Iam getting a E-MAXX soon and was wondering something. On the Traxxas site the chassis has 6 slots for batteries. I want to use 7 cells with the truck but it only has 6 slots. Is this true or did they not update the site? Does the chassis come with 7 slots now?

Thanks:)

the chassis has never had 7 cells. there is somewhere on traxxas's website where it shows you how to put the 7th cell in but basically it sits toward the middle of the truck almost up against the trans case pointing front-to-back in the truck(90 degrees to the other cells....

yes, the XR3 CAn be modified to work...BUT if someone is going to buy a radio anyway...for the about same money you can get a controller that does not have to be modified to do the same work AND void the warranty

Most everyone that races runs their packs inverted on the underside of the chassis. So it's really easy to mount a 7th cell. Simply trim out one of the center battery slot dividers so there is a hole just large enough for a cell to set up through the chassis in a normal hump pack configuration about even with the tranny to help keep the weight centered.

If you are still running your battery packs in the stock, old mounting possition then just let the 7th cell set down through the chassis on the underside.

Thing is, iam running 3000 saddle packs not sticks

Well, yeah, thats what most serious racers are running. That's why I said just cut away one of the strips between two cells and let the 7 th cell set through the chassis. Would pictures help?

it would help but i already did it the traxxas way. i like the traxxas way better becaus i can still run them in my xxx-t

Oh, I see. Although most folks that race stadium truck run side x side packs rather than saddle packs. But anyway, here's what I was talking about.

Showing where one of the battery supports is cut out.

This shows how the 6 cells ride on one side of the chassis and the 7th cell is hump pack configuration.

Here's a shot of mine with wheels at full lock. If your truck is like this and you still need more steering I don't know where you're going to find it. The suspension arms won't allow much more.

U can do more than just mess with your steering to get it to hook up. Try putting your Front shocks to the outer hole, this will increase front traction and help you turn a little better. Try increasing ackerman or camber. There are many things you can do to get your truck to hookup. Ive seen those things hookup better than my xxx-t sometims and they fly. Your truck setup is just off.

Unless you do some major modifying or you have some aftermarket steering system you can't adjust the ackerman on an E-Maxx. The draglink is a solid flat bar stock.

Moving the shocks to the outer hole will give you more sidebite but not more steering. It will also make the truck less forgiving over rough sections and tend to be a bit twitchy.

Increasing rear toe-in will help make the truck turn quicker but don't over do it. Also makes it a bit more stable under hard accelleration.

Increasing front camber will lose you straightline traction due to the unequal length swingarms. As the truck transfers weight to the rear under accelleration the nose raises, which increases the camber considerably which reduces the contact patch of the front tires with accellerating.

Usually the truck understeers in corners when on throttle. Usually because the inside front tire is lifting and unloading. Then the outside front wheel stop's pulling and becomes dead weight to be pushed through the turn. Tapping the brakes sets the inside front back down but you lose forward momentum.

Better solution is to run the rear shocks with heavier oil for more pack to keep more weight from transfering to the rear. And a rear sway bar helps if the track is fairly smooth and even with a lot of bite.

Its all about the throttle finger my friend. Try going to softer springs to make the car "roll" more through the corners

Okay, not that it matters at this point but exactly how long have you been "racing" your E-Maxx and what kind of lap times do you turn compared to lap times you get with your XXXt?

My setup on my Maxx yields lap times nearly equal to A-main stock truck times where I race. What kind of laps are you turning for comparison sake?

I used to with a T. Setting up a xxx-t is just like setting up a maxx (same principles used). But you have a advantage with 4wd, u have to remember this after this because the xxx-t is 2wd and is harder to drive. I race Mod xxx-t and i have the 2end fastest lap times a nitro xxx-nt beat me by 2 sec. I also race onroad mostly but i am gettin back into offroad. How long have u been racing?
