RE: GP Super Stearman
I wonder about the G26 as compared to the 1.20 w pump.
I have a G26 in a 1/4 Taylorcraft and while it's a fantastic little engine, it doesn't quite have the power that my mates pumped 1.20 has in the same aircraft but weighs substantially more.
The G26 is only 1.4cu in and small gassers seldom have the same power as comparable volume glow motors.
Anyhow, I suspect it will fly the Stearman nicely but from the photos above, it looks like some cutting will have to be done.
I also wonder about cooling. Don't gas engines need better cooling than glow engines?
Will you be installing the dummy cylinders?
Keep these photos coming. I'm determined that I will be buying one of these planes. Beautiful plane!!
