After nearly 4 years of development, Scorpion has released the new model 12-cell HV ESC's to the market. These speed controllers feature a new ultra PC Board for maximum shielding, and ultra-low internal resistance which helps to make these ESC's some of the most efficient 12-cell controllers available. Heavy Duty power MOSFET transistors handle the most demanding applications for electric powered models including larger 3D and IMAC type aircraft and the extreme 3d 600 and 700 class electric helicopters.

These new controllers feature on to the best Governor modes in the industry, for rock-solid headspeeds. This is especially important for flying in competition F3C type helicopter events, where maintaining a consistent head-speed is crucial. Also featured is an exceptional soft-start mode for extremely smooth spool-ups in your competition or scale helicopter models.

These new 12-cell Speed Controllers also offer a unique wireless programming system that is a first in the RC Model Industry. Unlike other ESC manufacturers, who require you to buy an add-on programming module to gain full functionality of the controller, Scorpion provides a full feature Programming Card with EVERY speed controller sold, at No Extra Charge!

The new wireless programming system consists of a postage stamp size IR receiver module that mounts in your model, and a credit card sized IR Transmitter that easily fits in your pocket or toolbox. The IR receiver plugs into the throttle channel of your radio receiver, and then the Speed Controller plugs into the IR Receiver board. To program the ESC, you simply flip the switch on the IR Receiver board to the program position, point the transmitter at the IR receiver board, type in the parameter you want to adjust and hit the Enter button. The IR board will give you a flashing light and a motor tone to acknowledge the command. Once you are finished programming, you simply flip the switch on the IR Receiver board to the Run position. This will re-boot the ESC and enter the new program into memory. After this is complete, you can fly your aircraft.

Programming your ESC has never been easier! There is no need to dig the receiver out of the plane, No need to unplug any cables, and no more dragging a laptop computer to the flying field! Programming your ESC is as easy as changing channels on your TV!

The adjustable parameters on the Scorpion 12-cell ESC's include many extra options not found on other controllers. These options include:

Low Voltage Cutoff: Adjustable from 12.0 to 48.0 volts in 0.5 volt increments
Brake Setting: Adjustable in 5 steps from No Brake to Very Hard Brake
LVC Cut-off Type: 50% power, Pulsed Output and No cut-off are available
Motor Acceleration Delay: Slows motor response for use with gear box motors. Adjustable in 5 steps to 0.15, 0.30, 0.45, 0.7 and 1.3 Seconds
Current Overload Protection: Can be turned on or off to suit your preference (turning protection off will void your warranty)
PWM Frequency: Set to 8KHz Khz
Soft Start Mode: Slows down motor spool-up for Helicopter use, available with or without Governor Mode
Motor Timing: 6 options available, Auto Detect, 5°, 15°, 20°, 25°, and 30°
Governor Mode: For Helicopter use, 11 gain levels available
Starter Boost: For starting very High Kv motors that can be difficult to start, 5 levels available
Soft Start Duration: can be set to 10, 15 or 20 seconds

Scorpion Speed Controllers also include all of the ESC parameters clearly labeled on the heatsink assembly. Voltage range, current rating, BEC rating, and input polarity are all clearly marked to avoid any confusion. Scorpion 12-cell Switching BEC Series Speed Controllers are also backed by a 2 year manufacturers warranty against defects in materials and workmanship, so you can buy with confidence. For a total package of Quality, Performance and Value, you can rely on Scorpion Brushless Speed Controllers.
