I won my magic extra at the polar bear flyin New Year's Day
started with a mag 46 flew pretty well then
Installed a saito 56 a couple weeks later with a12.25-3.75 apc
moved the c.g.to 4.5 inches flies great now,hovers at three-quarters throttle.
The only thing left is a little right thrust and lots of practice for the fun stuff

or maybe 72?
