Throttle curves<\/h4>\n\n\n\n For OMP Protocol, there are no throttle curves on the Radio Transmitter as throttle curve is fixed inside the Helicopter. For other protocols, the below curves are used.<\/p>\n\n\n\nCurve<\/th> Curve name<\/th> Function<\/th><\/tr><\/thead> CV2<\/td> TCn<\/td> Throttle curve for Normal mode<\/td><\/tr> CV3<\/td> TC1<\/td> Throttle curve for Idle-up 1<\/td><\/tr> CV4<\/td> TC2<\/td> Throttle curve for Idle-up 2<\/td><\/tr><\/tbody><\/table>Throttle curves<\/figcaption><\/figure>\n\n\n\nPitch curves<\/h4>\n\n\n\n For OMP Protocol, there are no pitch curves on the Radio Transmitter as pitch curves are fixed inside the Helicopter.

The dead band curve is mixed with Aileron and Elevator controls to get rid of the dead band. Curve CV12 (DBD) is used as dead band curve.<\/p>\n\n\n\n
