3W Engine Rebuilding
Hey Diablo.
I can vouch for Gerhard's knowledge of the 3W's. I had a 150 that didn't run right from the git go, but was crashed first flight so just figured it was damaged. Gerhard found manufacturing error, and hense fixed it under warranty, as the crash had no effect on it.
One side of the crankcase was a smidgen thicker than the other creating poor compression on the shorter side!!! He used the good parts and created a very strong engine that I am extremely happy with.
I wouldn't hesitate to send any of my 3W engines to him. He has also been extremely easy to talk to and takes the time to listen and deal with the cause of your call.
