I just finished breaking in a Medallion .049 for my Sky Sport stunter. The Tornado 3 blade 6x3 hits the rpm target I want. Sadly, I only have one of them.
Anyone have a source or some to sell?
The engine has a TD piston and cylinder and extra fin plug retainer for Merlin plugs. It turned the 5x3 at 18,000 and the 6x3 at just over 15,000. 15k is where I want to be.
