% capacity). No other pack will give you that.

Take great care for any lipo that you run. Go for 80% discharge capacity and it will give you more than full cycle life.

[DEWorley]

i'm using the 11.1/4000 lipoly from TrueRC, $55 each.

[Flinto]

Thanks mate, thats food for thought.

So how about my servo choice....adequate?

Flinto

[L0stS0ul]

I personally went with these servos:
http://www.servocity.com/html/s3152.html

Same price as the ones you chose but are digital. Once I got the CNC elevator arm I was able to use the stock control arms without modification which was nice. Someone who has those servos will have to chime in on the horns that come with those.

The futaba servos are a bit slower but a bit higher torque than what you chose and they are digital. Not sure if you care about that or not. Just another option in that price range.

[GyroRon]

Wow... alot of posts in this thread! Way too many to read em all!!!

I am flying a T-rex 450, that I converted to a T-rex SE. I like flying it, and I am just starting to learn some 3D moves with it, but a long ways off from doing anything spectacular with a helicopter anytime soon.

My T-rex flys great, but it is a bit touchier than bigger helicopters I have flown - I have flown a friends T-rex 600 and his Raptor 50 and I had a Raptor 30 for a little while.

I am thinking of maybe selling my T-rex and going for this Hurricane.

A few questions if you guys don't mind....

1. What kind of Servos would I need? Right now in My Rex I have HS56's and a HS-81 on the tail with a Gy401 gyro.

2. How durable is the helicopter in the stock plastic set up? I ask because when my T-rex was mostly plastic, even a minor crash would just about ruin the heli... now when it crashes the damage is not too bad since the metal upgrade parts don't break like the plastic parts did.

3. Will the Hurricane fly good out of the box? Again keep in mind I am not a agressive 3D flyer, but want a SMOOTH and STABLE helicopter.... This was again something I had to work on my T-rex to get, it never did fly nice till I upgraded to a Carbon CCPM frame and upgraded to metal head and tail.

4. Will this really fly good with 2 three cell 2100 packs? Will the packs need to be modified to use on this heli?

5. Is the stock motor and ESC good stuff or will I have to upgrade to a better ESC right away?

If this thing is nice I might sell my Trex and upsize my heli flying order!

Thanks Ron

[misskimo]

yeh! its been over due for part2 , well along time ago he should have split it up

[Aussieflyer]

Flinto.
Wattsup page is not working, however the BEC i think you are talking about that they sell will not suit the hurricane. that bec can only handle up to 5 cells, you will be using more than that.
Good luck with it, its an awesome heli

Thanks for the heads up Aussie, I hadn't spotted that

[Capt. Crunch]

Gyro Ron,

The only things I can comment on are the servos and motor, you'll need much bigger than the minis from a Trex 450, I use F3151 digitals, and a 59253 on the tail, full size and the 3152 is a better deal now.
The stock motor will burn out before too long when doing hard 3D, but OK otherwise. The ESC seems good enough. Only a $40 savings to order w/o them, so just use till they burn up, then upgrade.

A friend of mine prefers his Hurri 550 over his Trex 600, both are stock, and he doesn't do agressive 3D. He feels the Hurri is the smoothest, most stable, and best he's flown!

Don't have any crash history, yet, can anyone else comment on that? All I know is the parts are very low cost compared to others.

Go for it, you'll love it.

[rjarois]

got mine ready to go.....i am going to use a koolflight 6volt ubec, instead of a flightpack. i hope it will be ok, it worked fine on my .90 funtana doing 3-D flying. anyone see a reason not to set-up this way?. also whats the biggest packs you fellas are getting the canopy over?, will 3300mah. fit?. thanks, peace, randy.

[swatson144]

The Koolflight is what I run on my 400mm 6S and it works great. I just went with the 2S lipo and regulator on the hurricane because there was room and it came with it.

Is that a new canopy? Mine has been shedding gromets and has been repaired twice now.

Does anybody know of a good canopy solution? The FG work OK now? I finally get my H550 the way I like it and now I'm scared of the canopy. I like the light weight of the styrene and wouldn't mind considering them disposable if the dang things were available painted and cheap.

Steve

[ukgroucho]

Nice.. what motor is that?

I think a separate SBEC is definitely the way to go.. it reduces weight and clutter (and minimises points of failure). The Kool Ubecs have a pretty good reputation from what I see so I'm sure you'll be fine.

I'm using 5S packs so not really a good reference but a 2300 5S fits into the 'body' on the CF frame and also on the battery 'slope' in front of the motor. Canopy is snug but fits well.

[rjarois]

steve, the canopy is the stock one.....just took red tamiya spray can to the bottom and slapped on some stickers......randy.

[rjarois]

ukgroucho, its a hacker A40-10S 10-pole......i got it from the local hobby store. its got a sticker on it from hacker..... B/L OUTRUNNER A40-10S GAUI 550. the paperwork says its a 930Kv motor. randy.

[spudandretti]

You still can run the ubecs and Cc bec off a seperate lipo, correct? like a 3s 1320 TP pack? Can't see no reason why not, but I might be missing something. Edit: Curious, because I would like to try some A123's someday.Bud

[rjarois]

no seperate battery.....tied in to the lipo for the ubec power. cant hardly see the 22volt lipo's going down past 6volts... as i got the cut-off set for 18volts. randy.

Yes you can use a uBEC as a regulator or as a BEC. Really not much point though you connect the uBEC or CC BEC to the main power plug and when you go 7S A123 they'll never know the difference. I'll probably change to uBEC but I have several 2S packs around that I no longer use on anything else.

I'm really liking my 7S A123 pack, changing back and forth to 6S lipo is just changing packs. I don't change anything else. :D Heck you can even charge a 7S A123 as a 6S lipo.

the canopy is the stock one.....just took red tamiya spray can to the bottom and slapped on some stickers......randy.

Looks good I really wouldn't mind a white canopy with the painted on windshield. I find it a lot of work to get a windshield painted even and nice looking.

My concern is the setting on the standard Gaui speedy for using A123's. I was thinking about replacing the speedy with something else, haven't figured that out yet ( I am up for possible suggestions :) ), but I know I will go to a higher amp one, for future motor change.

That's the beauty... No setting changes needed 3.6V*7 = 25.2V 4.2*6=25.2v. Just plug in and go fly. I do about 6mins in flight and then just practise slow piros and NI until it hits LVC.

I'm using the stock motor and ESC until I have some reason to change it, since it meets or exceeds my needs. I do have the 3rd brg and long shaft installed for later.

If I would of used a little brain power,huh? Thanks for the info. I probably too will stay with that standard stuff for now, doesn't make since to change something if it works, just more money saved to spend on something else. I do have the long shaft too and I have the short boom kit I want to try. I just don't know if my triton will charge the A123's I will try it. I was going to configure a 3s and a 4s pack or just go to a 7s for the A123's. I would have to have it as a 7s pack to charge anyways, or just keep them hooked up (3s+4s) using the connector I use for my two 3s lipo's i use on the heli. I don't know if its wise to not have balance adapters on the A123's, what I read so for its kind of 50/50, some do and some don't.

[swatson144]

UKpaul showed me the light on the separate 4S and 3S packs about 5 pages back. 3S low and 4S high on the frame.

I don't know about the tritons but I also have 2 of them so I should look at them for A123. They have pretty decent NiXX capability and the lipodapter (http://www.slkelectronics.com/lipodapter/index.htm) looks like an option.

I put balance connectors on my A123 it's simple and I used floppy (http://www.rchelicoptertown.com/forum/showthread.php?t=1700) connectors from old PC power supplies. The 4S pack needed part from 2 glued together.

Steve

[spudandretti]

Nice article. What size heatshrink did you use, if you don't mind me asking. Now since you set me straight on some of the A123 questions I had, I can't wait to try them out. I have a dewalt pack setting here, I almost was going to sell it, instead of using it. Still have to work on a charger, I don't know if the triton will work with the dapter or not. Plus I have a TP balancer, will have to read up more on what I would need. Still confusing for me, at the ripe old age of fifty my brain seems to be the first to get going out of town :D .Bud

[swatson144]

http://www.fmadirect.com/detail.htm?item=2131&section=38 was what worked. I also ordered some 96mm black which works but the other works with tri or flat packs so is handier. 1$ a foot ain't bad they'll change the shipping cost down to like 3$ or so and 1st class it in a padded mailer.

I'm 47.

I went ahead and ordered the heatshrink. I also went ahead and ordered the cellpro4s charger for the a123's and some balance taps. I know they are coming out with the 10s charger soon, but for what I need, this will be fine, probably cheaper then the new 10s too.http://www.fmadirect.com/products.htm?cat=45&nid=4

Is that a new canopy? Mine has been shedding gromets and has been repaired twice now.

Steve[/QUOTE]

You are not alone! I've only had my canopy on and off about a dozen times and its falling apart at the seams and the grommet holes are both breaking out. A slightly different material would be a partial solution. Wonder if a Clorox bottle will fit? Just kidding.......

I ended up having to put some of my blenderm tape on the seams and shoegoo around the grommet holes. It would be nice if they would make one similar to the plastic thats on my T rex canopy. At least I can bash that one around abit.bud

[mr fabulous]

hey there, ive crashed and i have bent the arm thats on the main blade grip that the mixing lever screws onto(cnc maingrips)ive done a search and it looks like that bit is not available seperately, so its gonna cost me 61 bucks for a new set of maingrips... does anyone know if this maingrip arm is available or do i have to spend $61 to replace a $5 part.... are there any alternate grips i can use(not the plastic ones)

[misskimo]

hey fab , the other day I was doing the finial touches to my trex 700 and noticed I had bent arms like you had on the avant programable head , I fixed mine in a vise , bent them back, I will order a new set . but I sure was wanting to test this bird if I got the chance while at home . a storm is brewing , so its warming up . YEH!

Tony

[mr fabulous]

yes misskimo, looks like i will go that path also....better hurry up n go flyin,time for beer later.....

[rcxm]

you can check main blade grips arm from cnchelicopter (http://www.cnchelicopter.com/servlet/the-CNC-Hurricane-550/Categories) , it may help .price is decent

[Modelholic]

Happy belated Birthday to this thread!

[Tom Viper]

Wow, time pases by quickly!
So, what has happend since the first post?

Well, I am still flying my first Hurricane 550. It has been upgraded with a motorplate and the new gaui "ok" gears. The head, tail and everything else is the same exept... the Agusta 109A body. It´s kind of retired to "soft and gentle" flying nowdays. This heli is the one I have most flights on amongst all my helis. Its now way over 1000 flights. And it´s still hungry for more. So, I must say, this has been a very nice helicopter, and very very cheap one as well.

My new 3D toy, the Hurricane 550 Carbon has about 400+ flights, and still going strong offcourse. Its equiped with a full CNC head, Z30 1100, gaui´s new thrusted tail. Its being "converted" to 8S soon for extreme power. So with the facts at hand, and a year of flying these helicopters I must say that
I have truly enjoyed them and still do. I was accused of hyping this heli about 1000 posts back when the thread was new.. well guys, I still do :D

Tom
Sweeeet! was that a body kit ? I just got my 1st flight on my CF Hurricane 550. All I can say is wow. I started flying a Black Hawk 450 and this is a big differance. Much more stable, even in ground affect. The only thing I dont care for is the plastric canopy. Anyone know a good place to get aftermarkit canopys for this Heli, maybe something with a cool paintjob?

There isn't much to choose from at the moment in H550 canopies. I just ordered a Fusino from Heli Direct its about $15.00 cheaper than the Gaui fiberglass canopy. They look to be a clone canopy with a small selection of colors. I won't know for a couple more days until the order arrives as to quality and fit. There must be something else out but I haven't found it yet.

[Modelholic]

Hype away Tom - the Hurri is definitely my best heli. In fact I am thinking of selling my 2 450 size helis to help purchase more batteries or maybe a body kit!!!

[misskimo]

huh? with all that bling and its still cheap , dude , you got to be kidding me

[MikeHRC]

I took my Hurricane out for a gentle tootle around today, I had forgotten how nicely it flies - very forgiving. It is about 0.5 degrees celsius here today (32 Farenheit). As well as my flight times being shorter I had to use more throttle to hover - is this normal ? Will I do my lipos any harm using them when it is this cold ?.

Cheers,
mike.

[FlybyPDX]

How is the durability of the 550 compared to the T-rex 600?

[swatson144]

Either seem to be very durable unti they meet with the ground then the ground proves the more durable.

Steve

[FlybyPDX]

The 550 looks like the frame would be weak in the front of the frame where the battery straps on.

[MikeHRC]

I am contemplating replacing my current 1,000mAH 2S1P battery plus Gaui BEC with a HV BEC - probably a Dimension SportBEC. If I were to do this would I simply put it across one of the batteries or after they are joined up to make 22 volts (the SportBEC is rated up to 33V) ?.

What are you guys using ?

Cheers,
Mike.

[Pinecone]

Biggest problem I have seen is that the boom supports are almost a joke, or fashion statement, rather than actually doing anything.

I have converted to shortened Trex 600 supports (CF tubing). I posted how to do it a week or two ago.

Just changed over to using one of these (http://www.airstrike.com.au/Hyperion%20TICOOL%20Data.htm), got it from Robotbirds, £20. 60 6min flights over the last 3 days & seems fine so far. Runs from the main power leads going into the ESC, so it's running from both packs. Saves ~80g compared to the 4cell 2100 NIMH I was using before.

Yeah, it was nice to be flying again :) Got to get them flights in while you can with all the wind/rain we've had lately. Been grounded for ~10 days prior to the last few days flying :( A123's, a Mastech 5020 & a small generator help out with back to back flights. You can soon clock up airtime using this setup, no waiting around in between flights for packs to finish charging.
With the NiMh 2100's I could get ~10 flights, then had to change models. I'm really enjoying the Hurricane at the moment, so the HV BEC rocks as I can fly till my thumbs hurt :D , weather permitting...

Hi!
I Use the Logictech 2100T gyro and at flight my tail turns slowly right at HH.
How Can I correct it? Does anyone use that gyro and does it make deferent whitch direction it will be sticks in gyro place (side,front,buck)?

[L0stS0ul]

I use the logictech. It's extremely important to get it setup properly in rate mode. If the tail does not hold rock solid at the head speed you will be flying at in rate mode then you will have drift in heading hold mode. When you do the rate mode setup make sure you set the gyro to around 50-60% in rate mode and when you do the hover test the throttle will be at your normal flight speed. You will also want to do the setup on a calm day when the wind won't be causing the tail to move. I do the tail setup in my garage.

[itf68]

Thanks a lot L0stS0ul for your answer!
In rate mode holds rock solid but when i try in heading hold start moving! The only think is to set gyro 50-60% in rate mode, and in heading hold too?
About the gyro direction?
Can you please post foto?

[swatson144]

I'd say double check the trims and subtrims then.

Steve

[L0stS0ul]

Here's to pics of where I have my gyro placed and it's orientation.

swatson144 is right, Also make sure your rudder trims and subtrims are at neutral. That can also have an effect.

[itf68]

Thanks both of you, i'll try again to fix the problem...!

[mr fabulous]

jus dropped in to say im still gettin my jollys flyin this thing... everything is still stock cept for cnc flybar cage n cnc pitch ,roll,elev. arms......with this and my mini titan im in a happy place :D

[Tom Viper]

Just want to chime in and say that something new and cool is around the corner. :D

[swatson144]

Great things are gonna happen in Jan?
Sheeesh so whatever you do don't buy an H550 until after Jan! Don't buy any parts as they may be lowering the price on the bling. Just wait, dang it, until the secret unfurls!!

I don't get it. Why pull the secretive I know something you don't crap. What? did friggen horizon buy Gaui?

Doesn't anyone else find it aggrevating to have a major vendor and others in the know hint at "something great" but not let you know what it involves? ie if it's new LG I don't care, if it's new frames it won't affect repairing a head...

Screw it then I'm getting another 400mm and parking this thing for a while. At least until they get done Osbourning themselves!

Steve

[ReadyHeli]

Just want to chime in and say that something new and cool is around the corner.
So for all Hurricane fliers, stay tuned for Jan -08 and check out the Gaui site...

This is exactly what GAUI does NOT want leaked...nothing is changing with the hurricane 550.

There is something exciting coming between a Hurricane 200 and Hurricane 550.

Please do not stop flying the Hurricane 550 or Hurricane 200. Both machines are here to stay, in their current form.

[swatson144]

Ahhh that brought a true belly laugh.

It seems that I can continue picking at the H550 and enjoying it. Which is pretty much what I was doing while waiting for some of the dust to settle in my favorite size range (400mm) before pulling the trigger on another one.

Wouldn't it be ironic if a hint of "something great" on a H550 thread brought me to go ahead and buy another 400mm that wasn't exactly what I wanted and then found out the something great from Gaui was indeed a 400mm? I've even sold a 400 to have something to replace. :D

Oh my god, i just got a fat one.
When and where can i get this stuff.....and how much !!!?!?!?!

[Phoinix]

Now that GAUI has the smell of money in sight, i wonder about these prices. I bet t-rex 600 prices will still be lower. GAUI CNC parts are platinum rated when it comes to prices.

A pitty, such a good start and such a shallow approach.

[HeliDirect]

these parts are aftermarket parts. They compliment well to what Gaui starts from the first place

I use the logictech. It's extremely important to get it setup properly in rate mode. If the tail does not hold rock solid at the head speed you will be flying at in rate mode then you will have drift in heading hold mode. When you do the rate mode setup make sure you set the gyro to around 50-60% in rate mode and when you do the hover test the throttle will be at your normal flight speed. You will also want to do the setup on a calm day when the wind won't be causing the tail to move. I do the tail setup in my garage.

I try today the settings and was the same :confused: , no different on heli! Can you please give me your settings to try on mine? My TX is DX7!

[L0stS0ul]

The only setting for the gyro for me in my radio is the gain which is currently set at around 75% I believe. I'd recommend going through these 2 threads:

They tell you all you need to know to get the tail holding well.

I've been out of the heli scene for a little while, but am thinking of coming back. Does this heli flies well out of the box?

[Aussieflyer]

Dude, it flies awesome out of the box.
It will be great for learning (post sim and co-ax)
It will also do just about any 3d with after market power system (motor & speedy)
There are three things that i would change for out of box, if you are getting the base model. cnc flybar cage....25 bux approx, raptor links....5 bux (watch finless bob vids to see why) and finally cnc elevator servo arm...15 bux approx.

[BoneDoc]

I'm a bit beyond coax :)... should still be able to fly backwards upright, and hold inverted hover for some time.

I have to put together my TRex 600 and 450 again. I do have a couple of 5S packs that would go well with the Hurricane though.

One thing with bobs video. About the head setup, I don´t belive he is all correct here. The head is constructed the right way, and he suggest that you should level the top mixing arm when at 0 degree pitch. This is not all true.The important thing here, is that the linkarm from the swash to the top mixing arm is at 90 degree. See image...

[Pinecone]

Problem is one of the two links will not be at 90.

yes, full size servos. Also adaptors are available for mini size. The rotorworkz frame will not have the front pulley second stage.

This makes complete sense to me now and was how I set my heli up. I had tried to get the rocker arm to be level as well with my setup but it's just not possible and mines setup exactly like that. I thought I was wrong in my setup after watching finless's videos but fly mine like it is anyway and it flies great.

[Pinecone]

It seems to fly well either way.

We need a really good flyer to try it both ways.

To get the mixer level, you need to make an adjustable short link. 16mm piece of 1-56 all thread and 2 Gaui links will do it.

[jmralves]

Folks,

I am trying to do some tic-tocs with my Hurri (they are uggly to see and the heli loose some height also. I am using 0,125s analog servos in the cyclic).

Do you use some sort of mixture or expo in the pitch curve around 0º to increase the speed of the manouvre?

My Hurri also rotates slowly (Gy401/Fut9650 allow 1 to 1,5 turns per second), How do your's rotate?

TIA

hey ITF68 if you go above 50% in rate mode, it goes into hh.. i set it in rate mode on the gyro on led no.3 , then on dx7 in whichever channel your using for gyro i set that at 40%, then on rudder in dual rate pos 1, i set that at 50%

for hh i set the gyro on led 6or7 ,then on dx7 i set the gyro channel at between 65 and 75% and on rudder dual rate switch pos 0, i set at 70%

I agree with this setup 100%. As much as a value Bob's opinion on head setup, I think this setup gives the least binding at the end of the ranges.

I was hoping though the link lengths stated on the drawing would be correct but they are way off.

Did I miss something here or is this just a generic head setup?

Does anyone have accurate link lenghs for this drawing? I am just re setting my links at the moment with this geometry and wouldnt mind a check lengh to compare with. I will post the lengths I come up with later on today.

[DEWorley]

kepler,
i made my pushrod lengths the same distance as the distance between the bellcrank pivot & the servo wheel pivot.

[Kepler]

Just finished resetting the push rod length for the correct geometry at 0 degrees (swash plate rods and mixing arms at 90 degrees). Rod length ends up being exactly what Gaui recommend in their instructions. How weird is that! Imaging the Gaui engineers actually being correct. Seriously though setting the swash plate rods to 81mm between ball centres or 53mm of rod expossed with the stock ball links being used gives the correct geometry and the least binding through the entire travel (+11 to -11).

I am using a metal head and metal mixers with the Bell side in the outer hole and the Hiller side in the inside hole.

The picture is from another heli, but the head is the same. So the link lenghts are not valid for the Hurricane.

Now that GAUI has the smell of money in sight, i wonder about these prices. I bet t-rex 600 prices will still be lower. GAUI CNC parts are platinum rated when it comes to prices.

A pitty, such a good start and such a shallow approach.

That stuff looks fantastic. The tail assy is definitely on my shopping list.

[Tom Viper]

How is the quality? In the past, these parts have been made with a very soft aluminium that bends easly. Would be nice to hear from someone that has tried these parts.

[Happy|Harry]

tom i have the whole tail setup en route from helidirect, i'll post my thoughts once it arrives :)

Ain't that the truth! Guy posts a link to pictures with little or no description maybe describing them would help. Are they made by gaui? are they the same dimensions and ratios as the gaui parts? or are they parts for something else that flies like a dog but fit a H550? Heck I couldn't even be sure he wasn't just selling pictures of them.

Steve

[Tom Viper]

No, these parts are NOT made by gaui. And as I look at the seesaw, it looks like its using bushings instead of ball bearings? This is not one of the parts where you should jump BB`s. Tail looks nice though, if its made right. If its soft junk as the trex parts, well... not worth it even at half the price.
