Motor Installation: 

 

Install the motor mount to the motor.  Mount the 

motor to the firewall using #2 servo mounting 

screws.  Connect the motor wires to the ESC.  You 

can use forceps through the air intake hole to connect 

the bullet connectors.  Check to see that the motor is 

turning in the correct direction.  If not, switch any 

two of the motor wires connecting the ESC.  The ESC 

can be mounted with double-sided tape or Velcro to 

the inside of the fuselage bottom.  

Tip:  Whenever you attach double-sided tape or 

Velcro to foam put a thin coat of 5-minute epoxy on the foam and let it thoroughly cure 

before attaching the tape or Velcro. 

 

Tip:  The smooth, flat side of the ESC is the heat sink.  Attach the Velcro or tape to the 

other side. 

 

Glue the hood scoop in place. 

 

Radio installation: 

 

Attach the receiver near the rear of the wing 

opening with Velcro or double-sided tape.  The 

ailerons can be wired with a 3" micro wire "Y" 

connector or if your receiver allows for direct 

connection of the ailerons to the receiver, use 

two 3" servo extensions.  The removable wing 

provides access to the battery so make sure 

you have enough slack in the aileron wires to allow the battery to be installed and 

removed. 

 

Setup: 

 

The CG is located 2 ⅝" from the leading edge of the wing.  The battery is 

mounted slightly forward of the CG so you can use just about any weight battery 

without affecting the CG too much.  Loosely locate the battery in the fuselage, install 

the wing and check the CG.  When you've determined the correct battery location, mark 

the location on the inside of the fuselage and install the battery with Velcro.  The 

battery can be moved slightly forward or back to fine tune the CG. 

 

A 2-cell Li-Po 1000 to 1300 mAh 20C battery is recommended for the average RC pilot.  

This will give you plenty of performance while keeping the speed down.  For those of 

you hot shot pilots, use a 3-cell 1000 to 1300 mAh 20C Li-Po and be ready!  This little 

guy screams!  

 

A 1000 mAh 15C battery is lighter and therefore a better choice for all out performance, 

but the heavier batteries have the added advantage of not pushing the Li-Po batteries 

to their limits.
