Default Which sustainer system would you chose for your sailplane?

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,

SLB


Luka:

Since the prop now automatically stops in same position each time, does
this mean that the cross section shape of the fuselage at the nose no
longer has to be circular, but instead could be oval like on many
gliders? This would require the spinner to be oval -- does an oval
spinner shape present problems?

I second the idea of better information in one place on the web page.
Right now, anyone wanting accurate information must be a sleuth who
reads multiple webpages, who reads a PDF brochure, and who peruses RAS
postings by Luka and others. Sherlock Holmes, we need you!
