Thanks guys. I have a supertiger 61 which should do the trick.
I do have an older KB 7.5 sport engine a front card and a rear exhaust and tuned pipe. It's going into a Diamond Dust and possible up the rear of a Combat Models F-16N as a pusher. It's perfect to bury the pipe and hide the exhaut.
FYI... a few of my other projects
