Dogman,
I got the same hub as methods. I have the pedal start 20Amp 72v controller, and it seems to require at least 5mph to start, even though ebikes says it only needs 3Kph (1.8MPH). I had a similar problem with methods in riding down a hill in that when the coast speed exceeds the no load speed of the hub (around 31MPH), the controller kicks into a heavy regen mode (feels like a rough braking). Without some torque control, this could cause axle spinout. I didn't get a spinout, but I noticed my nuts did loosen slightly. I'm not convinced this is normal behaviour, and suspect the controller has some defect. Methods found that one of his phase wires was not making good contact. In my case, all the connectors look solid. I measured the resistance through the lines to the controller from phase to phase and measured 209 ohms. Nothing seemed unbalanced. I'm still waiting for Justin to get back to me with some testing. it appears that not everyone has this issue, but because the 2806 hub has such high torque, it would make sense that it would generate higher reverse current when coasting down a steep hill at high speed. My watts' up meter doesn't measure reverse current, so I don't know what the actual reverse current is. i might try wiring it up in reverse to see what it is just for testing purposes.
