Dual Rates
Your 120 SR RTF model comes with the Blade MLP4DSM transmitter. This transmitter’s dual rate feature lets the
pilot change between high and low control rates for the aileron, elevator, rudder and throttle channels.
When powered on, this transmitter is automatically in high-rate mode. •
Change rate modes by pushing the right-hand control stick down into the case until it clicks while the •
transmitter is powered on.
High-rate mode is shown by the transmitter’s LED glowing solid red. In high-rate mode the controls can reach •
their maximum values. This mode is typically preferred by experienced pilots for maximum control authority.
Low-rate mode is shown by the transmitter’s LED blinking continuously. In low-rate mode the controls are •
reduced to a percentage of their maximum values. This mode is typically preferred by (and best for) first-time,
low-time and other pilots interested in smoother and more easily controlled hovering and flying.
Choosing a Flying Area
Consult local laws and ordinances before choosing a
location to fly your aircraft.
When ready for your first flight, select a relatively open indoor
area free of people and obstructions. While it is possible for
experienced pilots to fly the 120 SR in relatively small indoor
areas with great success, we strongly recommend an area
with at least 10-feet by 10-feet of floor space and no less than
8-foot ceilings when making your first few flights.
Once you properly trim your helicopter and become familiar
with its handling and capabilities, you will be able to fly in
other smaller, less open areas.

Lift the model off the ground just a few inches and concentrate on balancing the throttle stick position so •
that the model holds a steady hover altitude. In some cases you may need to make a few short “hops” to
an altitude of just a few inches until familiar with the control inputs and trim settings required to maintain a
steady hover and altitude.
The 120 SR requires minor throttle adjustments to maintain its altitude in hover. Remember to keep these
throttle adjustments as minimal as possible as large adjustments could result in a loss of control and/or a
possible crash.
