Status: online 		Yes, but didn't tach it.  8-4 MA worked good in the Sig Scamp, but I think the MA 7-5 was a bit faster.

Status: offline 		why not run a APC 7x5 it will be even faster than the MA. The MA have less pitch than stated..

Status: online 		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.
