To give you an idea, The GP...
PT-20 has a 52 3/4" wing.
PT-40 has a 60" wing
PT-60 has a 71" wing
Is it THAT much more stable? It depends on your definition of "THAT" (I know, I sound like Bill Clinton) but it WILL be more stable much the way a hawk is more stable than a housefly. How much is a relative term. I would say that if you intend to stay with 60 powered planes, go with the 60 size trainer so the engine will move up with you. Or get a 91 4-stroke if that's what you want to move up to. If you want to eventually fly a 91 4 stroke, but can't afford one right now, but you have a 40 2 stroke, then don't waste your money buying a 60. Learn on a 40 trainer and save your money for later.
Do I have you sufficiently confused now? LOL
Don't forget, An LT-40 has a 70 inch wingspan and 900 sq.in. of wing area. That's as big as most 60 size trainers. To boot ,it flies beautifully.
