Graupner MC-12 R/C Computer System 40 MHz 4725.G -Gold Edition-

LIMITED GOLD EDITION with transmitter battery NiMH 2500 mAh - only as long as stock lasts!

A 7-channel computer radio control system with multi-soft software, with refined top-quality technology and rotary select set-up system with 9 model memories.
8-bit computer system ensures excellent reliability, simplified rotary programming system for straight-forward programming and setup.

High-contrast multi-data screen makes displays visible even in brilliant sunlight. Screen displays include input data for mixer functions, adjustment values, directions of rotation, trim values, programming information in the case of multi-function programs, and transmitter battery operating voltage. High-quality radio control system for F3A, F3B, F3C, F3D and F3E models; also a fine handheld transmitter for RC cars and model boats. Compatibility with standard FM and FMsss (PPM) systems. 9 model memories with automatic transfer of all essential programming and set-up parameters.Mixer systems and accurate variable end-point and centre points of all servo travels make the system perfect for the demanding user of model aircraft, boats and cars. Real-time processing (RTP) system with direct display of parameters. Multi-function software menus with 2-way rotary select system (RSS) for ease and convenience of programming. Normal rotation for standard processing, express rotation for fast-select system (FSS). Convenient mode selector switches quickly bet ween stick modes 1 - 4 (throttle right/left). All mixers, adjustments, reverse and memory data are transferred automatically when you change mode. Complex but easily set-up basic multifunction fixed-wing programs for F3A, F3B, F3C, F3D and F3E (ready-made programmed multi-mixer units, which can be supplemented by 3 additional freely programmable mixers; mixer inputs and offsets are variable, and mixers can be turned on and off by means of external switches). Super-heli program for standard, Heim and 120° swashplate systems. Programmable reverse function for all servos. Dual Rates for 3 servo functions, programmable for 2 positions using travel expander, available range 5 to 125%. Sub-trim memory system for offset centre point on all servos; also useful for adjusting to old servos, or servos with non-standard centre pulse width. Single-side servo throw (separate travel adjustment for both end-points of all servos), adjustment range 0 - 150%. This new facility makes it possible to program symmetrical and asymmetrical servo travels, e.g. to cope with a special application or compensate for a warped wing. Integral computer alarm system.
