Thanks Matt for the reply. The plane in question is the smaller one, 53" span? There is a big thread at RCG about this plane and yes, many builds are a bit on the porky side. Most of the builds are from 3.5 to over 5lbs. Hopefully we'll come up somewhere in between. Most of the builders are using dual batteries we're going to try and do it with a single 3500 - 4000mah 3 cell. I'll check into the UBECs you mentioned. You say it uses the main battery for power? Does it plug in line with the ESC? I am still a bit confused. Thanks again for your time.
