Hey again! Im wondering if there is a list of engines that go great with 60 size, 9LB-12LB Aircraft
My experience is that 10 to 12 pound airplanes will require a .90 size engine. A 60-size airplane generally should not weigh 9 pounds. However a .75 will fly a 9-pound airplane. A 1.20 engine is usually used in 14 to 15 pound airplanes.

I think these might be a tad low depending on flying styles i have a ~12 pound extra that has a moki 2.1 in it (2 stroke glow ~ 4.5 hp)
