 Step 1
The engine box comes predrilled for the DA
100L and the blind nuts have been installed.
Use the standoffs provided in the kit to mount
the engine but go over the standoffs with thin
CA first. Then mount the engine temporarily
to mark the hole for your throttle rod. Mount
the throttle servo so the output shaft is
towards the aft of the aircraft. Drill through the
marked hole. Goal is to have a straight shot
at the servo arm. It has to pass through the
tri-stock and the balsa sheeting. Approximate
measurement is shown in the pictures below.
Use the rod and clevis provided in the kit for
the engine throttle arm and a Du-Bro 4-40
E/Z connector on the arm side or a Z-bend.
Remount the engine, make sure to use
threadlock on the bolts.
