Press four 6-32 blind nuts into the holes as shown and apply 
some glue around each nut to prevent them from coming loose.

❏ 

4. Glue the two rear pieces together. Assemble the rest 

of the mount being sure to 

thoroughly

 glue all the joints 

together. We suggest using thin CA on all the outside joints 
and then running a bead of medium or thick CA along all the 
inside joints.

❏ 

5. A short length of 1/8" [3.2mm] wood dowel is included. 

Cut four 1/2" [13mm] pieces from the dowel. Drill 1/8" [3.2mm] 
holes approximately 3/8" [9.5mm] deep into the center of each 
forward tab. Glue a piece of dowel into each hole and sand 
them fl ush with the sides of the motor mount.

❏ 

6. Attach the brushless motor mount to the fi rewall using 

four 6-32 x 3/4" [19mm] machine screws, four #6 fl at washers, 
four #6 lock washers, and thread locking compound.

❏ 

7. Install the aluminum ‘X’ mount and prop adapter onto 

your brushless motor using the screws included with the 

motor and thread locking compound. Attach the motor onto 
the front of the brushless motor mount using four 6-32 x 5/8" 
[15.9mm] machine screws, four #6 fl at washers, four #6 lock 
washers, and thread locking compound.

❏ 

8. Locate the six plywood pieces that make up the ESC 

tray. Glue them together as shown.

❏ 

9. It is recommended to make a 3" [76mm] battery lead 

extension to make connecting your pack easier. In order to
