stg61abc, I ran the engine again with a new ST muffler.

Powermaster 5/22 GMA
Rev Up 10x6
14,111 peak
6.33lbs static thrust
1.24hp

Wow! I gained 622rpm. With an APC 10x6 it would probably rev a bit higher still (but, I don't have one).

Thanks for the muffler suggestion! I wonder what it would do on a pipe?

Hey David,

I plan to run this same engine with a Macs 6.5cc muffled pipe and 10x6 and 11x5 props in the spring. I'll report back with some results... 15K on a 10x6!? or maybe 14K on an 11x5?

Cheers, David.
