CG (Center of Gravity)
The center of gravity position as shown
An aircraft with the correct CG has its weight balanced on the center of the aircraft for safe and stable flight.
The aircraft CG and weight are based on having the recommended battery installed.
(7.4V 2S 650mAh 20C Li-Po Battery, 35g)
The CG location is on the carbon tube under the bottom of the wing. Balance the aircraft on your fingertips at
the carbon tube and adjust the battery position as needed to get the aircraft to balance correctly.
- If the nose goes down, move the flight battery back until the aircraft balances.
- If the nose goes up, move the flight battery forward until the aircraft balances.
Pre-Flight Checklist
Always turn the transmitter (required to complete) on first
Make sure the transmitter controls are neutral, the throttle is at the lowest position and set the THROTTLE
CUT switch on the transmitter to the RED DOT position
Plug the flight battery into the aircraft and place it on a level and in an unobstructed open field
Check the aileron movement
Push the aileron stick left, left wing will tilt up and right wing will tilt down
Push the sileron stick right, left wing will tilt down and right wing will up
Check the elevator movement
Push the elevator stick up, the back edge of left and right horizontal tail will tilt down
Push the elevator stick down, the back edge of left and right horizontal tail will tilt up
Check the rudder movement
Push the rudder stick left to point the nose of aircraft left
Push the rudder stick right to point the nose of aircraft right
Check the Alignment
Keep the throttle at zero and aileron, rudder, elevator to neutral. All the wing, horizontal tail and vertical fin
should align to the aircraft. Adjust the pushrod of the servo if one of them do not align to the aircraft. Refer
to the “Control Surface Centering” for more information
If the aircraft control surfaces do not respond as above, DO NOT FLY
