Spektrum AR7100R DSM2 7-Ch Heli Receiver w/RevLimit

Spektrum 7-Channel receiver for high-performance helis

Main receiver is 1-7/8” x 1-5/8” x 3/8”, weighs 32.5 grams. The AR7100R is Spektrum’s first purpose-built receiver designed specifically for demanding heli applications. The combination of a primary internal receiver and secondary remote receiver allows the AR7100R to be installed in the best possible configuration for high-performance helis, while exposing the receiver to the greatest possible RF signal at all times. Additionally, the AR7100R features Spektrum’s integrated RevLimit™ rpm limiter, which provides the consistent rotor speed needed for outstanding 3D performance. Complete with two user-selectable failsafe modes, a built-in 5.2V 2A voltage regulator and EC3 connectors, the AR7100R is the best choice for heli pilots looking to add the safety, security and clarity of Spektrum 2.4 GHz DSM2 technology to their aircraft while reducing the amount of on-board equipment and simplifying installation.
