I think I have about 1.5oz of lead in the tail....btx, rtx all in the front of the plane. The webras are so light that it takes a little more nose wgt. than other engines in thier class. We also mount inverted with no probs of starting. Some do similar technique as youself. I use forcepts on the carb line so no fuel reaches the needle during fill. Also we found that quick fill fuel valve dont take the g's we put these planes through. All of us switched to fuel dots...much better. I have always used the dot on my large scales, but since we fly "full throttle" with these aresti's, the 16oz fuel just dont last very long, we tried to save a little fill time.

Sounds like ya all are having as much fun as we are. Try the knife edge snap on low rates, start with the first snap at 3ft of the ground then let er' roll up. I bet she'll do at least 10 before she gets outa sight. High speed inverted flat spins are cool too.

later,
