XD-4 2,4GHz TECHNO.INTEL.FREQ Graupner 3122 Professional micro-computer radio control system exploiting the latest 2.4 GHz technology, for the demanding pro-standard RC car and racing boat operator
No more crystals and channel selection processes: no frequency monitoring required - just switch on and drive!
Interference caused by electric motors, servos andelectrical charge effects (metal-to-metal "noise") is virtually impossible
Short 2.4 GHz aerial
Economical current drain, for longer running times and more fun
Accurate settings and highly convenient programming
Ergonomically efficient, technically up-to-date radio control system utilising 2.4 GHz transmission technology, for the demanding pro-standard RC car and racing boat operator
Modern computer radio control system with eight-bit CPU and FULLY DIGITAL ACCURATE TUNING (ultra-precise digital set-up and adjustment system) for three servos
Carefully positioned transmitter controls and ergonomically efficient case design for fatigue-freesteering
Large LCD monitor provides clearly arranged information relating to function parameters and set-up parameters; also digital display of the transmitter channel, model memory and transmitter battery voltage
Four-button terminal for programming and accurate set-up of desired functions and parameters
Four two-way rocker buttons for fully digitalsteering trim, steering trim rate, throttle trim, throttle /brake functions, and programmable positional function for the third servo channel
ESB (Emergency Security Button): momentary emergency button for fast, safe switching of important functions in emergency situations
PPN = PPM 18 (normal modulation) PPF = PPM Fast:twice the transmission rate = half the response time of the servos and speed controller
BAT visual and audible battery low voltage warning
MDL ten model memories for function data and set-up data. Each model memory can be assigned a brief model name
STC (Steering Centre Trim) steering sub-trim
THC (Throttle Centre Trim) idle sub-trim
STM (Steering Rate Master adjustment)
STG (Steering Rate Grip lever B) infinitely variable travel switching (Dual / Variable Rate). Reduction and enlargement of travels whilst racing, using two-way rocker button and additional emergency button for dual safety travel switching
EXP ST (Steering Exponential adjustment) exponential function for steering servo, range 0 - 100 %
EXP THF (Throttle Exponential adjustment) THF = throttle forward, THB = brake, range 0 - 100 %
EPA ST (End Point Adjustment Steering) servo travel end-point adjustment, steering left / right, max. 125 - 0 %
EPA (End Point Adjustment) brake end-point adjustment using two-way rocker button, max. 125 - 0 %
EPA TH (End Point Adjustment Throttle) end-pointadjustment of throttle THC and brake R/B
EPA F3 (End Point adjustment, function 3) end-point adjustment for third servo function
ST (Steering reversing switch) steering servo reverse
TH (Throttle reversing switch) throttle servo reverse
F3 (Function 3 reversing switch) servo reverse forfunction 3
TDA (Throttle Deadband adjustment) for throttle and brake function, separately variable start-point for the range of effect
Universal stopwatch 0 - 999 seconds, for wide-ranging time measurements whilst racing
Modern Lap Record Timer up to fifty laps with a lap time of 0 - 99.9 seconds. Useful for subsequentanalysis of important parameters per lap, e.g. motor, speed controller, drive battery, tyre and model specification
