I'm using a YS 120 taken from a plan whose expiration date was this past spring. That plane had plug-in wings, so an underbelly pipe was not an issue. With the Venus, does anyone have an under-belly pipe that they can detach from the wing in order to remove the wing? I could go out the side with it, but I can't find a header to go from the side of the engine in that direction. Central Hobbies sells a 90 degree stack, but it's much smaller than the pipe. Maybe there is an adaptor that can go from the end of the stack at one diameter, to the end of the tube at a larger diameter?
