I was using the heli muffler for the TT engine, and it worked great. I also tried a mousse can, but the can volume of the can was too large. It had a funky transition, and flame out, especially when vertical. I've got a smaller can for it, but havent put it on a model to test with (can you say Fat Free Taco )

If you run the 32 or 36, then you can run a 4 oz tank in place of the 6 oz, and save a little bit of loaded weight. Also put your battery either under the radio tray, or cut a hatch in the back of the plane to put it in the back half of the fuse.

Oh yeah, I got my TT36 at a swap meet practically NIB (was taken off a raptor to be replaced with a 50) for $25.00. The guy didnt realize you had to tighten the screw that holds the carb onto the engine to get it to run.........
