FYI: 200Kv motor info

    I have been running the 200KV motors in my GT (AT) for about 9 month. Daily riding, with frequent sustained speeds of 26-27 mph.

    I started experiencing, about 3 months ago, where 1 motor would not engage when I accelerated and I would have let go of the accelerator to get it to kick in.

    Yesterday accelerating through and intersection the board just locked and I stacked pretty bad, bruised ribs and some road rash.

    Upon inspection, one motor is now basically seized, turning it is very difficult. The board will not power on at all. I took out the motor controller and found that about half of the connections from the 4 big black capacitors (8 connections) on the board had basically disintegrated. It also looks like 2 of the capacitors may have vented. I'm guessing the motor not engaging was probably 1 or more half disintegrated connections having intermittent contact. Not sure why it seized up like this.

    But it's pretty clear that excessive use of the 200KV motors basically melted/disintegrated the capacitor connections, and who knows what else.

    Also, comparing this controller with a different motor controller (same version on the PCB), they have a different configurations of those 4 capacitors. Each has 3 85C and 1 105C capacitor, but the 105C one was in a different spot on each board. I am interested if anyone can explain why this is, or if it matters, etc.

    thanks,
    Rick

    Has anybody tried these 200kv with the higher torque belt and wheel pulley?

    I wonder how much torque you get back using the upgrade after losing torque with the 200kv motors...???
