Hmm 64 amps and 1200 watts? Thats like 18.75 volts on a 6 cell pack, near terminal voltage! What would be nice is to see some RPM figures correlating to the amps/volts readings.
All your figures are showing a cell voltage under load of less than 3.5v which is pretty bad. What was the temp of the packs when you tested them? I suppose we shouldnt be surprised, I see this all the time at our field with Flightpower packs, they sag out under even a mild load and are a complete waste of money IMHO.
Our 6 cell setups sit around 22.5v under a 52A load using chinese made 4000mah 25c cells, this is with a Midifan rotor and thrust is around 2.3-2.4kg. Even when I am testing hotter setups at 70A the packs are still holding 21+ volts at close to 1500w.
Will be interesting to see some video of the Hawk, should be a real parkflyer
