RE: Super Tigre 91
I think people who can tune and fly Supertiger engnes like Twinman turn out to be the most knowlegable engine guys at the field.
There are two kinds of modelers those you flip the prop and fly and those who twist and grind on the needle valve and are never happy with the way their engines runs.
Good engine guys that you can trust and rely on are far and few between.
