I have a three channel (TQ-3) radio that I'm curious about. What is the red switch for (you know, the one you like to fiddle with when driving)? Also, how do I utilize all three channels with the correct receiver? One channel is esc, the other sevo, and the third? How do you control it?
Perhaps I'm just terribly discombobulated here. Maybe the extra channel(s) on the receiver is/are for things like lights and fans, and the TQ-3 just lets you drive with others by switching the channel.
