Crash,
I just bought a Magnum 91 four-stroke. It runs great and I'll be putting it in my Great Planes AT-6.
I recently heard that Magnum has cleaned up it's quality act and their engines are much more reliable these days.
I'll let you know after I've flown this one a few dozen times.
Aloha,

Cool. If ya remember, let me know how it does. I've had 2 I used and it was a serious PITA to tune without a deadstick landing.
