So I had a batch of anodizing to run so I threw some of my parts in while I was at it. This is the finished Sniper DR(disk rotor) .049. This is my second proto using my new milling machine. This engine was happy making 18,200 rpm on a black Cox 5x3 on 20%nitro. It will turn a Cox black 6x3 at 15,000. It is a very easy engine to start and I was hand flipping it 90% of the time. This was in 30 degree temps while it was snowing/sleeting here yesterday.

Later,
Tim
