Going BL on my Savage

[suicideneil]

Yep, the more turns a BL motor has, the cooler (but slower) it will run on the same given voltage. 10XL will run slightly cooler, and you can gear up more as a result (within reason though), so perhaps that would be a better setup than the 9XL. The Quark monster pro is also called the 125b since that is how many amps it can handle (burst rating is about 200 ish); it is the smoothest esc going at the moment, but it just has one annoying problem. Inside the esc case the FETs are connected to a heatspreader (slab of aluminum) via some thermal transfer tape, and then connected to the inside out the case using some more tape. Since the esc isnt sealed, dust & dirt find their way inside the case and cause the tape to fail. When this happens the FETs are nolonger connected to the inside of the case, and heat cant escape. As a result the esc starts to thermal after just a few minutes, but the outside of the case still feels cool. GriffinRu has some nice photos linked to in his sig which show one method of performing the thermal mod. BrianG shold be able to provide some diagrams too (they are floating around somewhere on this site).

EDIT: If you can wait until Feb, the MMM system will be released (hopefully), and that would be even better, especially at less than $300.
