Read this manual carefully to achieve the best results with your Alpha 150Q GPS and first of all to safely control your models. If you experience any trouble during operation, take the instructions to help or ask your dealer or Graupner Service Centre.
Target group A quadcopter of the series Alpha 150Q GPS is not a toy. This copter is not suitable for children under 14. For questions about radio-con- trolled models, please contact an experienced RC model expert or a RC model club.
Pro HoTT are pre-assigned with pattern settings for dif- ferent Graupner copters. For the operation of the Race copter Alpha 150Q GPS it is provided the model memory 10 named with "Alpha GPS". This model memory can also be found in the download area of the copter product page.
Do not expose it to vibrations or to extreme heath or cold. The models may only be operated remotely in normal outside temperatures such as from -10°C to +55°C. • Always use all your Graupner HoTT components only with the latest firmware version. 8 / 48...
• If you have questions which cannot be answered by the oper- ating manual, please contact us (contact information see page 5) or another expert in the field. WARNING • During programming, make sure that connected electric motors do not start unintentionally. Injury risk by the turning propel- lers! For safety reasons always remove the propellers when programming.
Notes • Remove the battery from the model when transporting or when not in use. • During transport protect the model and the transmitter from damages. Charge the LiPo battery Connect the LiPo battery to the supplied charger and charge it as described in the corresponding manual.
VersaCopt different Graupner copters. For the operation of the Race copter Alpha 150 Alpha 170 Alpha 150Q GPS it is provided the model memory 10 named with Alpha 1703D Alpha GPS ––– "Alpha GPS". If required, this model memory can also be found in the download area of the copter product page at www.graupner.de.
Attention As mentioned above, the receiver of a Race copter Alpha 150Q GPS is in binding mode approximately 15 seconds after the battery is plugged in. If the copter is already bound to a specific transmitter...

Flight control Control mode According to the transmitter instructions, the appropriate control mode and, if necessary, "motor front / rear" must be set. Usually "backwards" so that the channel 1 indicator in the servo display indi- cates -100% in the "motor off" position of the "throttle / pitch control stick".
Installing the propellers CAUTION Risk of injury by rotating propellers in case the motors start. Always unplug the connector to the battery before working on the propellers. Install the propellers as shown in the picture on the left. Be sure to attach the right propeller to each motor.

POWER 2SENS. This parameter allows you to set a kind of gyro suppression. Higher values result in an increased suppression towards full throttle. R/N DYNAMIC Higher dynamic values provide a more direct feel for the flight (3D flight 50 ... 100), lower dynamic values for smoother flight record- ings, rounder freestyle flying and races (30 ...
YAW Display The general comments on PID control in the description of the roll / pitch display are also applicable here. YAW P The P factor is responsible for the snap to yaw. Higher values result MULTICOPTER YAW YAW P in a faster stop.

ALTITUDE HOLD I This parameter determines the behaviour of the copter in the case of deviations from the nominal height due to external influences as a function of the size of the deviation. This value must be set so that deviations are compensated as well as possible without the copter oscillating around the desired height.
POS HOLD II This parameter compensates for the time-integrated distance differ- ence. This value must be set so that the desired position is kept as good as possible. This parameter does not usually have to be adjusted and is currently ineffective.

CONTROLLER SETTING To initialize the controller, the signal of the motor / pitch control stick of the transmitter is transmitted directly to the speed controller of the copter. Setting the speed controllers step-by-step 1. Remove rotors for safety reasons 2. Make sure that the transmitter-side pitch signal reaches ± 100%. 3.

Adjustment range: MIN (deactivated), 1 …100, (0)Ch5, (50)Ch6 … (50)Ch16 Alternatively, the effect on the I value can also be adjusted by the transmitter. To do this, a rotary or slider control is assigned to one of the control channels 5 ... 16 and the remaining settings are left at the default values.

COMPASS CALIBR. After each change of the airfield the compass has to be recalibrated. In contrast, the current calibration described below does not have to be repeated every time. Notes • When using an HD camera, it must be turned on when calibrat- ing the compass.
Page 40
• The current calibration becomes more accurate when the nose of the copter points either the west or east direction, because then slight deviations can better detected. • Furthermore, the suspension position must first be determined and remembered before, if necessary, the propellers are reversed and mounted vice versa, so that the copter is pressed to the ground instead of lifting.
LOGGING Logging 0 displays the Euler angles in the Copter telemetry display and also allows the position display using the Graupner HoTT OSD No. 33641 on the FPV screen or in the FPV video goggles. The default value “10” indicates the compass direction in degrees in 11.6V...
