I had A LOT of theese same questions, since I am as NEWBIE as you get to RC. I don't doubt it is a good product, Just that the manuel is EXTREMLY terrible, and the fact that instructions are not avaible for ANYTHING else included in the box..the switch, the charger, DSC, Rx.....and even the silly frequency # display that clips on the antenna. For a Newbie, all this equipment is really new to us. I figured most of it out, but i expect to have a piece of paper that says this does that...this goes here.....
