  Its a hacker C50 acro motor, I think they finalized on the 13 turn motor.
  It's geared 6.7 to one, and he's using 10 series, 3 parallel thunder power
  lithium polymer batteries. That comes to 42 volts unloaded, the fai max I
  believe, and at 68 amps at full throttle it's about 34 volts, or equivalent
  to 35 or so nicad/nimh at that level. Total capacity is 6150mah and flight
  time is about 20 minutes. At first, 4-parallel were being used, but since
  close to 1/2 hour flights weren't really needed <G>, they went down to 3
  parallel and tested to see that the packs could handle the loading, which
  they can. full throttle is 2300 watts, which equates to a bit over 3
  horsepower, but with the larg prop, thrust is far better than you get with a
  lot more horsepower with a "little" 18 inch prop.  Lots of research went
  into this, and a couple of us have been testing the C50 motors for almost a
  year (I flew one of the originals in my funtana at the TOC demos). I'm using
  the thunder powers in most everything, so 20 to 30 minute flight times with
  my 3D planes is common (some are 48" span, "40 size", and some are 80~88
  inch span, so they're not little parkflyers).
