RE: Great Planes 25% Pitts M-12s 3D
Mine is 19 pounds on a DA-50 and it will NOT hold a hover (literally falls tail-first out of the sky). This is a new DA-50 on a 22x8 Menz prop and Lawnboy ashless 32:1 (the recommended break-in stuff). It seems to fly fairly "scale". If you want a plane that flies fairly scale, stick a DA-50 in it and you'll like it. If you want a 3D plane or anything more than scale, get a larger motor. By the way, I'm also running a carbon fiber spinner and left the wheel pants off, so that 19 pounds should be fairly close to what you'll get as well. I have about 3 gallons run through my motor thus far and I'm hoping that when I switch to synthetic and a 23" prop, it will perform better.
Mine is probably going to be put up for sale soon. Looks great, but not really what I was hoping for.
