j) Switching on the Speed Controller
Switch on the speed controller.
Depending on the speed controller you use, you may now have to programme the neutral and full throttle positions
for forwards and reverse driving.
For this, observe the operating instructions of your speed controller.
If the vehicle drive starts although the throttle/brake on the transmitter is in the neutral position, then adjust the trim
on the transmitter until the motor stops.
Now check the drive and steering functions of the vehicle.
k) Adjusting the Steering
After completing the vehicle as described in the above sections, you have to adjust the steering last to control the
vehicle properly.
For a gun-handle transmitter, release the wheel to let it take its centre position (neutral position). Put the steering
function trimming in its centre position as well.
If the transmitter has a dual rate function, deactivate it.
The servo lever at the servo now needs to point vertically upwards. If this is not the case, you may correct slight
misadjustments with the trim of the steering function on the transmitter.
If the trimming path is not sufficient, the servo lever must be repositioned accordingly.
Put the steering servo in the middle position (neutral position). Then switch off the speed controller and disconnect
the drive battery from the speed controller. Remove the steering servo and turn the screw that holds the servo lever
at the steering servo out.
Pull the servo lever off of the servo and push it on so it is at a right angle to the servo (servo must be in the middle/
neutral position; after installation of the steering servo, the servo lever must point up vertically.).
Fasten the servo lever to the servo again and install the steering servo. Only now connect the drive battery to the
speed controller and switch on the speed controller. Now check the steering function again.
Check the steering deflection to the left and right. The servo must not run to the block. This means that the steering
mechanics cannot move any further but the servo tries to implement the control commands. This will not only overload
the servo drive, the servo also consumes a lot of power and reduces the driving time.
Depending on which remote control system you use, the servo path at the transmitter can be limited (e.g. designated
as „EPA“ („End Point Adjustment“). A dual rate setting can also be used for this.
The precise straight-running settings are made later, when driving the vehicle, by trimming the steering function.
l) Attaching and Fastening the Car Body
Push the aerial tube from the bottom of the body through the respective opening.
Put the car body onto the car body holders and secure them with suitable car body clips.
