| Are you talking about the knobs? It is somewhat documented what they do but it is a bit confusing. I think I figured it out last night: Normally Dip switch 10, 11 and 12 are off. You should usually keep them all off by default. Only turn one on at a time.
Dip switch 10 controls the left knob for MIDRANGE pitch adjustment. If you flip it ON it will allow the left knob to vary the pitch like a trim knob. flip the switch, get the pitch trimmed the way you want it using the left knob, then flip the dip switch back OFF to lock it. I think this adjustment should be done NOT flying and just using a pitch gauge.
Dip switch 11 controls the mid range throttle trim. This adjusts the center area of the V curve for the 3D/Idle up. Flip 11 on. Adjust the right knob to vary the midrange throttle. Do this while hovering or on a test stand. When done flip Dip switch 11 back to off.
Dip Switch 12 controls gyro and tail mixing. With it turned on, left knob adjusts the collective to tail mixing. right knob adjusts gyro gain. Not sure whey you need tail mixing if you have a HH gyro though. Read Section C in the manual 7.4 will explain this. |
