Default OS Gemini 300 mated to GP Super Chipmunk

Weight doesn't appear to be of concern due to the inherent tail heavy condition. The question is "Will it fit inside the cowling? I had read somplace on this site that one had used this engine in an Ohio R/C Super Chipmunk. The engine's width is 9.5 inches. It would be a great combination.

I have a spare ohio Rc chipmunk cowl and I'll try to measure for you soon. I don't think it will fit completely but if it did - it would like awesome in the nose.

I'll be waiting for your answer patiently. I don't want to order the plane and rely on wishful thinking. Thank you in advance.

The inside of the cowl measures approx. 7.5" inside. Ironically, the same size as the ohio RC chipmunk.

OK, this answers several questions. Obviously quite a bit of difference. The reference had to have had the cylinders exposed outside the cowl. well, back to the drawing board for a candidate aircraft for this OS 300 engine of mine. Thanks for your help on this matter and Happy Holiday.
