All sizes of nitro powered helicopters
500-class and larger electric helicopters
Co mpatible with all Spektrum™ and JR® DSM2™ full range
transmitters including:
Spektrum DX6i (RevLimit function not available as only
six channels are present)
Spektrum DX7
JR X9303 2.4
JR12X
Note: Not compatible with Spektrum’s DX6 parkflyer system (DSM)
Spektrum’s AR7100 series receivers offer the ultimate system for
high-performance nitro or 500-class and larger electric helicopters.
Combining the bullet proof radio link of Spektrum’s DSM2
technology with a built-in regulator for the Rudder, Aux2, Gear and
Throttle channels and an integrated RevLimit limiter (AR7100R only),
the AR7100 series receivers make installation of these normally
complex devices clean and simple.
The AR7100 features a “Fail-On” soft switch to ensure reliability and
heavy 16AWG low resistance input power leads for uninterrupted
power even under the most demanding high-current draw
applications. The newly developed backplate rpm sensor makes
this integrated receiver, limiter and regulator system the easiest and
neatest possible to install with only one external rpm sensor lead for
the limiter. Designed and developed by helicopter experts, the all-in-
one integrated design of the AR7100 takes the hassle out of installing
and properly setting up separate receivers, regulators and limiters.
Applications
Introduction
Features
Spektrum’s AR7100 and AR7100R receivers feature 5.2-volt regulated
output power to the Rudder, Aux 2, Gear and Throttle channels
allowing high voltage to be used to power cyclic servos for increased
performance while the gyro and throttle servos are regulated to 5.2
volts, necessary to be compatible with most manufacturer’s gyros and
tail rotor servos. The “R” version (AR7100R) features an integrated
RevLimit™ limiter that includes an easy-to-install backplate rpm
sensor eliminating the hassles of installing magnets in the fan
and mounting hall-effect rpm sensors on the engine or frame. And
because it’s integrated with a single rpm sensor lead that plugs into
the receiver, the AR7100R greatly simplifies limiter hookup and
installation.
• Regulated 5.2-voltage output to the Rudder, Gear, Aux 2 and
Throttle channels allowing the cyclic servos to be powered at
high voltage for increased performance while the gyro and throttle
servos are powered by the necessary compatible lower voltage
(5.2V).
• AR7100R incorporates an integrated RevLimit limiter with
backplate rpm sensor offering the cleanest, easiest installation
available.
• Easy-to-mount backplate limiter rpm sensor eliminates the hassle
of mounting magnets, brackets and rpm sensors.
• Heavy-duty 16AWG input leads pre-wired with EC3 connector.
• Dual outputs on the Throttle and Aux 2 channels (regulated to 5.2
volts/ unregulated).
• One internal receiver and up to two remote receivers.
• Soft switch fails-on if the switch is damaged.
• Optional charge ON/OFF adaptor lead (included) allows charging,
battery monitoring and ON/OFF through one easily accessible lead.
• Two types of failsafe—SmartSafe (throttle only) and conventional
failsafe (all servos).
• Quick Connect - If a power interruption (brown out) occurs the
system reconnects in less than .25 seconds.
• Flight Log compatible.
• Compatible with all Spektrum and JR DSM2 full range
radio systems.
Note: The AR7100/AR7100R uses a specifically designed switch.
Conventionally wired switches are not compatible with the AR7100.
