Which sustainer system would you chose for your sailplane?

Renny, so you're running about 170 Amps or so. Your motor and esc need some cooling, so how is that accomplished? And then you must have a way to automatically override throttle if lipos approach 70 to 80% drained?







Motor cooling is handled via a small electric fan forward of the rudder pedals, an air vent in the nose cone that allows outside air to help cool the motor (and the cockpit), and 3 electric fans on the shelf behind the pilot's seat to cool the controller. When the batteries get low, warnings go off on the FCU, and I would then throttle back and turn off the FES. There is no automatic shutdown of the FES which allows the pilot to keep the FES running if there is an emergency situation. Thx - Renny



On our latest instalations, we manage to arrange cooling also without electric fan infront of pedals. Motor itself has bigger centrifugal ventilator at back side!

Luka,

It sounds like a number of incremental changes have been made to the FES system that have not yet been posted to your web site. Could you write a post detailing these changes and perhaps also let us know what's coming in the near future? Thanks,
