I put a Thunder tiger 120 2c in mine swinging a 15x8 APC prop I'm just a bit over 12.5 Lbs , was thinking maybe going to a DLE 30 for a little extra power if need be , did you balance at 145mm like the manual states ?

funny thing is I haven't completed or flown mine, some minor details that could probably be done at pre flight , however I already have plans for another 120 CMP Zero LOL
