| Problem description | Solution |
| Swashplate or tail drifts after initialization | Check trims and subtrims. Sticks in neutral position must be 0%, see the Diagnostics tab. Increase Stick deadband in Advanced tab. |
| Rudder or cyclic is not precise | Increase cyclic gain and/or increase the gyro gain in the transmitter. Add exponential in the transmitter. |
| Aggressive cyclic pitch movement or fast forward flight leads to rapid, large tail oscillations | Decrease pirouette consistency in the Advanced tab gradually by 10 until this disappears. Check the tail mechanics for binding. |
| Model oscillates in elevator or aileron axes | Decrease cyclic gain in Sensor tab. |
| Tail oscillates rapidly | Decrease gyro gain in the transmitter. |
| Model pirouette rotation is too slow/fast | Increase/decrease rotation speed for rudder in Sensor tab. |
| Servos jitter randomly without external influences | Check the cable connection between the receiver and the unit. |
| During stationary pirouettes model drifts | Check the Subtrim configuration in the Servos tab. It seems to be inprecise. |
| Aggressive elevator stick movement leads to bouncing | Increase elevator filter in Advanced tab and/or decrease cyclic feed forward in Advanced tab. |
| Cyclic feel is delayed or disconnected | Increase cyclic feed forward in Advanced tab. |
| Elevator servo is not moving when initialization is finished | Flight log from the previous flight was saved. View the log in the Diagnostic tab and fix reported problem. |
| Swashplate is jumping in a cycle when initialization is finished | The unit was started with the Rescue mode engaged. Turn off the rescue from your transmitter. |
| Rudder stop is not equal for both sides | Check rudder servo center position, rudder mechanics. You can also try to lower rudder limit for the side where bounce-back occur. |
