AJ, et all,

I posted this question in the Control Line Forum, but had no responses yet/ Maybe you can help?...

I want to buy an electric power starter for my Super Ringmaster with K&B 19 and K&B 29 engines. The plans show a 2 inch spinner, but I see millions of different spinners on the Brodak and Amazon sites and elsewhere.

Any guidance from you all?? I want the spinner to fit both the plane and the starter "cone"???

Thanks,
aaganz
