Kirk, that is interesting. I have never seen Open A flown. SSC and Open B still remain the favorites here in Texas. I bet a .15 does like that small prop. BTW, the new Magnum .15 is a vast improvement over the old one, huh? Easily the equal of the LA .15, and is not too far off the performance of the CVA .15. And on only 15% nitro, too.
