To Synthesize or not to Synthesize

[Happywing]

I think synthesized means you have a choice of all the channels, 61-90. With DSM (Spektrum) you have a channel that comes from a bank of thousands of channels. If someone happens to have the same channel as you, your system will automatically find an open channel...in milliseconds. As for the expensive servo. If you race, I think it's worth it. Digital servos center better and are a little faster. If you just bash, there are plenty of strong/fast anolog servos for a good price.
