Ebay for a 'cheaper' ubec, but cheap often = nasty. I hope you have upgraded to FLM hybrid bulks & HB diffs, 3.3 drive shafts and good quality centres, steel idlers& locked the tranny into second. If you havent done all that ( and more ideally ) you are going to end up with a really nice BL setup in a really weak truck. At the end of the day a stock Emaxx is not designed for any kind of BL power- read around the Emaxx & BL sections and research the upgrades done- then you will have a better idea of what you are dealing with.

Another option is the HV4.5- drop in system that just requires a few minor up grades. Its better for noobs since although it doesnt have anywhere near the same torque, the motor can still get you up to 40 mph quickly and it can run at higher temps/revs (though not a good thing, it can take it better than some setups). Good batteries area must though.
