Had the propeller repitched. It was a 74X61 but went to 72X68. The engine would rev over redline in level flight at 61 inches of pitch. Way over redline. Now in level flight it might go over buy about 20 rpm at 2720. Manage to pick up 20 mph in full throttle level flight. Wheel pants and gear leg fairings on the main gear gave a 10 mph speed boost. So, we have gone from 150 mph to 180 mph. One quick little bird.
