Well i have the tojeiro 140 and the pipe tunnel is inside the plane. so you really need a header and pipe designed for it. Can you say it looks like it was designed with a ys and a hatori pipe and muffler. The build on mine has been pretty fair so far. replacing the wing and stab tubes and the landing gear with carbon ones. same thing with the elevator linkages. The supplied bell crank was real flexible so i replaced it with a MK bellcrank. And am using kevlar pull for the rudder. never used kevlar before. just trying it out hopefully it will work. I flew the smaller Venus fore someone and it flew real nice. infact i bought the venus and the venus II now i just have'nt gotten either one out of the box yet. Someones earlier comment. about going to the regular pattern site is a good one as there is a tojeiro thread there already.
