7. Thread a clevis 15 full turns onto a 2-56 x 12" [152mm]
threaded one end pushrod. Install a clevis retainer onto the
clevis. Connect a control horn to the clevis. Place the control
horn on the aileron as shown above. The pushrod should be
at 90 degrees from the trailing edge of the wing. Mark the
holes for the control horn and also where the pushrod meets
the servo arm.
❏
8. Drill 1/16" [1.6mm] holes where the control horn
screws need to be. Wick some thin CA into the holes and
install the control horn in place with two #2 x 1/2" [13mm]
screws and a backplate. Also, bend the wire 90 degrees
where the wire pushrod meets the servo arm and install a
FasLink. Cut the excess wire 1/16" [1.6mm] away from the
FasLink.
Note: In the installation shown, the engine installed is an
O.S.
® .70 4-Stroke. A 2-stroke engine can be installed the
same way as the instruction model engine. The
recommended position to install the engine is inverted,
although if you wish, you may install it in a different position.

1. Locate the left and right halves of the engine mount
and cut out the spreader bars.

2. Install the engine mount to the firewall (F1) with four
6-32 x 1" [25mm] SHCS, four #6 Washers and four #6 lock
washers. Before you tighten the SHCS, make sure that the
mount is the width you need for your engine and that it is
centered with the fuel line hole on the firewall (F1). Use
some Great Planes Pro Threadlocker on the engine mount
bolts and tighten the SHCS.
