preparing Your transmitter
1. Program the throttle channel travel to 100% for both high and
low endpoints.
2. Select a linear throttle curve. You will program your normal throttle
curves later.
rpm Sensor Installation
Mount the RPM sensor and bracket to the backplate screws of your engine as shown.
• Threadlock must be used on the screws.
• The RPM sensor bracket is adjustable by extending or retracting the rpm
sensor and fastening the screw in place.
• Connect the RPM sensor to Aux 3.
throttle arm Setup
1. Disconnect the throttle linkage from the throttle arm.
2. Make sure the throttle curve in your transmitter is linear.
3. Move the throttle stick to 50% and make sure the throttle barrel is open 50%.
4. Adjust the throttle arm and the servo arm so they are parallel to each other.
5. Select holes in the servo horn and the throttle arm to achieve the full range
of throttle motion. The transmitter servo travel must stay above 100%.
6. Program your normal throttle curves for flying.
WarnInG: For first-time use or when making mechanical changes that involve throw, always ensure you reset the servo limits to prevent binding. Not
doing so will cause the helicopter to crash, resulting in property damage and injury.
