You know, planes do have wings to keep 'em in the air. I ave a GP super stearman I'm building, and I'll be flying it with a Saito 1.80. Another guy at my field has a GP pt-17 with an OS 1.20 four stroke. Both of these planes come in close to 15 lbs. That os seemed to fly the PT well... It jumped off the rough grass field after only 30-40 ft. and climbed out at a 30 degree angle. If the 2300 has more power than a saito 1.50, I don't see a problem if it's proped right. Am I missing something??
