lov2flyrc -> Ys 45 Rear Exhaust In Cbm F16n (4/9/2002 1:53:05 AM)
|
Use a mac pipe and header, the off-set one and use it inverted. I tuned the Mac pipe on a test stand. On the pipe you need to pinch off the end of the pipe. Got a brass pipe about 6" long and the same diameter as the end I pinched off, drilled a hole on an angle (towards the pinched off end) at the largest part of the pipe, inserted the brass about an inch and sealed the hole with a mixture of epoxy and carbon fiber chop. Now the outlet of the tuned pipe is facing the engine and exhaust goes through the prop (just like a byron pipe). Use a tuned pipe mount on a dowel the proper length to support the pipe inside the fuse. You will need to cut an access hatch between the dorsal fins to install the mount and attach the pipe to the mount.
