Calibration
IMPORTANT: When calibrating the system, the limiter percentages must be
adjusted to 100% normal and -100% in ST1.
During calibration the RevLimit stores the output limits of the Gear channel. It’s
necessary to adjust the Gear channel output to 100% in both directions during
calibration.
1. Adjust the throttle operation so that the servo travel is near 100% in both direc-
tions at full throttle and at full idle. This may require lengthening or shortening
the servo horn.
2. Make sure that the Gear channel is traveling 100% in both directions when the
switch that controls the limiter is flipped (flight mode on the X9303 2.4GHz or
Aux 2 on the DX7). The servo monitor is helpful here.
3. Set the throttle trim to the low (off) position.
4. With the throttle stick at low throttle, turn on the transmitter then turn on the
receiver; within three seconds toggle the switch that will control the limiter. The
ACT LED on the receiver will flash green indicating that the calibration mode is
successfully entered.
5. Raise and lower the throttle stick throughout its full range. The throttle endpoint
will be stored.
6. Exit the calibration mode by toggling the controlling switch twice. The ACT LED
will stop flashing, indicating a successful calibration was achieved.
7. To verify correct calibration, lower the throttle stick below the 25% position and
the ACT LED should turn off. Above 25% the ACT LED (green) should be on.
Note: Calibration only needs to be performed when first setting up the RevLimit, or
when changing throttle servo throws, or if the unit is installed in another helicopter.
To Verify the RPM Sensor is Functioning
With the system calibrated and turned on, rotate the engine over by hand and note
the SENS LED on the receiver. When the crankpin passes the rpm sensor, the SENS
LED will light red indicating the rpm sensor is working properly.
