35) 

The tail wheel bracket assembly is attached to the fuselage with two #2 self 

tapping screws which are supplied in the hardware bag. Hold the tail wheel 
assembly in place with the wire firmly touching the rear end of the fuselage. 
Mark the location of the two screw holes and drill with a 1/16” drill bit. Simply 
attach the bracket with the two screws. 

NOTE:

 detailed instructions on how to 

build the tail wheel bracket is shown on sheet 2 of the CAD drawings.

36) 

Cut a slot in the upper rear fuselage post to match the third rudder hinge 

location. Very carefully and accurately mark the location of the tail wheel 
wire where it will go into the rudder. Drill a hole for the wire into  the rudder 
using a 1/16” drill bit. Using a heavy gauge T-pin works great for 'pilot' 
drilling the hole. Be sure to drill straight into the rudder both vertically and 
horizontally. There is no need to under cut or inset the tail wheel wire into 
the rudder. Insert the three rudder hinges into the slots of the rudder. There is 
no easy way to accomplish the next step. You will just have to work 
methodically and carefully in order to get the three hinges 

and

 the tail wheel 

wire all lined up at the same time and install the rudder to the fin and 
fuselage. Once the rudder is installed the hinges can be secured with thin CA 
glue. Move the rudder full travel both ways before the glue sets to ensure full 
rudder travel with no binding.

37) 

The covering over the rudder servo opening can now be cut away.

38) 

The main landing gear is installed next. Simply puncture a hole in 

the film covering with a drill bit and insert the two main gear wires into 
the torque block holes. Secure the wires with the supplied steel straps 
and screws. Use a 1/16” drill bit for the screws. Solder a #6 flat washer 
on each main gear wire at the bend so that the wheels do not get 'stuck' at 
the bend in the wire. Secure the wheels with 5/32” wheel collars.

TIP: 

Drill the screws holes BEFORE the landing gear wires are in place. 

It will be MUCH easier!
