A little history check.... I really believe the speed controller was the biggest issue with the tests done posted above. I have worked with other controllers since which are much better.
About the suggestion of Re-drive (previous post). As said above we were hoping for direct drive. As for sourcing.... no problem.... I make the Re-drive, cast and machine, see http://www.foxcon.com/Reduction-Drive.html
OK....now for an update
In Sept we tested a QS motor, 12kW rated vehicle hub motor. Rated to max 1480rpm and said to be higher than 350Nm of torque. While the rpm is lower than we wanted, thought it would be a good motor to run a test anyway.
Using the standard propeller on different pitch angles. Battery voltage of 155v.
28 degrees 1340rpm max 213A pull force of 84-85kg
23 degrees 1378rpm max 180A pull force of 84-87kg
18 degrees 1440rpm max 140A pull force of 78kg
