5.3.7 Offset

^{Optional separate trims in addition to those for the normal condition. This function is used to automatically change the trim of a helicopter, for example, when transitioned from hover to flying at high speed. A clockwise-rotation rotor helicopter tends to drift to the right at high speed, so an aileron offset may be applied to offset the helicopter to the left.}

^{The necessary elevator offset varies with model geometry, so it must be determined by noting collective pitch changes at high speed. The rudder offset is affected by both revo. mixing and trim lever movement while in the offset function.}

^{ADJUSTABILITY:}

^{• Complete switch assign ability, plus a CONDITION option that creates/ switches between individual trims for each of the idle-ups.}

^{• When OFFSET is active (its switch is on), moving the TRIM LEVERS adjust the stored offset, not the trims in the normal condition.}

^{•When OFFSET is inactive (its switch is off), the OFFSET and any trim adjustments to it have no effect (model obeys the trim settings of the currently-active flight condition.)}

^{• When OFFSET is inhibited, trim adjustments made in any flight condition affect all flight conditions.}

^{• Rapid jumps caused by large offsets can be slowed using the DELAY function.}

^{• During OFFSET operation, the aileron, elevator, and rudder travels are displayed on each trim display in the Startup screen.}

^{Note: Remember, offsets and revo mixes are not recommended when using heading-hold/AVCS gyros because they conflict with the automatic corrections to trim and torque that AVCS provides.}
