IISI - Telemetry

The Iisi system is a model data telemtry system for controlling model specific parametres like current, voltage, capacity, temperature etc. Iisi is independent from radio brand or system and works independend from that. A data telemetry system in electric helicopters is especially for giving exact informations about the used battery capacity, for example in photo helicopters, scale hellicopters or peaceful flown machines where it is difficult to check the battery voltage with giving pitch. But also in 3D helis it is a wonderful tool to check each cell during flight and not to overstress the batteries. An additional method of use is as controller for finding best maximum pitch for or cyclic deflections for the individual setup. For wing airplanes it is fine for finding the best propeller.

Just after the first avoided empty-battery-crash the price for Iisi is more than equalized.
