is anyone going to do a build thread?

[papasmurf]

and here is my favorite part "functioning intakes with flow through ducting". Can't wait to see someone stuff a fan in one of these successfully.

[Levi Jordan]

Keep us posted on how the builds go... feel free to ask any questions on the construction methods. Chris designed most all of it, and he just got registered here at RCGroups (he's a big turbine guy at RCU) so I'm sure he'll point you in the right direction for building.

[CRAZYPILOT]

Thank's.

cant wait to see it in the air.

Kenneth

[DCobra]

Foam is cut, and going to commence building. I'll probably have her in the air on Wednesday or Thursday if all goes well. I'll probably yank the electronics from one of my Jetset44 Park Hornets for the X-29 until I can get the wife to ok more electronics purchase.

Most likely I'll be using Himax 2015-4100, 5.33/1 gears, GWS 9070 prop, 8 cell KAN 1050, CC Phx. 25, GWS Naro servos, and Electron 6.

I'm planning to build the plane with XACTO sturdyboard and will glass the wing and possibly other parts for better durability/finish.

Paint scheme will probably be the NASA X-29 scheme so I can make use of the white foam and counter the fiberglass weight gain.

I'm looking forward to the build, and can't wait to see some flight reports and pics from others building this one.

@Levi- has this one been flown yet with power? Any video? I've seen the glide tests... awesome! :D :D :D :D Thanks for posting this one Levi!

[Iswald]

Good luck DCobra!!

[Stratotanker]

Glad you guys are enjoying the X-29, I should start building mine for a himax setup next week I hope,I am pretty new to electrics and am pretty excited about it, a lot less stressful than putting a turbine jet in the air! Let me know if there is anything that I can do to improve on the design. e-mail me anytime with questions/suggestions.

I can't see any improvements as being needed on the design...it looks to me like it's right on the money as far as scale looks go.

I do have a couple requests for the scratchbuilder plans, not sure if these should be addressed to Levi or not.

1. If possible make the lines for the template parts bolder. They were a bit hard to see when I was cutting, but I was able to get 'er done. :D

2. On the assembly drawings, I see a wing joiner where the CF rods meet. If possible, revise the part template with a copy of this for cutting out. I was able to get a template for that part by resizing the assembly drawing, hilighting that area, and printing only that area with that piece.

Other than that...thanks a bunch for designing and posting this plane! Can't wait to get her in the air!

P.S.- Welcome to EZone Stratotanker! :D

[EarlC]

Got mine all cut out and getting ready to start.

It appears that the Forward narrow section of the Fuselage bottom is abou 1/4" longer that the same part as displayed on the Assembly Drawing.

It also looks like the F1 bulkhead is wider on the detail than the Assy Dwg.

Can somebody confirm this or am I looking at something wrong.?

E

[Stratotanker]

Cobra, I will fix the lines and have Levi put redo it on his site.

Earl, I will check those out and fix if necessary as well.

Chris, thanks for the update...I'll probably end up building more than one of these (crash security :p ) and cutout of the next set of parts will be a bit easier with the changes. Thanks for being willing to take that suggestion, I felt a bit uneasy "complaining :eek: " about something that was freely given.

Have there been any powered flights yet of the original model?

[Stratotanker]

No Sweat cobra, Levi and I both are open to suggestions and constructive criticism. Your suggestions help us make a better designed, easier to build and better performing model for you. There seems to be a high demand for the park jets so they are being designed as fast as we can draw plus trying to stay on top of all the orders that flood in, Levi is working very hard to stay on top of things for you guys, I think he only sleeps 4 hours a day tops! We are currently working on the jets that are to be released on the website plus I will throw in unannounced jets to keep you guys on the edge of your seats! Powered flights will be soon, you guys will be the first to know.

Chris

[EarlC]

Chris:

Thanks for your reply. This is going to be a great looking plane.

I've got extra Depron and will be doing the Gripen right after your X29. Now all I've got to do is take a second on the house so I can put gear in all these Jets.

Earl

[Stratotanker]

The drawings are fixed, Earl, you were correct on the nose, I removed the tabs from the wrong side in the laser files, and the fuselage bottom was shortend by .020", you have an eagle eye! I will hand over the stuff to Levi to repost. I have also added 1/8 X 1/4 fins stiffners to keep the fin from snapping off for those inverted landings!

Chris

[Stratotanker]

UPDATE, If the weather clears, the Hacker B20-18L powered flights will be today.

[Iswald]

Good luck..

Hey Strato.... do you work with 3DFoamy?

if you do... you think you could slip one of these X-29s into my F-15 order "by accident"...lol

[absolute-zero]

I have printed the plan, and are ready for build, I only need more Depron, this will be in stock tomorrow. I will post some photos. I love this plane. I love these must have jets.

[Arbo]

Has one of these flown yet?

[Akura2]

That's what I'm waiting for too

[Stratotanker]

Hey guys, we actually got powered flight this evening!!!!!!! I just threw in a GWS drive and some servos into the test glider to check things out. The airplane was underpowered but flew well in our maintenance hangar at work. The CG was just in front of where we figured it to be with the test glider for safety. Aileron response was excellent, canards were way misjudged, we actually had 2" of travel measured at the leading edge so please pass the word to others building. Stall performance is awesome, no tip stalling at all! The Hacker powered plane will continue and should be an awsome performer. Use caution on the Canard throws as you move the CG aft as they will become more effective, possibly some expo. Levi is going to come on and discuss the power setup that was used and what should be used since I know nothing of the electronics stuff. Hopefully this will put your minds at ease. For those of you wondering, I do work with Levi and own my own Laser cutter and Foam cutter so I have been helping him out to fill your orders and am taking most of the designing load of the park jets so Levi can fill orders and work on other exciting kits coming out.


Chris

[Levi Jordan]

it was awesome!!! under powered with a sad gws drive.... but it flow out of my hand with chris at the controls.... gentle climb out, lots of aileron authority. with the cg set as shown on the plans, it flies like a classic canard would... absolutly no stall, but just a slight drop of the nose and a slow decent. There wasn't enout power to really get into high alpha... but the forward swept wing was super stable! we were tight on space, but the plane has awesome slow speed flight! and it looks really mean in the air.

[Akura2]

Video?

:D
I love you guys.... I mean that in the most plutonic way.....LOL

[Stratotanker]

We forgot the cord to plug the camera in, we will get it next time for sure! The plane definately looks different in the air, we will get the next one in the air as soon as humanly possible, I will try to post pictures of the build of the kit to keep you guys spooled up. Thanks for your patience.

Chris

[Levi Jordan]

Yours truely had the video in hand, all exiceted and stuff... then I realized the batt got left on, and the charger was at home 30 min away... I tried everything... even hooking up the camera batt to the lipo charger (darn fail safe stuff!) but could get the power. :(

[jforkner]

...canards were way misjudged, we actually had 2" of travel measured at the leading edge...

Strato,

When you say the canards were misjudged, do you mean the 2" of travel was too much or too little? Or was the 2" what you needed to control the plane?

Thanks.

Jack

[Levi Jordan]

2" was our final inflight requirements. The Previous thoughts were that it would only require .25"-.5" for pitch changes. It was realitivly nose heavy, so as the CG is moved back, Canard throw should be reduced.

[Spinner]

Chris and Levi,

That's great news! :) Congratulations on another fine design (seems like I'm writing these every week now!).

Were your flights for the c.g. location shown on the plans?

Thanks,
Joe

[Stratotanker]

The CG was sitting about 3/8" in front of the wing root leading edge and it is drawn on the plans at 1/4" ahead of the LE. The canards worked well, the plane really needed that 2" of throw once the plane was approaching stall and will be needed for the flare on landing. Can't wait to get some real power on this puppy and see what she can do!

Chris

[Levi Jordan]

Joe,

Do you recall the CG location on the real aircraft?

[Spinner]

Levi,

Here's a sketch from a publically available NASA report showing the c.g. located at about 7 percent AHEAD of the leading edge of the wing mean aero chord (sorry I don't have a fuselage station) on our large free-flight model. This is a representative c.g. for the airplane. BTW, the m.a.c. length and location is based on the wing planform without the wing-fuselage root extensions (Draw the leading edge line from the tip straight into the centerline). In any event, for this position the airplane was inherently unstable in pitch.

Thanks,
Joe

[Levi Jordan]

It is suprisingly close to the CG that the model we just fly was at... I think we were slightly forward of that location, but it was inherently STABLE, as the Canards were stalling and refusing to let the wing reach it's critcal AOA.

Just for clarification, is the canard throws 2" up & 2" down?
or is it total throw (1" in each direction) ?

Is the measurement taken at the canard's root LE?

Bob.

Hey Joe,
Can you explain how the aft strake flaps on the X-29 were used? Were they for pitch control or high lift?

Steve

[Levi Jordan]

Take at root LE. 1" in each direction. We ended up with 1.5" of UP pitch on the canard to pull a better flair at touchdown.

One nice thing about the Canard is that you can hold your flair till touchdown with no risk of riping off the stabs.

The next flights will be on a highpower setup, and we're going to play with adding some elevon mixing. Not sure it needs it though, it had good authority on canard only.

[CRAZYPILOT]

Found this on NASA-Dryden's homepage.

The flight control surfaces on the X-29 were the forward-
mounted canards, which shared the lifting load with the wings and provided primary pitch control; the wing flaperons (combination flaps and ailerons), used to change wing camber and function as ailerons for roll control when used asymmetrically; and the strake flaps on each side of the rudder that augmented the canards with pitch control. The control surfaces were linked electronically to a triple-redundant digital fly-by-wire flight control system (with analog back up) that provided an artificial stability.

Kenneth

[Spinner]

Levi,

Reason I asked the question on c.g. was that the c.g. on the 3-D model plans looked pretty aft, about where the airplane c.g. is, requiring all that computerized artifical stability!

Before saying anything else, just want to say that the 3-D model is an absolutely beautiful piece of work, and I'm buying one tonight to go with my F-18, F-15, Grippen, and T-38. Great job, Chris and Levi! I'm telling my friends to get one quick.

Walking on eggs here, cause I don't want to come across as a smart a--, just trying to be helpful to those who might be interested: After comparing the model and airplane lines, I think the 3-D model has a larger wing span and wing chord (i.e., more wing area) than the airplane lines to the same scale. Small increases in wing area make a big increase in stability for this layout. That could be why you have a stable model for the same c.g.position as the airplane.

Now--So what??? I don't care! This is a beautiful model of an eye-catching airplane, and you have come up with a design that let's us fly it without computers. GOOD for you!!

Keep up the good work, guys--you're great! :) :)

Joe

[Spinner]

Steve,

Kenneth's got it right! :) The strake flaps were on the airplane to provide trim capability to help the canard push the nose down for high alpha recovery. They were deflectable to 30 degrees trailing-edge down above about 20 degrees angle of attack. The design team was worried about the possibility of an unrecoverable "deep stall" due to the longitudinal instability, with insufficient canard effectiveness to get the nose down. Since they are so far on the back of the airplane, the starke flaps were very effective.

The other notable part of the airplane was the small nose strakes on the tip of the nose. They were used to stabilize the vortex flows coming off the mose at high alpha, because for the basic airplane (which used an F-5 nose) the vortices would shed asymmetrically, causing a yaw-off.

Hope this helps!
Joe

[Stratotanker]

Spinner, you are correct on the wing chord!, I increased the tip and root chords slightly to achieve greater wing area and lighter wing loading but I tried to keep it as scale in appearance as possible. Don't worry about offending us if you are trying to help. I am glad that you guys are enjoying it and thanks for all the compliments, it keeps us going when we are tired, I have to pry the mouse out of my hand sometimes, it has a lot of miles on it and still no end in sight! Each jet is going to become progressively better, I have a long list of secret projects that will show up unannounced and we will turn them out as fast as we can. Thanks for your support everyone.

Chris

[Spinner]

Chris,

You're great! Keep up the good work--we really appreciate it! And please, don't let the long awaited F-22 take much longer. ;)

Just fooling arround with AutoCAD I worked the CG out on the inserted JPEG. What do you think of this CG. AutoCAD finds the MAC for you and then you can work the percentage to what ever is workable according to the airframe.

Eric B.

[Levi Jordan]

The CG shown as shown on the plans is what we came up with mathmatically, and also through test flights.
http://www.3dfoamy.com/images/Parts/wpzdvvo9.gif

[AirX]

Ineresting, I suppose the MAC of the canard and the wing together is different mathematically for canards, I think i know what the difference is, it is the strakes. I will rerun it and see.

Eric B.

Letting AutoCAD find the centroid of the areas adding the strake area gets it really close but not entirely to the point where you have it, as it is I was just curious about the ability of AutoCAD to help find the correct CG for such a radical flying surface shapes.

[rcjetpilot]

Eric,

I think the margin of error is confined to (extended the canard dimensions) as we would normally do when adding the effect of a wide fusleage. If you recalulate the mac as percentage of actual wing area, you should end up closer to the CG that works.

I love this plane! so much so I built a IC version about 12 years ago. This one had a YS-45 with a tuned pipe and was a MISSLE!!!! and was quite stable. As with all of our toys, this plane ended as most, in a high speed crash:)

Digital pictures of some ancient pictures:)

[absolute-zero]

I will fly the X-29 i next weekend, if the danish winter weather will be less windy, then you can get your CG-spot. I will start a building thread.

[AirX]

RCJetpilot,

Cool plane, the YS is a missile maker... :)
Afriend had a Diamond Dust with one on it, lost it on the 3rd flight as he pulled up at the end of the feild and lost it against a cloudy background chopped throttle but could not reaquire it even though we wer pointing at it standing right next to him. Went in traveling at a frightening speed into a cement pad near a loading dock, not much left to pick up.

Cheers,

Eric B.

[rcjetpilot]

Hi AirX,

It was a cool plane, and it was butt ugly:) But oh man did this thing zoom.


All,
Just a few notes if anyone tries to experiment with coupled the control surfaces:

DONT mix in elevon control for the main wing and totally rely on the canard for pitch control. Why? It may result in a deep stall which is non-recoverable:) Good thing for me it happened while landing. However, mixing the flap-strakes would be VERY COOL!

Balance, very hard to get equipment layout to match the CG location, even with motor up front. I'd suggest you layout things well before you commit on placement.

You shouldn't need any washout due to the forward sweep, which creates the reverse issues of rearward sweep. The root section stalls well before the tips:) Like that helped me out when I crashed:eek:

And above all, this design can be made to fly very stable, and very fast:)

Bob.

[Arbo]

From my experience, AirX's CG is closer to what works than what is shown on the foam plan. I don't think edf vs. pusher would matter. Mine was just a bit aft of his. Where it's located on the foam plan always made it fly horribly tail heavy.

Paul

[clausxpf]

http://rcgroups.com/gallery/data/509/9500100_4104.MOV

this set up has wash out ... 2 degree... and a canard with a possitive attack of 2 degree.
we had to ad weight .... 35 gr.... the same as the airframe weight
to make this test glider ... 660 mm long fly as it should.
Most of the way it is very stable.. but when brought to extremes the radio control is a must.
but funny... the stall is like a harrier landing it just keeps level and land.
I have to tell the canard is not symetric.. a little more curve on the top.

I make maiden flight tomorrow......

[Levi Jordan]

Sounds great! Nice job and fast! The only caution I have for yout first flight is to let it fly from your hand... When doing out testing, I threw it hard, and once I slipped and pointed it down and we had to do nose surgery. :D

[DCobra]

That one looks great Zero!

Mine is still in progress, I finally got electronics for it today (from my crashed F-18 parkjet :eek: )
One thing I'm having problems with is the fit of my pieces, espescially the turtledeck piece. It seems like it tapers too quickly going back toward the vertical stab. It will probably make more sense when it goes together more.
I also had to redo the front top between the canopy and the nose cone. Apparently I sanded too much off my nose cone and the pieces weren't going to fit together flush. It's now been modded and looks good enough.
3 or 4 more days, and I might have something to show...I'm back to work tomorrow and hard to get the build time in after work.

I can't wait to see her in the air though... this is gonna be sweeeeeeeeeet!

[DCobra]

Absolute-Zero, how did the maiden go?

What setup are you using, and what is your AUW?

[Stratotanker]

I almost have the Hacker powered plane done, it has been hard to work on it this week, the real job has me tapped right now but I am working on it as much as I can. The Eurofighter is coming along nicely, I almost have all the parts drawn, this one has been a bit more tricky than the X-29 but we will get it licked.

Chris

[absolute-zero]

My maiden was good and bad.
After some great gliding tests (gliding very stable) I started my AC-DIYMOT-VR from Aircraft-world

http://www.aircraft-world.com/prodimages/AC-DIYMOT-VR.jpg

I have made some test on this motor in a GWS 370D gear (6.6:1) as a puller. I have 620g thrust (93W) but as I puller, the motor must run the other way, and I didn't have the testet thrust, mayby (100g) I discovered this on the field so I must test the plan as a glider with a little thrust, I flew 100-200 meter.

The problem must be the windings, missfire or things like that. I will try soon with a new motor, or direct drive with a smaller prop.

The CG is placed 1 cm ~ 0.4in in front of the wing, very near to the specified CG on the plan.


Stratotanker I hope you will releas the Eurofighter in time, I press F5 in the catalog on www.3dfoamy.com every time in have a little free time. I'm ready for a new build.

[Stratotanker]

We too flew the Hacker powered X-29 today!!! It was pretty windy here (10-15) but that didn't stop us. The CG as shown on the plans is where it should be... we did some experimenting with the range, from .5 in front, to .5 behind. Lets just say that you shouldn't fly it that far back... :D

First flight was with Hacker B20-18L, 2200 mah 3s1p pack, and APC 10x7 E prop (not slowfly) It has tons of power! Climb out was awesome, and the power off glide was right on. Elevator and Aileron control was very good, rolls were axial and in the rate of 360/sec on low rates (1/2" throw) Elevator authority was good, and took full throws(1 1/2" -2") for good flairs without power.

After a successfull pack change (landing), we moved the CG behind the recommended range (1/4" behind LE) and launched again.... it is pretty sensitive there... we flew for about 2 minutes, then lost it in a deep stall. It was a flat, elevator like decent... right into the ground. :) It would have been recoverable, but with the wind, it was heading back behind the flight line, so... EJECT< EJECT< EJECT... SO... keep your CG where we told ya too! Nose heavy (1/2") flight was controllable, but very sluggish, with very little pitch up with out power (no flair)

Now we're waiting for some nice calm weather to get some more flying and videos...

Chris,

Great news! Glad to hear it does what it's supposed to do relative to c.g. position! :) Give us some good vids!

Thanks for the flight report and CG confirmations Chris.

It's taking me forever to get mine built, other stuff keeps coming up. This work thing is overrated lol.

Typhoon will be cool! We gonna see an F-16 out of you guys "SkunkWorks" in the near future?
Back to the X-29, I have a choice right now of Himax 2015-4100 or GWS 350C to go in mine, but kind of holding back the Himax for JetSet44's F-15. Is performance decent with the GWS setup or barely acceptable? Keep in mind I'm still fueling my planes with nickel (till Christmas :) )and will probably come out around 17-19 oz fully fueled.

The F-16 will be after the Typhoon, most of the parts are drawn and the rest should be done soon. Please be patient, I put about 50-60 hours a week at my real job and I have a wife and kid. Levi will be the one to ask about the power setups, the GWS was not enough power for mine but it was set up with a rc car motor that I think was hurtng more than helping. He is always lurking in the forums so he will be here to help soon! Happy Flying

I definitely have the patience for the future designs, and I can relate to the job/family/hobby time juggle. I apologize if I came across as impatient or demanding. After all, you guys are doing us e-flyers a huge favor with these free plans, so for myself and everyone else who partakes of them I hope we never come across as having taken you guys efforts for granted.
With that said, I hope all of us that are flying these plans for free would be sure to recommend 3dfoamy.com to the folks that are going to approach us at the flying fields and ask where we got the plans, etc.
