RE: GX45vs.DA50vs.BME50
DO NOT BUY THAT PLANE! I had 2 and they were the biggest piles of crap.Covering will come off in flight , all the hardware is total crap , it weighs WAY too much for the size it is and its too small for a 50cc gasser .Check out cheif aircraft they have some plane/engine combos for 50 cc planes that are really reasonable.
just my .02
there are much better planes to spend your money on
