RE: Hangar 9 Twist 3D
jlank.
The OS 70 would be a great replacement. I have one in my twist right now. I use to have a Saito 80, which also flew it well but I needed the engine for another plane. So I put in the OS-70. I was using a 12 x 3.75 prop and it flies it just fine. Plenty of vertical at just 1/2 throttle. Take off are no problem. I just changed the prop to a 13 x 4W and hope to try it out on Sunday. That is suppose to be a fun fly type prop. I want to see how it flies with that one.
