Warning

Before starting assembly
Before starting the assembly, remove each part from its bag and protection for a prior
inspection. Closely inspect the fuselage, wing panels, rudder, and stabilizer for
damage. If you find any damage or missing parts, contact the place of purchase.
If you find any wrinkles in the covering, use a heat gun or covering iron to remove
them. Use caution while working around areas where the covering material overlap to
prevent separating the covers.

Control throws
Please, follow the recommended linkage setups:
For the AILERONS we recommend the following throws:
High rate: 40° left & right
Normal flight: D/R: 30% Expo: 20%
Snap: D/R: 100% Expo: 80%
Spin & 3D: D/R: 100% Expo: 80%

For the ELEVATOR we recommend the following throws:
High rate: 40° up & down
Normal flight: D/R: 30% Expo: 30%
Snap: D/R: 40% Expo: 40%
Spin & 3D: D/R: 100% Expo: 90%
For the RUDDER we recommend the following throws:
High rate: 40° left & right
Normal flight: D/R: 40% Expo: 60%
Snap: D/R: 50% Expo: 70%
Spin & 3D: D/R: 100% Expo: 90%
Note: the Expo is (+) for JR systems, and (–) for Futaba systems.
Mixing
For best performance, we recommend a linear-mix*:
Rudder → Elevator UP
When you give full rudder to the right or left side, the elevator have to go up (positive)
approx. 1-2%
* if you have a programmable computer radio.
Recommended Center of Gravity
The recommended CG is 130mmbehind the leading edge of the TOP wing
against the fuselage.
40mm is good for no wind condition
You can use the battery pack, moving it forward or backward, to achieve the correct
balance.

Pre-flight
Never attempt to make full throttle dives!
If the airframe goes too fast, such as in a high throttle dive, it may fail.
Throttle management is absolutely necessary.
Range test your radio
Before fly, be sure to range check your radio as manufacturer’s instruction
manual of you radio-system recommend.
Double-check all controls (aileron, elevator, rudder and throttle) move in the
correct direction.
Be sure that your motor battery pack is fully charged, as per the instructions
included with your batteries and that your radio is fully charged as per its
instructions.
Finally...have nice flights!
