Thanks for all of the responses. I'm not sure yet what I will do but it seems that buying the Hitech Flash 5 would be the best route. I am really confused about battery packs and amps and how to determine the BEC size required. Any suggestions for some good web sites that explane this information in simple terms? Btw, have any of you dealt with Raidon Tech? They seem to offer several 3 channel planes (mostly sailplanes) at really low prices.
