Do exhaust tubes work??
OK, I finally got to the point where I can land consistantly (yes, far away from people or houses), but I'm getting tired of spending 30 minutes a night cleaning oil off the side of my airplane. I saw these "tubes" at the hobby store that are supposed to attach to the muffler, and I assume then be routed so as to direct the exhaust and oil residue away from the aircraft. I envisioned running one inside the fuselage and out the back. While at the hobby store, someone pointed out that they could cause back-pressure and significantly impact engine performance.
Has anyone had any luck with these, or have any other suggeestions? I've tried rotating the muffler at different angles, but still get fuel everywhere during maneuvers. Is this just a "fact of life" in the RC airplane world?
P.S., why does so much fuel make it out the exhaust even when leaned down? Maybe I'm still running too rich.
Thanks,
Mayday
