INSTALL THE FIXED NOSE GEAR
If you will be installing a mechanical or pneumatic nose gear
retract, skip this section.
❏
1. Fit a 5/32" [4mm] wheel collar into the nylon steering
arm aligning the threaded hole in the collar with the hole in
the arm. Loosely thread a 6-32 x 1/4" [6.4mm] SHCS into the
collar. Cut off the outer hole from the steering arm. Install a
screw-lock connector into the outermost remaining hole using
a nylon retainer. Loosely thread a 4-40 x 1/8" [3 mm] SHCS
into the screw-lock connector.
❏
2. Slide the steering arm onto the nose gear wire. Apply
a drop or two of oil to the nose gear wire hole in the engine
mount. Insert the nose gear into the hole and position the
two fl at spots so there is one evenly spaced on each side of
the engine mount rail. Loosely thread a 6-32 set screw into a
5/32" [4mm] wheel collar with thread locking compound. Fit
the wheel collar and set screw onto your hex driver (or allen
key) and slide the collar onto the end of the nose gear wire
as shown. Tighten the set screw against the fl at spot on the
wire. Tighten the SHCS in the steering arm against the other
fl at spot. Ensure that the nose gear rotates freely inside the
engine mount hole and doesn't move up and down.
❏
3. Drill a 3/16" [4.8mm] hole in the fi rewall inline with the
screw-lock connector installed on the steering arm. Cut off
the threads from a 2-56 x 24" [610mm] pushrod. Slide the
pushrod through the screw-lock connector, through the hole
in the fi rewall and up to the rudder servo. Make a 90 degree
bend at the aft end of the pushrod and connect it to the second
inner hole of the rudder servo arm. Secure it with a nylon
FasLink. With the rudder centered, straighten the nose gear
axle and tighten the SHCS in the screw-lock connector. Cut
off the excess pushrod 1/4" [6.4mm] forward of the screw-
lock connector.
❏
4. Install the nose wheel using two 5/32" [4mm] wheel
collars and two 6-32 set screws. As you did with the main
gear, grind fl at spots on the axle for the screws. Use thread
locking compound when tightening the screws and a drop of
oil on the axle for the wheel.
