I think the "BEST" person to ask this question to is not all of us here, we are all more than willing to share our experiences, advice and oppions, but really the best person is your instructor. 1] he'll help you choose something he knows how to program, adjust and probably have a buddy box and trainer cords for. That saves you from having to supply him with the training aids for your plane. 2] he can advice you as to what channels to stay away from. We have approx 5 that get "HIT" alot. 3] by using what is common for your flying site often somebody has a spare servo,extension or what ever, so you can keep flying instead of packing up to run to the L.H.S. We often loan or sell parts where we fly.
