I was getting an occillating harmonic while in flight until I installed some of that thin(but relatively heavy) sound dampening that sticks to the sheet metal panels on the inside of the cockpit. It quieted the cockpit down immensely. This in an RV-4.

I know it's not all that exciting to some, but today I installed the tailwheel chains and bled the brakes, then took that milestone, the first TAXI TEST!!

Although the throttle response was a little notchy, there were no stalls or trouble with RPM control. I had some lean spots and some rich ones too, but nothing that prevented the engine from obeying throttle commands.

The RV-8 rolled along sweetly, steering and braking like a doll.

There are some funny harmonics in the airframe at some various low engine speeds, not suprising, considering the aircraft was intended to be powered by a Lycoming.

I have a bunch of parts yet to install and adjust, but the pile keeps getting smaller!
