HITEC Ranger III FM - Manual (Page 7)

INSTALLATION
When installing the radio system to the model, please follow the detailed instructions for the
model kit.
A.Normal Installation (non BEC)
If you are using the regular mechanical speed control that usually comes with the model
kit, you will need both servos, and the battery harness that comes with the radio set.
Incidentally this is the installation method for the engine equipped model as well.
B.ESC installation (Electronic Speed Control)
You may wish to use an ESC in place of the mechanical speed control and throttle servo.
This will allow more precise control as well as less power consumption. Please note that
most ESC’s are already equipped with BEC so you can simply plug into channel two of
the receiver.

HELPFUL HINT
A.BATTERY
Always take extra care that all the batteries in the radio set are fully charged (NiCad) or
fresh (Dry) when operating you radio. Otherwise the receiver range will substantially be
reduced and lose control thereby damaging your model and or people. When you re-
charge your transmitter NiCads with a charger jack, be careful of its polarity. The inner
contact should be positive (+), the outer negative (-). For your convenience, we recom-
mend our genuine overnight charger. CG-22(220V0 or CG-25(110V).
B.ANTENNA
Both the transmitter and the receiver antenna must be fully extended when in use. Be
careful that you do not cut off the excess receiver antenna wire or bundle it. This will
severely cut down on the operating range.
C.XTAL CHANGE
When changing the frequency to another channel, make sure that you match the trans-
mitter to the receiver channel. Also you must make sure that they are replaced with only
genuine Hitec single conversion FM xtals as not all xtal makes are compatible with each
other. Also remember that you can change frequencies only within the same frequency
band, which means you cannot change to 72MHz from 75MHz. (Also in the US, you
may not be allowed to change the transmitter xtal).
