Thanks for the advice everyone. I'm still thinkging..... I'm looking at the Sig Mayhem also. I know it's not an Edge and not near a "PURTY" but the edge would require me to buy another digital servo and costs about $70 more.

The Mayhem needs at least 70 in/oz on the ailerons and elevator and 90 on the rudder. If I went with a 6V battery it would up the power to 83 in/oz @ .15 sec. Would that be close enough? And would I need another charger for the 6V battery?
