I was planing on buying one of these SPE 43's to put in a 1/3 scale Great Planes Pitts I looked a long time for one of these pitts. Its discontinued so it wasnt easy. I feel this engine will fit in the cowelling without doing to much more cutting of the cowelling. The original owner of this plane had a 160 or 180 glow motor in it. I am a gas guy and i wont buy a large glow motor due to the cost of glow fuel and the amount of flying I like to do. If I understand all this info correctly the US dealer is Cermark? Are all the buggs worked out yet? God knows Ive had my share of buggy motors.
