into place and install the LiPo battery to complete the assembly stage.
The motor pylon
The motor pylon is a high-quality item which is supplied in the set ready to use. The
associated speed controller is set up as standard to suit the DISCUS 2CT; this
eliminates the need for any programming. Please note that the operating instructions
for the PICO 8 speed controller are supplied separately in the pack.
Binding the GR-12 receiver in the model to your HoTT transmitter
The “BINDING” procedure varies according to the HoTT COMPUTER SYSTEM you
are using; please observe the following notes, and the section entitled “Binding the
receiver” in the manual supplied with your radio control system.
1. Give the LiPo flight battery and the transmitter battery a full charge.
2. Locate the right-hand stick on your transmitter, and move it back towards you to
the “motor stop” position.
3. Now connect the BEC plug and socket between the speed controller and the LiPo
battery.
4. Initiate the “BINDING” procedure, and then carry out a full check of the working
systems. The servo leads should be connected to the receiver in the following
sequence: socket 1: speed controller; socket 2: rudder servo; socket 3: elevator
servo. This means that the throttle (motor control) and direction (rudder control)
are both assigned to the right-hand stick on the transmitter, and the elevator to
the left-hand stick. Pulling the elevator stick back towards you causes the elevator
to deflect up; moving it away from you causes it to deflect down.
5. If necessary, use your transmitter’s “Servo settings” menu to correct the direction
of rotation of the servos, and set the control surfaces exactly to centre (neutral
position). This is very important, otherwise the model will not fly straight, and will
constantly tend to climb or dive.
6. Now it is time to check the motor function by cautiously moving the right-hand
stick forward (away from you). It is always better to test the motor outdoors, and it
is very useful to have a friend to hold the model securely while you operate the
transmitter.
