Spektrum AR7100 & AR7100R DSM2 Heli Receivers w/Rev Limit

Over the last two years Spektrum has risen from stranger to stardom in the RC Helicopter arena.  Previously a big name in RC Cars with their synthesized radios for mostly surface that have now revolutionized the RC Radio as we know it.  Their latest arrivals to the market in the last few months have been the AR7100 & AR7100R.  The “R” designation meaning “Rev Limit” onboard.  Thats right! The AR7100R has a built in regulator AND rev limiter/governor.  The 7100 has the regulator but no rev limit feature.   This kind of combination technology is definately going to push the limit of the electronics manufacturers to come up with some better “Black Boxes.”  What would be a hot combo would be a combination receiver, regulator, gyro, limiter, igniter topped off with DC charging circuit for the flight battery.  That would be a hot offering……..I like that name “The Black Box, ” or even an Align version called the “All-In-One.”  What about a V-Bar version of the same unit.  Nice.  What’s next GPS and Wi-Fi programming?!

Overview

The AR7100 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 AR7100 to be installed in the best possible configuration for high-performance heli’s, 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 2.4GHz DSM technology to their aircraft while reducing the amount of on-board equipment and simplifying installation.

The AR7100 and AR7100R offer the benefits of multiple components in one compact unit, keeping your installation neat and simple.
