Thanks for the heads up, both of you. I have only flown it once and that was with the MDS 1.48 on it. I was flying it for the owner and also deciding if I wanted to swap. I was going to give him my pitts with the YS FZ 1.20 but after I read up on the MDS 1.48 I decided to keep my engine and let him keep his. I guess I am going with the Saito 1.50. Having the Twist and the U Can Do with the 1.20 should keep me happy on the 3D side.
