@ Robbie, Gary and Bob

When I am building and contructing a new bird, I also share all I know with others here at Wattflyer or RCgroups.
But my friend want's to sell a few kits, because he has a small machine shop with CNC-machines for cutting the rips.
But also he knows, when the first kit is out, there will be some copies soon.

Robbie,

I agree with you that some people expect a plane to fly perfectly from the start, and of course those are not the type of people any of us would like to deal with. I also believe that it's prudent to prove that the prototype will fly first...adjustments can be made after that. Personally, I'd be more than happy to purchase your plans if and when you decide to release them.

When I have time to finish the plans and protype test them, they will be made available. Currently there is a horten VII and a piper saratoga on the board.

Default horten wings

hi from uk i have read with great interest the wing things. speaking to the uk lipo god chris golds about his horten experience it would seem drag rudders are essential to have a good chance of success. i have just got a baby training wing a sort hortenette for 2gws 40mm fans with brushless lipo combo 38" span elevons and mixer but it has a vestigal fin on its belly as a skid but more usefully as a fin! my bell imel is not going to use such a cheat! has anyone built one as per the plan ? and how was it? or do i need the drag rudders as per s/ldr golds original? god my head hurts! ciao

On another building site related to rc scale building, a horten 229 has been designed and the ailerons used were called frise ailerons. when the aileron is tilted upward, a small amount of the aileron leading edge protrudes under the wing, to correct the adverse yaw created by the downmoving aileron on the other wing

Default ho 229

hi thanks for the replies .the frise aileron i can understand but what about yaw stability? it seems to me that only some sort of drag rudder can provide this, especially at low speeds.either a scissors type a la chris golds ho or split flap type . has anyone built the bell- imel ho as per the plan? or maybe a small fin and gradually reduce its size?this is getting interesting!

The frise aileron works like a drag rudder under the wing, to reduce (and possibly eliminate adverse yaw.

I would say building a flying wing with some sort of rudder kinda defeats the purpose.

Cheers.

The drag rudders are really spoilers on the outboard section of the wings, the full size aircraft had them to allow it to Yaw. The frise ailerons are just intended to correct the adverse yaw when turning.

The bell imel designs have all been flight tested. After speaking with them, i'm sure that it would fly awesome when built as per plan. Looking at the specs of their UAV they definitely know what they are doing. the whole issue of drag rudders isnt really necessary, if they have been designed in, its because they were needed. If not, dont worry about them, you can always modify later if you need to.

Hello!

Made some starts at the bungee at Sunday afternoon!
Scale 1/10 = 1700mm wing span
To check the controlls and the calculated CG, I made some tests at the bungee. The controlls worked perfect, turns correct and is easy to controll. CG is a little nose heavy, could move it 10mm back. As a glider the weight is almost 1900g, because I need a heavy battery to bring the nose down. When I will set in the 2 Minifan with 2 Het 2w20 it just will gain 300g. I hope to test her with EDF next weekend, if the weather is still ok.

Hello!

I made 2 short powered flights at Saturday with my Ho229 V3. (then the rain starts!) 2 Minifan, 2HetW20 at 2 packs 3s1p 3200mA. Still have to adjust the thrust angle a little, program some more expo to the elevator function and also I have to test the thrust of both EDF, they are not equal. Flight was ok, airfoil is well calculated, no bad surprise at all!

Hi Heiner,

Congratulations on your maiden flight! We are some weeks (maybe months) from first flight of our EDF version. There are five guys with parts, it's a race to the finish to see who flies first! :-)

Best of luck with your project. Is someone going to make a kit of your version?

Gary

Hi Gary,

send me a kit of your's and I will fly first .... (joking)

Yes, a friend of mine will create an CNC-cut kit of my Ho229 V3, including a building bed for the right washout and agle. (will not work out without!)

Hoping finished in spring next year.

I want to tell you guys again how much I enjoy reading all this info. The information on this site is second to none. I still want to try my hand at a kit.

for those with a hankerin for some x planes from ww2, IL2 sturmovik '1946' edition has just been released and you can pilot and fight in very realistic renditions of not only the Ho229, but others like the huckebein, me262, me163, mig9, yak15 and much more...about 200 planes to choose from in fact!!

Default Horton Ho229 V3 Flying Wing 82" span

Hi Heiner

I am starting a build of an 82" Ho229 V3

Do you know if it is possible to fly the above with take off from the ground rather than hand launch.

Martin!

The 1/10 scale once I start with a bungee. My 1/5 Ho IXV3 has retracts!
