Vitalis :
I'm considering swapping out the E-Flite Power 15(950KV, 5.4 ounces) with 4S passive system in my Caprice (Classic ) for either an AXI or Cobra . Since you have already done a lot of research, what is a comparable motor with, of course, a lower KV rating ?
I plan to go 6S with an Active timer; possibly Igor's system. The primary considerations ,as I see them, are weight, KV rating and ability to swing a 3 blade . I believe that a 9" or 10" (at most) with a 4.5 or 5 pitch three blade would be about right. Need to find out who is producing carbon fibre props of this size that are suitable for our purposes.
Thanks
