RE: HANGAR 9 Piper J-3 Cub 40 Conversion
Hi I converted the World Models 1/5th scale clipped wing cub, I used the Axi 4120/14 motor, with a 3700mah 4s1p Shark lipo, the set up was well up on power and got the 8lb model off the ground in about 15 yards. I used a 13x6 apce prop and a Jeti 70 opto esc with a separate powere pack for the radio. I get about 10 minutes with aerobatics thrown in, or 12 with a sedate flight.
