Today I went to the lhs and bought a 2 1/4 inch spinner and an apc 11 by 5 prop. I just put it on my h9 arrow. I was wondering if any one has any experiance with this combo. I have only gotten three flights on it and I have a feeling I am setting myself up for disaster.(This new prop has about an inch less ground clearance than the included 3 blade)I was also thinking about removing the flywheel thats on the engine. If anyone has any suggestions on this setup please feel welcome to reply!
