The Arizona Heli Regulator is specifically designed with RC helicopters in mind. It can handle very high currents, in very demanding environments. It has two separate voltage outputs: 5V for the gyro, and an adjustable 5 to 8.00V for the receiver…allowing better responsiveness for the digital servos not associated with the gyro system. It also can act as a solid state switch, eliminating a mechanical switch in the power path. The solid state switching uses a 'pin and flag' system, so there are no moving parts in flight.
Pinflag system is pictured at the top of this page.

To the Left is a very basic lay out of an Arizona Regulator, Receiver, Gyro, and Battery. Click on the Link below to check out a true Engineering diagram.

Translating Power

The Arizona Regulator is rated in Watts, because the current limit moves, based on load. These limits are affected by battery voltage "droop" as it is loaded, and the voltage setpoint of the adjustable output. Current limits are shown to the left (based on power)*, for a regulator with the adjustable voltage at 6V (red), 5.5V (pink), and 5.0V (purple). Note that the higher output voltage means the regulator does not have to work as hard, and therefore the current limits are higher.

The Heatsink

Like the Arizona Regulator, the heat sink that the Arizona uses has been designed from the ground up. Fromeco designed the Heat Sink from scratch using thermal modeling software. Each Heat Sink is milled (not extruded) to our specs, and then anodized Fromeco Blue. The Arizona Heat Sink is a critical part to the Business End of the Arizona Regulator, and allows for the harshest 3D flying imaginable in any ambient condition, on Earth!

The Cat Splint

Dubbed by Fromeco the "Cat Splint" for lack of a better name, this piece of Delrin plastic with rubber grommets helps to isolate the Arizona Regulator from the equipment rattling vibrations that Helicopters have. The Cat Splint also serves as a mounting aid, slits for velcro strapping have been relieved into it's sides. A picture below and to the left shows a Cat Splint mounted on an Arizona Regulator. All Arizona's come standard with Cat Splints, so no need to ask for one!

Conformal Coating

Fromeco utilizes an "Open" board configuration on the Arizona. This Save weight and space. The Conformal Coating protects the Arizona from the elements, Nitro, Oil, and Dust, each Arizona is Conformally Coated. Pictured on the right is a closeup of an Arizona and it's Conformal Coating.

Plugs

Arizona Regulators have five leads total, an Input "Blue", Deans, or Power Poles (not Pictured), a Charge Lead "Black", a Switch Lead* "Neon Yellow", a Gyro Lead "Green For Gyro", a Rudder Lead "Red for Rudder".  Of Course Fromeco knows there is no "Gyro Lead" and no "Rudder Lead". Green is Gain, and Red is for the Tail Rotor Servo. We just call them that to make things easy to remember.

*The Pin Flag switch has a matching Neon Yellow Female jack, (Pictured at the top of the page). A normal "Off the Shelf" type switch will not work in place of our Pin Flag switch unless certain modifications are made.

Voltage Adjustment

To the left is a picture of the Voltage Adjustement pins that come on each Arizona Regulator. The voltage adjustment pins allow the end user adjust the Receiver voltage between 5.00Volts and 8.00Volts.
