i used a 9chp with a 29mhz module to fly my friend's school project aircraft. Today was the first time using the 9chp which belongs to the school as well. previously i was using my own tx/rx for the aircraft and it worked
did the usual ground checks for orientation and response, all was ok. antenna was extended fully.
so upon hand launch, it was going straight and true in a climb attitude. then, when i wanted to throttle back, there was NO RESPONSE! it was still at full throttle. it started drifting right and did not respond to my aileron or elevator input. gradually, it rolled right and nose dived at full throttle into the grass. thank goodness it missed the concrete by 30 cm and the damage was repairable. there was no jittery behaviour so a signal clash is unlikely.
has anyone seen something like this before? this occurred at jurongwest
when we got to the a/c, i tested the whole setup again. now all the servos were working. strange huh?
i'll be changing the tx module and rx for the next flight
