I dont understand why you guys would pick the Zenoah G62 for this bird. It seems to me a good small ignition gasser would be lighter and pull much stronger. Such as a MVVS 2.15 35cc or a BME 44 or ZDZ 40 etc. The G62 weighs in @ 82 oz's, what kind of tail weight is required to balance this beast? The MVVS 2.15 weighs in @ 55 oz's, the ZDZ 52 (I think), BME 44 weighs @ 43oz's. Not trying to knock any of you just curious, as I am looking for a larger Bipe.
