Im thinking of buying a new radio, preferably a Futaba 7C with the digital servo's but I also have a Hitec Optic 6 in mind... but I don't like the servo's that come with it, what would you think would be a better radio?
And another thing I can't figure out is what the difference is between PCM and FM?

PCM is Pulse Code Modulation while FM is Frequency Modulation.
PCM (pulse code modulation) is a digital scheme for transmitting analog data. The signals in PCM are binary; that is, there are only two possible states, represented by logic 1 (high) and logic 0 (low).
FM means that data is transmitted by varrying the frequency to either side of the middle carrier frequency.
PCM transmissions are much more precise in their data transfer and less prone to interference but it is not infalable.
Hey why not the Airtronics RD 8000?
