Hello All,

I am completing a Bud Nosen Citabria my father started about 15 years ago. With today's engines, fuel choices, and power applications, the opportunities are limitless as to what
"CAN" be done and what I wish to do.

~cutting to the chase~ I wish to put a 30cc gasser on the aircraft. Albeit, in order to use the aforementioned engine, thecenterline of engine will place the prop shaft at 1/4" above the thrustline of the plans in order to mount the engine within the cowling and aligning the propshaft cut out.

My delima: How catastrophic would this be? The plans also call for (0) zero degree down and/or (0)zero degreeright thrust.

Thank you for your time,
Scott
