RE: GP Super Stearman
I got mine a couple days ago but it will have to sit on the shelf while I complete my current project. I'm restoring a pair of used Kyosho Stearmans for me and my brother to fly. Should have them in the air late next week or early the week after.
I also just bought a Cermark Pitts which I plan to put a G26 in. I think I'll do the GP Stearman first though. I'll put the first G26 in it and get another one for the Pitts.
Ralph Cunningham says the G26 will produce over 17 lbs of thrust. In a 15 lb plane, that should give pretty good performance for someone who isn't into 3-d.
