I got mine working well last weekend using the CMDi bar stock AB .45 XT pipe.

That was until the crank broke in half! :blink:

Not a Hydro...but I run a .45 HR in a speedmaster mono. Turning a 450/3 that is detounged. I use the cooper QHP at 9 7/8 inch from center of cylinder to weld on the pipe. I run 40% nitro...runs very well. Just got to figure out how to keep the wet side down and the pointy end forward.

Got any pics of how the OS carb is adapted to the CMB 45HR? that sounds like a cool mod, haven't been terribly impressed with the remote needle set-up that the 45 HR comes with.

Cheers
