GP j3 cub ARF engine size
To you guys or gals that have the Great Planes j3 cub arf 81" I got one coming soon, just thinkin about the engine size They call for a 70 4 stroke as the top of the requirements, I just happen to have a YS 91 yz that needs a new home. Will the YS be on the overkill side?? I am planning on putting on floats next spring . Give me your thoughts I can take it
