A Gentle Lady is not a hand launch glider. You use either high-start or a power pod to get it into the air. You'd be lucky to get it 50 feet up on a hand launch.

I have some different thoughts about radios. If you're on a budget, a 4-channel is the only way to go. You won't be using the extra channels, and a non-computer 6-channel radio is a waste of money. The most common use of more than 4 channels is for a 2-servo wing. That certainly works best with a computer radio. You won't be adding retracts to a trainer, nor will you be adding flaps. I've got a buddy that put a bomb-drop on his. You don't need an extra channel for that, as you can just connect it to the rudder. If money is tight, don't buy a basic 6-channel. If money isn't a problem, buy a computer 6-channel.
