I have receivers with glitch and blackout problems, my transmitter is an Futaba FF7 (PPM/PCM).
In my Multiplex TwinStar with 2xSP480, receiver ACT Micro6(PPM), I had short glitches 2-3 times in every flight without any BIG problems. Installing a FP-R139 GP(PCM) fixed the problem.
In my Multiplex Sky Cat with MEGA brush-less, receiver Jeti Rex-7(PPM), I had more glitches and total blackout when passing other Transmitters.
I'm thinking of buying a new Futaba receiver for my Sky Cat it has to be small of size and don't compromise range/quality.
Which receiver will solve my problems mentioned above(PPM or PCM ?, single/dual Conversion ?). 
Thanks for your time
