RE: OS 55 & Red Jett muffler
I am waiting for some longer screws with inch threads for my muffler extension and will test my OS 55. I have an Ultrathust muffler, not a Jett.
I'm not overly impressed with the power of mine running the stock muffler/baffle, but it sure runs nice. looooow idle, smooooth transition and sips fuel.
I want to see if I can emulate the numbers that T-34 gave me, I did notice he can't fly very long, he sucks his tank dry in 7 minutes or so.
No free lunch for power.
Food for thought; do you know how well a YS-45 SE runs with the stock muffler? Well it runs like cr@p. And it's a screamer on a pipe/tuned muffler.
