The Jeti Model Mezon Evo 70A Limited Motor Run controller is specially designed for the lowest possible weight. This series is not in a metal box and is intended primarily for glider models where a continuous motor run is limited to a few seconds followed by a cooldown of the controller. The SW of the controller does not limit the running time, it only monitors the maximum temperature to prevent the controller from being destroyed by overheating. It is the pilot's responsibility to ensure an adequate mode of operation.
