Mount rudder servo linkages 

Using a similar technique to the elevator, mount the rudder control rod and horn.   
 
On the Super Honey Hawk there are only 2 control rod guides for the rudder as compared to the Phat 
Hawk.  Also, the Super Honey Hawk rudder pushrod is a 1.5 mm diameter rod to avoid flex across the 
tail rotor gap. 
 
The rudder pushrod runs on the outside of the tail rotor 'cage' (support carbon rods).  

Mount the nose motor 

Glue the supplied motor mount to the fuselage being sure to NOT get glue in the center hole, just the 
arms.  The center hole should remain clear of any debris to allow the rear axle of the motor to spin 
freely. 
 

Note: This is one place where hot glue (on a low setting) can be used to ensure a good, solid, bond that 
can also be removed easily with denatured (rubbing) alcohol if required later for motor fixes/changes. 

 
Once the motor mount has been installed, screw the motor to the mount.  Ensure that the wires come 
off the bottom left or right side of the motor/plane. 
 

Mount electronics 

Now that the heavy parts are on the plane, plug in both ESCs and Receiver (Rx) into their motors and 
servos. 
Temporarily tape the ESCs and Rx into your desired positions on the plane. 
Test the CG 

– which should be ~ 20 mm (3/4") in front of the wing spar. 

Move the ESCs and Receivers around to (as much as possible) get the CG as close to the right spot as 
possible. 
 

Note:  The Super Honey Hawk will likely require one battery to be right on the nose to balance 
out.  So at this stage you may need to temporarily stick it to the side of the nose to get things 
balanced.  Once you've installed the electronics you can come back and cut a slot in the fuse to 
centre the mass of the battery as close to the plane's core as possible. 

 
Once you have a good balance and placement Install the ESC and Rx onto the fuse.   
 

NOTE:  What works well is to cut thin slots in the bottom fuse right at the underside of the horizontal 
fuse/wing and 'jam' the ESC/Rx in.  Doing this right can even allow you to skip using any glue and save 
weight.

 

 
You can optionally install the main flight battery in the fuse now, but it might be preferable to do a test 
flight with the battery temporarily velcroed to the side to see where your preferred balance point is.  
Then later, cut a slot in for the battery. 

Glue on the Side Force Generators 

Using Foam-Tac glue on the SFG's.
