Connecting the speed controller
The battery connectors are equipped with a Japan connecting system. Thus, please use Graupner batteries
with the same connecting system.
The speed controller needs to be connected to the motor with 4mm plugs, order no. 2977 or order no. 94310.
Installing into the model
- Attach the motor to the motor mount using the screws provided. Adjust the effective screw length (place
washers under the head) so that the threads do not protrude protruding inside the motor casing. The winding
of your motor can be damaged, if the screws protrude inside the motor case. See motor instructions.
- Mount the speed controller in the model so that it is isolated from vibration and shock and make sure the
heatsink is free for best cooling. Make sure that there is sufficient cooling of the motor and speed controller
by directing adequate cooling air from the outside airflow.
Setting the Standard Mode / First operation
1. Make sure all the cable leads are properly connected.
2. Turn the transmitter on and check the servo travel of the throttle channel which should be ±100% or, with
Multiplex R/C systems, ±80%. Graupner/JR, Multiplex systems need reversing (REVERSE) the throttle arm
travel! With Robbe/Futaba systems, the latter should be set to “NORMAL” = 1.5ms. The throttle trigger should
now be either at position “Motor off”! The throttle range and neutral position is fixed. You may correct the
transmitter way and neutral position on the transmitter.
3. Turn the transmitter on (position “ON”), then push the throttle lever into position “Motor off ”.
4. Connect the battery to the controller, mind the correct polarity. Plug in the power battery and try only once
to plug in. Do not touch the contact several times.
5. Switch on the speed-controller.
6. The speed controller is now ready to use
7. Move the transmitter stick forward, to drive forward. Move it backward to drive backwards.
8. After operating, switch off the speed-controller and disconnect the drive battery.
Warning: Once the main power pack is connected, handle the model with extreme care – Ensure that
everyone is well clear of the propeller at all times. Rotating propellers are extremely dangerous!
Connect the main power pack just before the use and disconnect it immediately after using the model.
Attention!
If you do not want to use the BEC supply from the controller and
instead use a separate battery, you have to remove and isolate
the red wire (+) of the BEC plug as shown in the sketch. This
will prevent a backflow into the controller, which could destroy
the controller. If you want to connect a battery to the BEC system,
a diode (e.g. Schottky diode 91505) needs to be soldered
into the BECs red wire, so that the current can only flow from
the BEC to the receiver.
