Dauntless
100 TW
As engineering types go, I make a damn fine Cultural Anthropologist, which is my approach to about anything. So I just keep reading and reading and reading about the Turnigy HXT motors and others like it. I have a definite idea about these exploding controllers. (Which includes the desire to avoid them.)

This pairing is intended to run a large RC offroader. Not a plane turning a propeller, a truck, etc., with at least a little of the similar loading as a bike. The motor is 1,350 watts, 18.9-22.5% as compared to 6,000, 6,500 and 7,000 for the Turnigy 8085, 80100kv130 and kv180. And yet the controller is just about the amperage of 160 amp Castle people are swearing by. The smallest controller I'm finding people using for that particlar capacity of motor is 90 amps; those using it are told that's not big enough by others using 120 amps. Who in turn, are warned of their own deficiency by those with 150 amps. I just think these people are as close to being the experts in the sensorless motors that we'll find. An RC car just has to be considerably more responsive than an electric bike, so the bike needs even more latitude. Hobbyking as a new "Monster" that says flat out it's not to be used for a bike/scooter.
Sounds kind of like houses of straw, sticks and stones. The 8085 might hold up with a 200 amp controller, to my understanding as high as Castle goes. The two 80100's might like something bigger. http://kellycontroller.com/kbl4830124v-48v300abldc-controllerwith-regen-p-257.html
But you don't have to listen to me, maybe you LIKE blowing up all those controllers. I notice the giddiness with which it gets discussed around here.
