RE: PPM, PCM ?
Sonnich, Sorry about your plane. I hate all crashes but unexplained ones are the worse.
This is an interesting debate. I do not fly turbines, wish I could afford to. However, I do fly at
public shows from time to time and always use PCM with the failsafe set to close throttle and controls set for
snap roll/spin. This stops the forward flight path very very quickly so preventing the model going of into the distance/ crowd.
I understand the expense of doing this with a turbine model but at the end of the day, better safe than sorry.
From memory (and I could easily be wrong here), after entering failsafe the Rx should continue to look for the Tx signal (until the ground interrupts) so if you did not get control back PPM would not have returned control either.
I fly at a club with numbers limited by our landlord so we all have our own frequency, radio issues are not a problem.
Would this be an option, say 1 channel for 2 or 3 members, and so on? At least you could rule out other Tx interference.
Regards
Peter
