Ok, I can understand the concept of using your finger to check engine temperature. But everyone has different tolerances to heat, so its not an accurate way to check it.
Is there an actual temperature range that a heli engine should operate at?
My OS 50 Hyper just runs hot. If I richen it up just one click, it just doesn't run well. I can even see fuel spraying out the exhaust but I can still only hold my finger on the backplate for 1, maybe 2 seconds.
Try running it leaner with a little lower throttle curves. Say 95, 70, 50, 70, 95 instead of 100, 75, 50, 75, 100
