Anyone heard anything about this pipe yet?

Curtis flew his new Muscle Pipe Muffler at the US Nationals. It is quiet a bit different than the previous Muscle Pipe. It seemed to perform well for him. To me it looks like a KSJ Muffler on steriods.
It is a direct bolt on canister type muffler. The front 3 or 4 inches of the muffer/pipe is about 2 inches in diameter. The back 4 or 5 inches of the muffler /pipe is about 3 .5 inches in diameter. It seemed to preform well for him turning 1850 in a hover and 1800 in aerobatics on a 7.6 ratio with his OS 91 and pimp setup. The set was really quiet also.

Thanks David for the update, I heard he was using a governor to any info on that?

I didn't ask him if he was back to using a governor. I know he used one a few years ago. It was one that his dad had designed for him since JR does not have a governor. JR produced a governor for a few months but I think they never really sold any here in the US.

I talked to Curtis and asked about the use of a governor.He told me that he only used the governor for the Hovering maneuvers and turned it off for the aerobatics. His need Muscle pipe will be out in August.

I've noticed that the old Muscle Pipe improved the fuel economy of the OS 50 I've got it on, I wonder if the new pipes will do the same for the 91 sized engines?

Curtis may be sending RCU one , so will see how well it works.

Here's a pic -

is Curtis using the MP2 with OS90? Did he have any engine work on the 90? I heard that his 60 was modified, somewhat.

Is it the same as the one, he has out now?

Damn it's ugly!

Agreed! It sure is ugly.

I'll second that
