I just installed a moosecan muffler on my OS 40FP. I all I did so far for tuning was cut the back 1.5" of the header and then build me a moosecan for it. I am using an 11x3APC prop. OS "3" plug, and byron 15/16 fuel. I am peaking out in RPM range in the low 12's. I have it set to fly at 12,000 RPM.

I don't remember what was tacking w/ the stock muffler because it has been a while since I ran it. Are my RPMs close to what everybody else is getting or am I was off. i was hoping to get around 14,000.

I don't know the demision of the can. But it's pretty small. I will get them this afternoon.

But I did fly it on my 3.5lb menace. And it had a good pull out of a hover, But I am looking for it to shoot out of a hover. But it was windy, and I did't get to hover much with it.

Can you tell me how my 40fp is compairing to yours w/ the moosecan.
