Default RE: MK Skystar - build started

Here's an update after countless trim and practice flights and more than 2 gallons of fuel through the Webra.

The Sky Star is a fine flier. There are some flying characteristics that I'm having trouble getting used to in rolls but that's personal taste. It flies great and holds the line very nicely in all attitudes.

The Webra is a different story entirely. It keeps making my life miserable. What I thought were break-in quirks are now full blown contest-wrecking poor running characteristics. It started leaning out sometimes when I flew and I found it was overheating. I wasn't even using the belly pan on the plane at the time. Plugs started to get whacked more often that they should (OS #8's) and now it quit on me during a contest flight, probably overheated again. The bearings sound... not great and would you belive RPM is dropping all the time. This week I got 9500 on the 12x11. That's down 1.000 rpm from the first days test! Today it would not even run properly on a 13x9. I have left things well alone for the break in but it appears I should not have. I have found it to be rich on low mid-range so the low speed needle will be turned leaner and I have been told my pipe setup, which is a Hatori 700 (43 cm) and the header, 24 cm which is about 65 cm from plug to pipe's high point is too much - Experts tell me they ran their O.S Hanno's on 55-60 cm pipe length. Bring forth the saw, this header is about to be chopped!
