RE: PPM, PCM ?
That pic of your avatar HS sucks, Sonnich. Sorry for your loss. I would prefer to use a PCM receiver in a jet, althought you can use a PPM one without any problems. (I am actually using a PPM futaba in the roo, in a very busy R/C club without concern) ... as you said , the PPM receiver forewarns you of some problem making the servos glitch, but IMO this is not as good as the possibility of activating the landing gear, speed brakes and flaps in case of interference as in a PCM receiver...
A good thing of the brand of turbine I prefer, is that there is a log of the interference hits
on the receiver after each flight... a good way to check how good is your radio link or enviroment. Most times, at the end of a flight session I plug the data terminal on the plane just to see this info...
