Well Tower does list it as such, here are the specs as listed on site. I don't think with a 1000' to runout, I could try to get this bird in the air with a .60 sized motor up frount. LOL.
The airplane will fly very nicely with a .60-.61 two-stroke engine if you keep the weight withing the recommended range. The reason many people have difficulties is that they get the model much too heavy. Do that, and your airspeed requirements for takeoff and landings go up, and you therefore need more power to keep the takeoff distance down to a more reasonable number.
The model WAS flown with a .61-size engine during its testing, at the maximum design weigh of 10.5 pounds. Lighter is better.
