The ZAP is a nine channel radio... the last channel is two state. Without the last channel my smoke wouldn't work so believe me the ninth channel is useful even if it is two state. For that matter I think the 10th channel on a JR 10x is only 512 PCM resolution... but I could be wrong. Gee... its too bad the Multiplex 4000 only supports five flight modes... Guess they had to ditch something to squeeze all those channels in... what was that called again? Evolution? OK, Sorry... me bad, but I couldn't resist.
I think both those web sites are a little off base. I have personally verifed that PCM appears to have better range at least during ground checks. We also have some pretty crappy weather here in Nebraska and I have never had any atsomopheric hits and I've even flown with thunder storms only a few miles away. Then again, what do I know... I'm just a monkey with a simple run of the mill 9ZAP

This thread makes me tired.
