Outrunner info??

[BrianG]

I was downstairs looking at my unfinished Hyper 8 buggy (waiting for cash) and was wondering what my next project was going to be. I still keep drifting back to a custom dragster/musclecar idea. I thought maybe using a direct motor to rear diff drive system using an outrunner motor may be nice for this. I wouldn't be using a spur/pinion setup nor a transmission so the only reduction would be in the rear diff.

I went to a LHS today and checked out what they have for outrunners and discovered I know nothing about them. Well, I do know the rotor is on the outer can, that they typically run much lower kv, and they have huge amounts of torque. But, I don't know what the ideal max rpm is or really any way to compare them to a typical inrunner style, power-wise.

The guy at the LHS said the model numbers (of whatever brand they have) are what they would equate to if it was a Nitro motor. So, a 46 motor would be equivalent to a .46 size Nitro motor. That really didn't tell me a whole heck of a lot. I then asked him what the typical max current draw is and he said the 46 (~800kv) draws upwards of 60A at 11.1v in a plane. So, I asked him if that was constant draw or pulsed draw and he wasn't sure. Also, if 11.1v is the recommended voltage for that motor, then does that mean the max recommended rpm is <= 10k?
