R/C technology has been growing at a breathtaking pace and we are pleased to present the next generation, Graupner/SJ's HOTT technology and this, the all new 9 channel MZ-18. It is all too easy to call a new product revolutionary but this radio breaks all the rules to present a system so comprehensive that it is causing the opposition to sit up and look!
HOTT has been built from the ground up to take full advantage of modern telemetry technology. HoTT is the fastest growing radio brand in Europe, due to its superior features using Graupner/SJ’s unique 2.4GHz ‘Hopping Telemetry Transmission’ bi-directional protocol. HoTT radios use two way communications to give ultra-fast high resolution control combined with live telemetry data direct from your model. Telemetry options include signal strength, altitude, airspeed, climb/sink (vario), fuel level, receiver battery voltage monitoring, individual Li-Po cell monitoring, engine temperature, RPM, GPS position and many more.

The MZ-24 puts the HOT in HOTT, leading the way in radio control technology. A beautiful styled radio incorporating a 3.5” colour, user friendly, touch screen display. Fully equipped with a 30 model memory, smart voice announcement, multi-binding system, and advanced HOTT wired or wireless trainer system. With Real Time Data Analysis (with optional sensors).

If you don't need more than 9 channels and the MZ-24 is too big a step then this, the MZ-18 is just what you have been looking for. The absolute very best at an unbeatable price. Look no further, you won't be disappointed.
