may I add the following I heared at the International Toy Fair in Nuremberg / Germany?
Graupner developped the HoTT System in its own laboratories in Germany, not in Korea. Graupner's former chief of development (Ralf Helbing) now is the head of Graupner/SJ Germany. To push the Trademark 'Graupner' the Korean company 'SJ Incorporated' has changed to 'Graupner Co. Ltd.' The European branch keeps the name 'Graupner/SJ GmbH'.
In my opinion the HoTT system was the first GHz system with an extensive telemetry. In this time a Futaba representative at the International Toy Fair in Nuremberg said to me: "why does a model airplane pilot need any feedback channel or telemetry system?'

Today I know not any pilot who relinquishes at infos of range limits, charge status monitoring and so on, and also the model tank scene has recognised the benefits; especially when using LiFe drive batteries. Leaving the range limit is more a problem for RC pilots than for tank drivers; but battery charge status, temperature of motors / ESC, critical threshold warnings and so on are very helpful when the tank is 'on mission' in grounds that are not reachable by a 'recovery service'
