I am working on an enlarged Kaos that will have a Saito 180 FS engine. The original design used no right thrust for a .60 2 stroke. Would including 1.5 or 2 deg of right thrust be advisable with the larger/heavier props?

Thanks,

You Bet. I'd try at least 2 degrees to start with and go from there. For reference, I'm flying a Focus with a 1.2 Bully on it using an APC 16X10 prop, and the 3 1/2 degrees of prescribed thrust angle seems just about right. Just make sure you mount the engine so that you can change the angle easily, as you may also want to add some down thrust.
