RE: OS .15 old style
I had enough trouble finding a 7-5 anything around here. No one stocks small props any more. I pick stuff up on trips to the US. Since then I have put in an FP .15 figuring it would be faster with the schneurle porting, but I can't tell the difference. Control line is better, you can time things to find out the speed. The Scamp is just a toy anyway.
