k) Switching on the Speed Controller
Afteryouhaveswitchedonthetransmitterandpreparedit(seechapter8.j),youcanswitchonthespeedcontroller.
Depending on the speed controller used by you, the neutral position and full throttle positions for forward and reverse
driving,aswellasfurtherfunctions,ifavailable,mayneedtobeprogrammedatrstcommissioning(e.g.therecharge-
able battery type, the undervoltage recognition, etc.). Observe the operating instructions for the speed controller used
by you.
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.
l) 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sufcient,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deection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.
