- Vario with altitude signals and climb and descent signals- Additional warning thresholds for min. height, max. height, climb and descent speed in two steps- Altitude display and storage of the min. and max. altitude.- Adjustable warning time: OFF, 5, 10, 15, 20, 25, 30 seconds, always- Adjustable warning repetition time: always, 1, 2, 3, 4, 5 min, once HoTT- is the synthesis of know-how, engineering and worldwide tests by professional pilots. A 2.4 GHz system that points the way for the future of RC model making.HoTT- Hopping Telemetry Transmission is safety with up to 75 channels HoTT- uses frequency hopping spread spectrum technology. (FHSS)HoTT- offers integrated telemetry in real time (expandable).HoTT- is fully programmable with the help of the Smartbox.System Features:- Simple and extremely fast binding- Range test and undervoltage warning function- Extremely wide receiver operating voltage range from 3.6 V to 8.4 V (functional up to 2.5 V)- Failsafe, free channel mapping- Binding of any number of receivers for channel expansion (max. 32 channels)- Up to 4 servos can be controlled simultaneously in blocks with a servo cycle time of 10 ms (Digital servos only!)- Maximum noise immunity due to optimized frequency hopping and wide channel spread- Extremely fast rebinding, even at maximum distance- Telemetry evaluation in real time- Future-proof due to update capability via USB interface
