Control throws

Please, follow carefully the recommended linkage setups for ailerons and elevators. 

 For the AILERON we recommend the following throws: 

Low rate: 20° up / 20° down Expo: 40% 

High rate: 40° up / 40° down Expo: 80% 

 For the ELEVATOR we recommend the following throws: 

Low rate: 20° up / 20° down Expo: 20% 

High rate: 45° up / 45° down Expo: 50% 

 For the RUDDER we recommend the following throws: 

Low rate: 30° left / 30° right Expo: 30% 

High rate: 45° left / 45° right Expo: 60% 

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. 6% 

* if you have a programmable computer radio. 

Rates and expos

Use the recommended expos to soften the feel of the model, expecially on high rates. The goal is to 

get the model to feel the same around neutral as it does on low rates. 

Use low rate settings for all flying, included starts and landings, and high rate for snap, spins etc. 

Recommended CG

 

The recommended Center of Gravity location is 145mm behind the leading edge of the wing 

against the fuselage. 

Use the Flight Power battery pack, moving it forward or backward, to achieve the correct balance. 

Range test your radio

• Before fly, be sure to range check your radio as manufacturer’s instruction manual of you 

radio-system recommand. 

• Double-check all controls (aileron,elevator, rudder and throttle) move in the correct 

direction. 

• Be sure that your Flight Power batteries are fully charged, as per the instructions and that 

your radio is fully charged as per its instructions.
