F/A-22 Raptor Park Jet


The goal of this model was to capture the unmistakable look of the F/A-22 Raptor in an easy to build semi-scale model that could be flown in small fields. This model features a functional thrust vectoring (TV) system in the pitch axis, just like the real F/A-22. The TV system provides incredible maneuverability, enabling tight turns and loops, flips, tailslides, and greatly enhanced pitch control at low speeds/high alpha. The TV system is electronically mixed to the stabilators using transmitter mixing, and can be turned on and off in flight with a switch. The TV system is completely optional and can be omitted to simplify the model (this model is just as manueverable as any of my park jets without it).

This model is quick on the controls, but is stable, well-mannered and easy to fly. It was sized and designed specifically for the Littlescreamers Park Jet Special motor, though other motors could also work. Construction is similar to my other park jets, but is a little more complicated since it requires a lot of bevel cuts and extensive heat forming of the 3mm Depron upper fuselage.

f 22 Raptor


Hi,
Im currently building the raptor and just have a question about the flaperons and the stabs.
Whilst watching the video which is showing the thrust vectoring and the flaps moving, i noticed that they deflect in a opposite way.Is this meant to be the case as surely they then would be acting against each other and the desired effect would be reduced.
any advice on this would be great as i would like to sort this out before the bottom is fixed on
Cheers Chewi

chewi,
Yes, I use flaperon/elevator mixing on all my park jets. Dropping the flaps increases wing lift, which enables tighter and smoother turns. Yes, on a model like the F-22 where the wing trailing edge and tail are so close, the pitching moments of the two tend to counteract each other. However, I test flew my Raptor with the mixing turned off and on and thought it flew slightly better with it on, so I left it. This mixing makes an even bigger difference on other park jets, where there is more separation between the wing and tail.

raptor f22


That now makes sense to me. I need to accept the flaperons as just being a aileron control with extra lift and all the elevator control coming from the stabs.
thanks for your help

I don't have a circuit diagram. Take a look at the build manual, which has internal pictures showing where I put all the electronics.

This thread is quite old now. 6mm has a Raptor kit with two different motor combos as well. Which motor combo would you recommend for the Raptor?

Thanks!
