Dualsky vs new custom made motors

I’m just wondering what are the advantages of the new custom made motors over previously used Dualsky GA6000.8 motors. They look pretty strong and suitable for this application (based on listed specs on manufacturer’s website).

A few reasons,

  1. More efficient by about 15%
  2. Half the weight of the duel sky
  3. Higher quality internal components

Great. Thank you for the explanation.

Could you post the specs of the custom motors please? Such as max voltage & current, KV rating, internal resistance & weight?
