Ho fatto una ricerca web ed ho trovato solo questo .. pochino lo so e magari già lo conosci .. in compenso te lo ho riportato in modo meno più schematico ..
The Magic Box is a unique unit which opens up a large number of new possible applications to the demanding RC modeller.
A single servo function can now control up to four servos, which can be programmed separately and accurately for direction of rotation, travel, centre and end-points, and the settings stored permanently in the unit.
Any of the values can be changed and re-stored at any time.
Typical applications include parallel control of up to four drive motors, different travels with only one servo function, various flaps on model aircraft, and much more.
External battery socket with gold-plated contacts.
Servos connected to the unit can be powered by a separate battery.
Sub-trim: neutral range offset.
Adjustment range: +/- 25%.
End-point adjustment: settings either side of neutral variable separately, adjustment range +/- 25%.
Travel adjustment: overall servo travel can be adjustedseparately for each servo over the range +/- 50%.
Servo reverse: the direction of servo rotation can be selected separately for each servo.
The unit is simple to operate using selector switches and plus / minus buttons.
Total reset function: all settings can easily be reset to the default values.
Quadruple computer Y-lead.
All outputs programmable individually.
