Before the first flights, or in the event of an accident, make sure the control
surfaces (Rudder, Elevator and Ailerons) are centered (aligned) with the rest of
the surface. If the control surfaces are not centered, centering can be achieved
by following the steps below:
• Pullthetubefromtheclevistothelinkage.
• Carefullyspreadtheclevis,theninserttheclevispin
into the correct hole in the control horn.
• Movethetubetoholdtheclevisonthecontrolhorn.
IMPORTANT: SAFE Technology is not active until you advance the throttle
past 25%. All trimming and control direction test should be done before SAFE
technology is activated.

Recommended Rates
Use low rates for decreased control throws in all flight modes
Use high rates for increased control throws in all flight modes
An aircraft with a correct CG has its weight balanced at a calculated point
where the entire airframe will balance when suspended at that point.
After installing the battery (in the recommended position) and before
powering on the ESC switch, verify the CG by supporting the aircraft 79.0mm
(approximately 3.125 inches) back from the front edge of the wing, as shown.
Tip: Balance the aircraft on your fingertips near the fuselage under the wings.
• 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.
When flying with correct CG in beginner mode, the aircraft should climb
gradually at full power and fly level at 50%–60% power with no elevator input.
If the aircraft CG is too far forward (nose heavy), up elevator is required to fly
level at 50%–60% power. If the aircraft CG is too far aft (tail heavy), down
elevator is required to fly level.
Adjust the battery position as needed.
