4. Installation of the Direct Powered Transponder
The transponder must be mounted
horizontally
at all times, preferably inside the RC
model car. The position of the transponder must be identical in all RC model cars
competing in the race.
Transponders may not be positioned more than
15 cm / 6” away
from the detection loop,
with no metal or carbon fiber in-between. It is preferable to mount the transponder as
close as possible to the detection loop. Make sure the transponder can not get detached
during a race.
To mount the direct powered transponder a nut and bolt can be used. Double-sided
sticky tape can be used, but this is not advised when liquid fuels are used in RC model
cars.
Locate the direct powered transponder in your RC model car in such way that it has a
free view at the detection loop. Keep the power wire neat and tidy in the RC model car so
it can not give you any trouble while driving the RC model car.
The power connector is a standard servo plug. This servo plug can be connected to a free
channel of the radio receiver. This channel can be a 3
rd
channel or battery channel. When
no free channel is available a Y-splitter servo wire can be used to connect the direct
powered transponder to your radio receiver. Your local hobby store can provide you with
a Y-splitter servo wire if necessary.
If the polarity of the servo plug does not match the polarity of the radio receiver, you can
change this (red wire is +). This is done by very carefully lifting the plastic lugs of the
servo plug with a hobby-knife (be careful not to cut yourself). When the plastic lugs are
lifted you can very carefully remove the connectors from the plug. Reinstall the
connectors into plug according to the polarity of the radio receiver you use. Push the
plastic lugs
very carefully
back into the servo plug and make sure the connectors are
fully seated into the plug.
Whenever power is applied to the radio receiver, the direct powered transponder will
show a green LED on both sides. These green LEDS indicate that the direct powered
transponder is working.
Make sure the transponder can not get detached during a race.
