A couple of weeks ago I posted  blog on fitting an the APM in an electric ducted fan.

Today, I flew it with APM stabilize enabled.  I tried to do a loop with stabilize on and it stopped at the top of the loop, DOH!

Otherwise tried manual mode and put the plane in unusual attitudes and then switched on stabilize and it was PERFECT, wings level straight away.  One of my retracts failed to retract and failed to lock resulting in a not so good landing.  I would have to say that the F22 is a very stable EDF and is able to be flown slow and the flaps and leading edge slats ready slowed it down for landing, but like all jets, pilots tend to fly it like it stolen.

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.

I almost lost my Skywalker today after making adding dual rates to my radio.  Originally I had 60% rates on both manual and stabilised flight modes, but I found on stabilised flight it was very sluggish, but perfect on manual.  So I set 100% throws on stabilised flight which as I found out is way too much.

A few minutes into the flight, on turning crosswind it went into a spin.  Probably induced by too much elevator and aileron.

Heino, Jeff E and myself have been working on updating Ardustation code to support Arductoper 2.

I think our code is ready for general use.

- Automatic antenna tracking, tested with ReadyMadeRC Antenna pan/tilt unit (even had my ContourHD cam attached to the directional antenna!)

- Manual antenna tracking (aka Antenna Test)

- Edit/View AC2 Params included PIDs

- Flight data display
