Great Planes ESP6 Easy Sport 60 - GPMA0152 - Manual (Page 46)

Clevis and Retainer
D 9. Slide a silicone retainer onto the rear end of a
nylon clevis. Thread the nylon clevis 13 revolutions onto
a 36" wire pushrod (threaded on one end). With the rear
of the model facing you, slide the pushrod into the
right hand pushrod tube until the clevis pin is even with
the elevator hinge line. D 11. Assemble a second wire pushrod as you did in
step 8. Insert this pushrod into the left hand pushrod
tube. Align and mount the control horn 1/2" above the
rudder base as you did in step 9.
Fuelproofing may be done after covering.
D Fuelproof any external exposed wood (i.e. landing
gear plate, etc.).
CORRECT INCORRECT
D 10. Cut the nut plate from a nylon control horn.
Position the horn in line with the clevis (approximately
5/16" from the fuse) with the clevis holes centered on the
hinge line. Mark and drill the mounting holes with a 3/32"
bit. Attach the control horn to the elevator with two 2-56
x 5/8" screws fastened to the nut plate on the opposite
side of the elevator.
SPECIAL NOTE: Do not confuse this procedure with
"checking the C.G." or "balancing the airplane fore
and aft." That very important step will be covered
later in the manual.
Now that you have the basic airframe nearly
completed, this is a good time to balance the airplane
laterally (side-to-side). Here is how to do it:
D 1. Temporarily attach the wing and engine (with
muffler) to the fuselage.
D 2. With the wing level, lift the model by the engine
propeller shaft and the fin post (this may require two
people). Do this several times.
D 3. If one wing always drops when you lift the model, it
means that side is heavy. Balance the airplane by gluing
weight to the other wing tip.
NOTE: An airplane that has been laterally balanced
will track better in loops and other maneuvers.
