Control surface/servo installation cont. 

A piece of 1/8”(3mm) plastic tube 
can be used as a cable guide.  Glue 
the tube to the fuse and run the 
cable.  Use two tension adjusters to 
attach the cables to the servo control 
arm.  Note we are using the inside 
holes for the cables.  The two 
springs in the photo are used to 
control our tail wheel assembly.   

Wing assembly (Landing Gear) 

We’ll start with the installation of the 
landing gear.  Please note our proto 
type did not have the wheel wells 
pre-installed at the time this manual 
was written.  Assemble of the strut 
requires only installation of the 
wheel. Temporarily install the axle 
into the wheel and onto the strut.  It 
may be necessary to install some 
spacers for proper wheel clearance.  
Once satisfied mark the axle, remove 
and cut to length.  Grind a flat spot 
on the axle for the set screw and re-
install.  The strut can now be 
installed into the retract mechanism.  
Wheel alignment can be done with 
the wings Installed on the fuse. 

The mounts are pre-installed and 
only require drilling the holes for the 
retract unit.  It may also be 
necessary to remove a small amount 
of material from the former to allow 
clearance for the strut.  Note the 
small cutout in the LG mount right 
behind the retract to allow the air line 
to pass.  The mechanism is mounted 
as far outboard as it will go in the 
hole.  When satisfied with the fit, 
mount the retract unit with 8, 6-32 wood or sheet metal screws.
