I’m retrofitting an Opterra 2m Flying Wing with an mRo Pixhawk 1 using the Buffalo FX-79 Airframe with v1.8.0Dev firmware.
- I first calibrated the ESC directly with the Rx to confirm MAX-MIN endpoints.
- Power cycled and it emits 1 beep, then 3 beeps for 3S, then the musical tones to confirm it’s ready for use.
- Motor responds to full range of throttle.
- Then used the ESC Calibration in QGC for good measure.
After power cycling the battery, the ESC will beep once, then 3 times to confirm 3S battery but will not go any further, as if it senses the throttle is not at minimum? I have a suspicion it has something to do with the ESC where it’s looking for some other lower PWM signal to allow it to continue its bootup sequence. I was hoping some might have an idea on how to resolve this.
