Small diameter props and large spinners
Hi Guys,
I've got a question for you go fast types. Our club is having a for-fun pylon race in which we have to use 40 size war birds and .55 max motors. I have selected to use a Spitfire with a Jett SJ50. A 2 3/4" spinner mates perfectly with the front of the fuse and the SJ50 seems happiest with a 9" prop so I'm wondering if using a large diameter spinner causes any loss of thrust with these smaller diameter props.
Along the same line of thinking, I may run a Corsair as well with a Magnum .52XLS. I'm wondering if using a large spinner might help divert some of the thrust around the large round cowl on the Corsair.
Any and all thoughts on this matter will be quite welcome.
Blessings, Terry
