RE: Engine Kill...By choke servo or by ignition kill
The good news is that people have been flying both FM and PCM with gas planes, chokes, ignition cutoffs, etc for a lot of years. A lot of years before 2.4 DSS was available. Works just fine. Engines don't just quit for no reason with PCM and choke servos or ignition cut-offs. I've got 5 gas planes and never had an engine quit due to RFI kicking out either.
