Thanks again joe, As for the shem plate.. it is 1/16" but is removable. If it is too much then I will reduce to the size of 1 washer.... My plan at least..... Also, I keep hearing all the talk about keeping the plane under 8 pounds. I am not sure how to manage that seeing how I am only putting the bare essentials on the plane and have no idea to reduce the weight if needed. Should I weigh what I have and just lay the items that I have not finished on the plane to get a rough draft weight? AS for the engine.. It is a Saito 125. I have no idea where it ranks on the weight scale.. I have already mounted the engine in the motor mounts so if it is the wrong position I guess I will have to buy new mounts... How do I know how far out to mount the engine? The factory specs say the engine weighs 24.69 oz total weight with muffler.... AS i mentioned.. i mounted it 5 7/8" from firewall on left side and the right side is 1/6" shorter.. Will this be ok? How do I tell??
