Probably a combination of a low idle and an inbalanced prop can be the culprit in your case.
DS.
The main problem is that it has horrible vibration throughout the entire rpm range.
As you can tell, I'm fairly new to rc flight. I have some expierence with electirc flight, but this is my first glow burning plane.
I don't have any LHS's within 100 miles of me and I don't own a prop balancer. Is their any way to balance a prop just using "around the house" stuff?
Also, I fly at over 7000ft. that's the reason for the big engine. (but who doesn't like a little extra juce anyways)
Thanks again for your help and advice
