Cowl & Spinner Aerodynamic Question

Hey Someone11, where do you fly? I live in Fresno also (Clovis actually) and I usually borrow Buchanen's fields for my gliders or a farmyard for my little electrostreak. Anyways, most spinners I've seen are smaller then the engine's cowling, so I wouldn't worry about it.

I fly at the FRM airfield in Madera. Here's a link to their website: http://frmmember.freeyellow.com/

I flew my skytiger last weekend with a 2-1/4" spinner and it worked fine. The fact that I have a cowl there instead of the "cheeks" made a difference, so I don't believe I have to worry about the size of the spinner lining up with the cowl.

Thanks for your help guys!
