3. Q: I’ve heard that the DSM system is less tolerant of low voltage. Is that correct?
A: All DSM receivers have an operational voltage range of 3.5 to 9.6 volts. With most
systems this is not a problem as most servos cease to operate at around 3.8 volts. When
using multiple high-current draw servos with a single or inadequate battery/ power source,
heavy momentary loads can cause the voltage to dip below this 3.5-volt threshold thus
causing the entire system (servos and receiver) to brown out.
4. Q: Sometimes my receiver loses its bind and won’t connect, requiring rebinding. What
happens if the bind is lost in flight?
A: The receiver will never lose its bind unless it’s instructed to. It’s important to understand
that during the binding process the receiver not only learns the GUID (code) of the
transmitter, but the transmitter learns and stores the type of receiver that it’s bound to.
If the transmitter is placed into bind mode, the transmitter looks for the binding protocol
signal from a receiver. If no signal is present, the transmitter no longer has the correct
information to connect to a specific receiver and in essence the transmitter has been
“unbound” from the receiver.
For safe and reliable performance of your RC model, please carefully read and follow these
guidelines:
1. Radio control models are not toys. They are capable of inflicting serious injury to
people and property. Use caution at all times when operating your model.
2. You are responsible for the safe operation of your RC model. You must properly install,
test and operate your model with a clear sense of that responsibility. Do not take risks
that might endanger yourself or others.
3. Running an RC car in the streets is very dangerous to both drivers and models. Avoid
running your model in areas occupied by full-size automobiles. To locate areas where
you can safely operate your model, you should contact your local hobby shop for RC
tracks or clubs in your area.
4. If at any time while operating your RC model you sense abnormal model functioning,
end your operation immediately. Do not operate your model again until you are certain
the problem has been corrected.
CAUTION: Control of your model is impossible without sufficient voltage for the
transmitter and receiver. A weak transmitter battery will decrease your range of
operation and a weak receiver battery will slow servo movement and decrease
your range of operation. Check your receiver pack voltage often to avoid losing control
of your model.

Steering tension is adjustable via the recessed screw located beneath the steering wheel (see
page 11 for exact location). Turning the screw clockwise increases the steering tension.

as molded into the battery holder. If the transmitter voltage fails to register, check for correct
battery installation and review the voltage again.
