RE: PCM vs. FM
some top show pilots ive talked to dont use PCM - principally because of the lockout function. Theyd rather have a glitching plane and have some control over it than a model thats gone into failsafe.
i'm however sitting on the fence here when it comes to this debate - thats why i use the multiplex IPD receivers, which combine all the plus points of both at a cheaper price than pcm. the only problem is crystals cost more.
