I check for interference with FM and then go with PCM on High dollar models. Both work but I think PCM maybe a little more precise and mask some FM(PPM) interference.

Nearly everyone that flies pattern uses PCM. I actually asked some top FAI pilots if they could tell a difference in then Futaba recievers(319/2048) and two of them said definately. They both claimed they had to add expo with the more sensitive RX.

For 60-90 I'd probably go FM/PPM.
BTW both are FM, they are just PPM and PCM.

I wouldnt get to carried away with either, I think spectrum 2.4 ghz will be the future.I just hope I just hope I only have to buy RX's and Module for my 9C.


rcpilet I see you like the Tower 75, Great engine that works as well as any OS I have ever owned.
