61 FX / Power masters 15% nitro with a Davis Quite Pipe...

11,100 Running an 12X10 pattern prop. This puts my OS 91 FX to shame ;-)

The Davis pipe is about 130 bucks, and not as good as the MAC. I would simply order a MAC pipe and header. 60 bucks, and you are screaming. If you are are trying to quite it down, go with the Macs quite pipe... both are good choices. Tower has them.

-----Or get a Performance Plus tuned muffler! You will pick up 500 -
1500 RPM, depending on the prop you are turning, I can guarantee it! Mine will turn a Scimitar 12-6 at 14k and an APC 11-7 at 15500! This on Wildcat Plus 15%. In the air it sounds like it picks up quite a few more revs.

ok... that lasted one day
 

28 bucks... bocca bearings... blew the front bearing ;-)

There isn't a performance pipe available for my Rossi .60. Actually I got this engine from Morris years ago and used it for about a dozen flights. I have the Rossi pipe, but was hoping for something a bit lighter. Any ideas Ray? Thanks_bob

Did you talk to Dave? I thought he made an adapter to mount the UT onto Rossi's.
Check with Jett also.
