* The receiver power supply does not seem to be sufficient. The voltage during operation dropped in a critical area (<3.5 Volts). Use a stable power supply and make sure that the wiring and plugs are dimensioned big enough and feature low contact resistance. On large helicopters we recommend to use the MICROBEAST PLUS HD or AR7300BX unit with high power input.

===The helicopter drifts slowly around its vertical axis. The rudder servo creeps to maximum deflection slowly.===

When using Heading Lock mode the system compares the rotation rate of the helicopter with the commanded rotation rate from the stick input all the time. So basically this can have two reasons:<br />
 +
<br />
 +
1) Gyro is measuring a rotation even if there is none. This can happen from hard vibrations disturbing the sensor measurement or also by gyro drift due to high temperature change or a defective sensor. As with other electrical devices make sure to give the system time to acclimatize before powering it up, especially when flying on a cold winter day or during a hot summer.<br />

2) Stick is commanding a rotation even when it seems to be in center position. Check all your trimmings on the transmitter. They must be 0 in all flight modes. Make sure to keep the sticks centered during power up as the system learns stick center positions each time it performs the init sequence. This is necessary because most often stick potentiometer positions vary slightly, i.e. due to different ambient temperature. This issue can solved by using stick deadband but to keep deadband as low as possible and to increase overall performance MICROBEAST / MICROBEAST PLUS learns stick position directly before flying. However, if you see your sticks do not center properly, i.e. when pushing and releasing the stick softly the servo starts to creep into one direction and only will stop when tapping the stick into the opposite direction, then you can increase the Stick Deadband at Parameter menu point E.<br />

===When moving the rudder stick in Heading Lock mode the servo does not go back to center positions but stays somewhere.===

This is normal behavior when using the gyro in Heading Lock mode!<br />
