[:-]Hi guys, I have a few questions that I've come up with and I hope you can help answer them:

1) What does an in flight needle valve mixture control do and should I use one on my DF?

2) What is the best method to make scale panel lines on a fiberglass fuse?

3) What tuned pipe have you guys had the best success with using a O.S.91, and Dynamax fan?

Thanx. I appreciate the input.[8D]
