RE: A .60 on a Four Star 40?
Guys, I stand corrected. I skipped right over the"FP" part of it.
You may be correct. It may be just about right in line with the 50SX. There is no harm in trying. He's already had one so he knows what the plane can do.
That's like the guy at our club last year screwed a Saito 120 into a H9 Twist. No that "WAS" definitely overpowered. On the second flight, it loosened the firewall even after pinning it 2 times per side. After he first started it he had the idle a little higher than normal and he turned his back just long enough to allow the plane to start taxiing out to the runway on it's own. He found out on the maiden that landing it was not gonna happen as long as the engine was running.
