by the servo manufacturer.

LANDING GEAR AND WHEEL PANTS:

24) The landing gear assembly, complete with wheels and

wheel pants is now assembled and mounted to the fuselage. We
suggest you use Loctite

"Blue" non-permanent thread locking

compound on all bolts used in this assembly. From your parts
bags, locate the two 2-1/2" dia. main wheels, the two M4 x 40mm
steel wheel axle bolts, four 4mm axle lock nuts, and two 4mm hex
nuts.

Insert the M4 x 40mm axle bolts into the wheels and thread one of
the 4mm lock nuts onto the bolt until there is about 1/32" side play
for the wheel. Thread the 4mm hex nut down on the lock nut to act
as a spacer, and add a 4mm lock washer. Insert this assembly into
the large hole at the bottom of the aluminum landing gear and
secure with the other 4mm lock nut.

25) Note that there is a front and rear edge to the aluminum

landing gear - the legs are tapered. When the landing gear is
placed upside down on a flat surface, gear legs up, the leading
edge (front) is 90

On the servo end of the cable, slide one of the copper swage tubes
onto the end of one of the cables. Then insert the end of the cable
through the small hole in the end of a threaded rigging coupler, 
giving yourself about 2"-3" of cable to work with. Loop the short
end of the cable back and run it back through the copper swage
tube. Pull the swage tube up to about 1/2" away from the rigging
coupler, and use a pair of pliers or a crimping tool to squeeze the
copper tube tightly over the cable, locking it in place. Cut off the
excess at the short end of the cable and wick one drop of thin CA
into the swage tube to help lock the cable in position. Repeat this
process to make the same connection with the remaining piece of
cable.

Attach the rigging couplers to the servo output arm as shown in the
photo. Make very sure that the rudder cables do not cross over
each other in the rear of the fuselage.

Each cable should run

straight from each side of the servo output arm to the exit tubes at
the rear of the fuselage. Pull slack out of the cables and retape
them at the rear of the fuselage. Note that the rudder ends of the
cables will be assembled after the fin and rudder are glued in place
on the fuselage.

23) Plug the 12" extension cable to the elevator servo, secure

the plug with heat shrink tube or tape and thread the cable into the
