LANDING GEAR INSTALLATION

107. Attach the landing gear mounts to the fuselage using two

M4 x 20 socket head cap screws for each landing gear

mount. Place a drop of thread lock on each screw before their

installation. Attach all four mounts.

108. Attach the landing gear to the mount using two M3 x 15

socket head cap screws, four M3 washers and an M3 locknut.

109. Repeat the previous step for the remaining landing gear.

110. Attach the shock support brace to the landing gear mounts

using two M3 x 15 socket head cap screws, four M3 washers

and two M3 lock nuts.

112. Attach the shocks to the landing gear using two M3 x 25

socket head cap screws, four M3 washers and two M3 lock

nuts.

113. Use a ﬁ le to make two ﬂ at areas that are 1 inch (25mm) in

length on the end of the axle. Make sure the ﬂ at areas are

opposite each other.

114. Apply a drop of light machine oil on the axle. Slide the axle

into the wheel.

115. Slide the axle into the landing gear. Secure the axle by

tightening an M3 x 3 setscrew on each of the ﬂ at areas. Make

sure the wheel can spin freely when installed. Repeat the

previous steps for the remaining wheel.

111. Attach the shocks to the shock support brace using two M3

x 15 socket head cap screws, four M3 washers and two M3

lock nuts.

 The shocks will not be able to be compressed by

hand. If so, the the spring rate and tension strength

of the shock would be too weak to support the

landing loads of a model of this size and weight.
