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?!
