Your gearing sounds right. Is that a new motor? Had it been overheated at some point? What are the odds that the cheapie batt packs are dropping voltage so badly that the amp draw is getting that high?

I didnt think of the voltage drop issue. I'll retry my tests later with my good lipo pack. The motor is used, so who knows what temeratures it has reached. A motor thats gotten hot could draw more power? I did notice the wires to the motor were a bit warm, could a bad solder joint between the motor connector and wire cause excess amp draw? Everything else looked good. It rolls real nice and the mesh is good. Tires are just standard 1/8th scale tires/rims.

Ok, here is what i did. I charged up my new 5000mah lipo packs (2x 2c packs in series) and ran some tests. Even with the good packs, i was getting up to a 135 amp peak draw with the wheels off the ground doing a couple quick full throttle bursts. Now that may have been for only a split second as my amp probe was set to display the max drawn. I swapped in my mamba max and was still getting a peak of 125. For the heck of it, i pulled out my ofna 9.5 conversion ( Fiago 8xl finned can with Mamba Max esc) and got a peak of 55 amps with the wheels off the ground which seems more like it. Id like to just throw it on the ground and not worry about it, but these esc's are expensive! Any thoughts?

Can i make a cable myself to interface the bk with my PC or is that something i have to buy? If it has the options the mamba has, i figure that it would be a good idea to to turn some things down. :)
