Ok I am building the four star 60 and have run across a question. I am getting ready to place my engine on the firewall following the vertical and horizontal thrust lines. Problem is when I center the engine both thrust lines the throttle arm sits above the firewall. So my question is, is it ok to lower the horizontal thrust line to fit the engine on the firewall and keep the vertical thrust line centered. Or do I need a smaller engine? Thanks.
