Tried it out. The position of the sensors is critical. 1/4" retarded, and it will try to start in either direction, then buck around and not run. 1/4" too advanced and even in no-load it trips the breaker on the 26amp 84v power supply. The motor also gets very warm very fast, even with no load.
On battery power, even at 84v rather than 42v, it feels weaker than the RC controllers, and the top speed is LESS ??? Feel like it hits a limiter or something.
The current shunt is not modified, so it should only be pulling whatever it's set to pull.
The throttle response is the deal breaker. It's a HAZARD. I don't even have a chain on my pedals, so I rely 100% on the motor, and this is not safe in traffic or trying any sort of spirited/technical riding. 1-2 second might not seem like a lot on paper, but when you are trying to negotiate traffic, it feels like an hour, and it's not safe.
Overall, I'm pretty pissed. If this "soft start" can't be solved, I'm going to throw out my 12fet and 18fet boards. What a bunch of work to make a soggy feeling terrible to ride safety hazard. The last RC controllers at half the voltage felt 100000times better for the 10mins before they exploded.
