Programming the MGM with the radio can be a bit tricky. If your buddy is having problems, have him reset all to defaults and start over. The USBcom makes it so much easier (like castlelink). Yes they are in the Czech republic, and can take a while. I sent one in, not for repair, but for firmware update (old model). I have a couple and they work great. They are expensive though, but they run cool with no fan to break.

I agree... If you can use a castle MMM and 6s, then that would be best. But castle does not make a car controller for over 6s (yet), and an air esc just isn't the best way to go IMO.
