After watching LS' s video a few times now on his latest EZ spin motor, dose it seem to anyone else here that the efficiency is way to high?. Im having trouble believing that that tiny cap could run that motor at that speed for that long :o
Dose anyone know the value of the cap he is using?

  IIRC, he's using a 5F super-cap in the latest EZ spin video.

Note that Mark used a 1F cap for his 25+hour run.

Yes, but what size cap did LS use-dose anyone know?
It looks very small for the run time he was getting throughout the video.

... .-.. .. -.. . .-.
Seem to recall he used a pair of 100uF tantalums in one extended run.
It was within the comments to one of the videos.
I don't think tantalums are made at much larger capacities than that and are definitely where to head for low losses during run time.
