RE: Selecting a 6 CH radio, Which one??
Go to the field or the hobby shop and give all the different tx a try. I like the feel of the optic 6, Polk and the Jr Tx. I fly with a neck strap so balance is important to me. What ever you get, make sure you thoroughly go over it ie: range check battery life... It is not hard to find something bad about any radio, so search with a grain of salt. I sugest to buy something you can grow into. Like the optic 6, Futaba's super 6, or 9c better, or the polk tracker 3. Personally I think the futaba looks cheaper than the Hitec optic 6, and the tracker 3 is just ugly but a great value.
Good luck.
