I've final finished setting up the worlds first (to my knowledge, and until proven otherwise) ArduPlane F22 Twin EDF with thrust vectoring, flaps, slats, and retractable undercarriage. It flies using delta wing mixing. With 6S 4000 mah.
Take off weight: 2.0 kg
Max thrust: 2.5 kg
Pre-flight complete, with Manual, Stabilize and FBW modes currently programmed. This should make this aircraft easier to fly. With a huge elevator on the back I might have to reduce the pitch PID substantially.
Comments
So where did you order this F-22 from? Was thinking of picking one up myself.
@John Hestness, it was ARF kit, took me only a couple of days. What added to the build time was the linkages were sloppy, so I replaced all the linkages.
@Dany, the GPS module is from my ArduCopter Hexa, as the Hexa has no canopy I thought it would be best to protect the GPS from scratches (when crash landing).
@Aaron, I've wired up the VT to separate aileron channels on my receiver and can turn VT mixing on or off. I don't plane on using it until I get the plane trimmed. However, others have flown it stock setup with VT.
@Darren, yaw induced spin in top gun was due to asymmetrical flight, only one engine was running. I doubt slightly off ESCs will cause a spin.
I just flew my Falcon EPO flying wing this weekend as part of my "training" to fly the Raptor. Unlike my Skywalker, the Falcon is FAST! It comes in hot for landing, even at zero throttle, makes good practice for EDF. I also just bought myself a Rebel 70 Sports EDF, it will be the next aircraft I fly before the F22 ArduRaptor. http://www.hobby-lobby.com/rebel_70_sport_arf_1034727_prd1.htm
I'm flying the EDF Habu in Phoenix RC sim quite well, grease all the landings, I just suck flying inverted.
A flying buddy of mine has a thrust vectoring F-22 (sans APM of course). They are a little dicey to trim our correctly because the thrust angle changes. Fly it with fixed thrust and get both the trims and fixed thrust angle dialed first. That should help a lot. I hope to see some video soon.
why the shrink wrap on the GPS module?
How do you manage to build so fast and still do a nice job? I have a single 70 mm EDF foam F-35 with vectored thrust, it looks pretty similar to your F-22. It also has full flying elevators, when flying it with VT turned off, the pitch responds pretty normally, it is the roll that is very sensitive, I assume that is because of the relatively short wingspan. So I think you are right that stabilize mode will make it nice to fly. Actually mine floats in for nice easy landings. One other thing I found is that the sound of my EDF at full speed really scares mothers with small children. Doh! only did that once.
I had not considered putting my APM in the EDF because of space limitations and the brief flight time but you proved it can be done and done right.
@Paul M. That must be the new bigger processor APM in that thing.
P.S. -- It was an autonomous jet.
Anyone remember Stealth? We might be there...
Very nice, is it from HK, NitroPlanes or ??
Take your time, create a check list, be sure it handles well in manual mode, then goto 50 meters and try Stabilize mode at normal cruise speed, Get a jet pilot to help you if possible, he could use a trainer cable to take control over when needed, Jets can crash very fast... I have rebuilt my Stryker II several times... (my traner jet...well prop-jet)
Good luck with maiden flights!, an onboard keychain camera video would be great.
Do you think I should take off clean or with flaps?
I've just finished assembling a Falcon flying wing, hoping to get used to the higher speed compared to flying my mini and full sized skywalker.
