RE: Butterfly Conversion
I still fly mine often. When first built, (five years ago), it had a Master Airscrew brushed 05 with a 3:1 gearbox, 12X8 folder and a 7 cell 2400 nicad and flew beautifully at 64 oz.
About 3 years ago I installed an AXI 2826/12 and a 3 cell 4000 lipo and lost 8 oz. of weight but now flys forever. Like Chris said, get out the lawn chair and relax.
