hi guys.
I am building my Bobcat and doing some mods to it also. I will post some pictures. As for the exhaust I have the blue silicone tubing coming from the exhaust port and going through the left side of the fuselage and exiting out the bottom of the plane. It is a pretty neat set up. Its only about 3.5 inches long and will not effect the performance at all. I would do it now but I gotta watch Ohio kick some butt.
