Glue the plywood plate to the bottom of the fuselage 
with the slot aligned with the slot in the bottom piece. I 
add hot glue around the edges of the plywood to better 
secure it.
Insert the landing gear wire into the slot and secure it 
with the plastic straps and 4 of the screws that came 
with your servos. Install the wheels and the wheels 
collars.

Center of Gravity: 

The battery can be moved on the tray to adjust the CG 
to the recommended 2” behind the leading edge of the 
wing. 

Radio setup for wing: 

Computer radio with correct receiver for a 4 servo 
wing can be used or 5 ch receiver with Y-harness for 
ailerons and reversing Y-harness for flaps. See your 
radio's instructions for specific information.

For a computer radio, each of the wing servos will plug 
into a separate channel on the receiver. 2 outer servos 
assigned to aileron and the 2 inner servos assigned to 
flaps. For improved roll rate the ailerons can be mixed 
to the flaps so the flaps move with the ailerons. We do 
not advise setting up the ailerons to function as flaps as 
this will increase the chance of wing stall.

For a 5 ch radio setup, both aileron servos will plug 
into a standard Y-harness and then into the aileron 
channel. The aileron servo arm should be angled 
forward about 30 degrees. This will provide 
mechanical aileron differential which will correct any 
adverse yaw and help the plane roll with out yawing.
The flap servos plug into a reversing Y-harness so they 
will move the same direction and then into the flap 
channel.

Flight set-up:

Use your computer radio to set the final sub-trims, 
exponential and dual rates. Double check the control 
directions before your first flight. 

  

We have found that a 1300 mah 3s battery is perfect for 
giving good flight times and plenty of power as well as 
a proper CG.

The suggested control throws are +/- 30 degrees for 
high rates and +/- 20 degrees for low rates. 
Flaps can be set for anywhere from 10 deg to 45 deg.

Setting up Aileron differential where the ailerons will 
move about 40% more up than down will correct any 
adverse yaw and help the plane roll with out yawing.

We hope you enjoy your airplane.
Thank You,
