RE: GP Super Stearman
Robert,
Your Super Stearman looked great in the video. I didn't know it had clear tape all over it! I couldn't imagine why you wanted to re-cover it. That's a good reason.
I would think the 20CCs would be just just fine, as the plane is designed to fly well with a 1.20. The original Stearman was a military trainer, with a much smaller engine than the Super Stearman, and it had plenty of power. The Super Stearman was fitted with a 450 HP engine for hauling spray-rigs for crop-dusting, and soon was used for airshows and aerobatics. No doubt, your 20CC engine would be right in the middle of the range between the two, maybe a tad on the upper end. Plenty of power. Lots of wing on this bird, too, something like 1440 sq. inches.
Truthfully, the 30CC engines fit into the plane, but the kind of speeds it can put out just don't look right at full throttle. I don't think the full-scale version had anywhere NEAR unlimited vertical. And I don't know about you, but I didn't go through all the trouble of building an old-time Stearman model with a plan to fly it at speeds that don't look real or pretty in the air.
Looking forward to more videos of yours. I'm hoping to get a few of mine out there as well.
