Thanks for the replys.

Will thanks for the PM yesterday really appreciate your advice. The pipe is the Hatori 605 pipe and matching header for the MK Beetle.

I know you can go slow and take a bit off at a time, but its nice to have a reference (like with the MACS charts) however under the normal hatori pattern setup for this motor (ie; 605 pipe, 11x7 - 11x8 apc prop, 15-20 % nitro, etc....) there has to be a ton of experience on this motor. Will's advice is the type I was looking for reference.

Beetle is the classic that I purchased last year from RustyB. Great guy and a great plane - looking forward to getting her finally going in the next week or so.
