Brushless Savage Help

Hey everyone,

I have been running a BL savage for a year now, and only today found this forum. I did the conversion myself, and shoe-horned in an E-Maxx tranny (with steel idler gears), and a Novak HV-Maxx BL system. I'm running it on
12-14 cells in a brick format:

The truck is running 6.9" Imex K-Rock tires, and an ulgy Parma Garbage truck body.

Lately I've been having a tonne of glitching, overheating, and cogging issues with the HV-Maxx set-up, and am such am looking to upgrade to a different and more powerfull BL set-up.

I've read a tonne of posts on this forum, and it seems that popular choices are BK/Feigao/Wanderer XL motos in either 9 or 10 turn forms. Is this a good choice for 12-14 cells?

I'm looking for something that will definately out perform my HV-Maxx set-up, without being undrivably insane. I like to go fast, and wheelies can be fun, but most of my driving is off-road bashing. I'd like a good all around setup that I can bolt up to my current E-Maxx tranny.

For an ESC I was thinking of either the BK 12020 or 9920.

Any assistance or direction would very much be appreciated.

Thanx!
