My head is spinning!! If this all wasnt' confusing enough it apears that FM and PPM are the same?
I'm just going to get a Hitec Optic 6 and I think it is FM or PPM and that should work with my futaba etc recivers.
8 or more channels? What are you guys flying?!?!
Got some MORE confusion for you. PPM and PCM are both "types of modulation" used on FM transmitters. PPM is also used on AM transmitters that some people still use. PPM and PCM are the way the signal is "coded" on the basic FM carrier wave.
"OLD STYLE" Futabas encode PCM at 1024 bits/sec and the "NEW STYLE", like the 14MZ, encode at 2048 bits/sec.
As for what I fly? Right now nothing that needs more than 6 channels.
I believe that "1024" and "2048" is the resolution, not the refresh rate. 1024 = 2^10 = the number of possible combinations of a 10 digit long binary string of 1's and 0's. 2048= 2^11.
