Hi, I've been into r/c for the last 15 years but have no clue about brushless and lipo setups. Ok I have a e-firestorm I wanna juice up a bit. any idea on a sweet combo, and also do I need to change my gearing? I already have a Hypersonic 4600 6.6v pack and charger on the way, cuz I found a sweet deal on ebay, but I think the pack is a little wider than the space provided on the truck. Do I need to strap it down or use some type of velcro to secure it? Thanks everyone!!!:

You plan on racing or just all out fast and bashin? The mamba max 5700 seems to be a very popular combo for the bashers. It can handle a 3s lipo and go balls out fast. I have the 6900 mamba max which is higher kv, but will not handle 3s lipo. If you go brushless, you really want a high quality (maxamps for instance) lipo and never look back. I have a rustler and upgraded gearing and what not. The mamba seems to take to gearing well and mine doesnt have heating issues yet, you just gotta use common sense with your gearing/terrain. I have their 6000hv 2s lipo and with that and my 6900, it has done 55mph so far with stockish gearing. I have a lot more testing to do with gearing combos. If you plan on racing or want super smooth take offs then I'd recommend a novak GTB system. Somewhat on the pricier end, but they do make nice stuff. I have first hand experience with the 13.5 for racing and their fast 3.5r. That 3.5 is really fast with a good quality lipo, wow. I have yet to clock that, but with proper traction, it should waste my mamba using similar gearing and battery. The 3.5 is like 10,000 kv and will be limited to 2s lipo maximum. Their speed controllers are functional for racers, but are limited to 6 cell nimh or 2s lipo. Where as the mamba max controller can handle up to like 12 cell nimh or 3s lipo. Mamba combos are about half the price of the top of the line novak packages and have a ton of raw power, not to mention you can hook up the esc to your pc via usb and program in settings and adjust the throttle and brake curve. It's not as smooth as the novak or other sensored systems, but it seems to be a really good value for the control and tweakability you get. It all depends on what you want it for and how much you want to spend, but dont skimp on the battery. I'd recommend a MINIMUM of a 4000 mah 2s maxamps, but the 6000 if it fits is a nice battery, provides plenty of amps and has good run time. Just read around about proper handling/balancing techniques and you'll be golden. And as for gearing, I don't know what it comes with, but you'll probably want to gear it down to begin with, but you're best bet is to start low and go up from there, I'd say start out 4 or 5 teeth down from stock (pinion) and see how you're temps are. I can gear mine pretty low and have just awesome all around torque and speed while runnin super cool. And when Im doin on road speed runs, I can gear it up pretty high and be within safe operating temps. I notice you're transmission has metal gears which is nice, that will come in handy with the power. My trans. ratio is 2.72 and geared 13/90 which is really low, almost the lowest I can go, I still have better than stock speed and tree stump pulling power, hard to keep front end down. I've gone up to 23/83 when I clocked it at 55, low end didnt really suffer, still hard keepin the front end down. Im gonn try 28t pinion and go for speed if I dont overheat it. My good all around gearing is 17/83 or 90. Top end is still mid 40s and cool temps, good for playin in dirt. But your trans. is 2.6, so it'll differ as what gearing choices you want to use. Just giving you my personal experience with it all. Sorry for long post.
