OS105 lives again.


The parts for my OS105HZ DRS helicopter engine came in a couple of days ago, and I was so excited about getting started on the rebuild. Man... there was a lot of damage caused by that retaining pin that came out. I had to replace everything in the engine except for the case, crankshaft, and carburetor. Everything else was a complete write off. But.... It`s a brand new engine again, and It`s in the helicopter and ready to go again.

This weekend, I`ll take it out and go through the break in process again and then work on finding the really good tune I had on it before my little oopsie. I even installed the .2mm shim in the head, so I can run 30% nitro if I decide to do so.
