What a weird situation: I was out flying my Freewing T-33 today, take-off as usual, normal flight, then prepared for landing and after touchdown I let my beast roll out on a long concrete runway - maybe 400-500 meters/yards distance from where I stood with my Futaba transmitter. I intended to taxi back giving full right rudder/nose gear steering, but the beast did not react - instead it went full throttle without my giving any such command, by chance it took off again and only then I instantly regained command! I was lucky to have enough battery for a 180 degrees turn and safely landed again. Now what happened? There is only one explanation: for whatever reason, my Futaba R617FS receiver lost signal to my T10CG transmitter when the plane was rolling quite far down the runway and by failsafe default settings the throttle was activated. After lucky take-off, the receiver immediately regained transmitter signal and I had full control again.
=> Why would the receiver lose signal on ground? Was it my body physically covering/shading the signal when I kept the transmitter position towards the beginning of the runway with the plane being at the end (just turned my head towards the plane to assure smooth rolling out, normally very concentrated and indeed did not turn my full body towards the end of the runway)?... really bizarr no signal issues before and the R617FS is equipped with two antennas! Anyone has any similar experience / advice to share for "far distant ground handling"?...
Thus far my lessons learned: 1) throttle failsafe position to zero 2) turn body/transmitter inline with the plane on ground 3) envisage short landing/avoid never-ending rolling-out 4) irrespective of 35 years RC model aircraft experience, always be prepared for the unexpected!!
As you can see, it is a simple concrete runway of some 500 yards length, no obstacles (but me...):
