Although the G20 is marketed as a possible replacement for 60 size planes, it is really too heavy at 43oz for most 60 size planes. There was one person that did a H9 Hellcat with one, but that also isn't an aerobatic type. If I remember right, the G20 produces about 1.7 HP, which is less then a comparable 1.00 glow motor(saito 1.00 makes 1.8HP). If you want to sue this motor, a 90 size plane would be better bet.
