I put mine together with the supplied dowels. The two upper fuse openings are for the elevators and the lower left is for rudder. I followed the manual for assembling the elevator and rudder dowels with 2-56 rods. The elevator dowel will be a "Y" as there is a control horn on each elevator half. Worked out fine for me. Go back and re-read the steps outlined for the pushrod assemblies. Reading them slowly a second (or third) time often makes things a little clearer.
