how would i make a emaxx race worthy

[mp7maxx]

i was wondering how to make my emaxx better for racing. mainly lowering and on a budget of 150 to 250. im going to be racing at rat raceway in colorado ratraceway.com (http://www.ratraceway.com)

since you race on dirt you may want the 40 series bowties with the velocity rims and the 23mm hd adapter. also Rpm arms all the way around. they have a lifetime warranty. titanium skids. maybe a servo skid. maybe new rpm bumpers if your others are getting worn.

[tec_41]

Legend, those are all durability upgrades that add unwanted weight. If you want to race, you need some new shocks. Proline Powerstrokes would be your best bet. Bowties are good tires for racing on hard packed dirt...but if you are going to be driving on any loose surfaces you should look into the Sportraxx tires. A high torque steering servo helps a lot as well. Oh, and a couple nice sets of batteries ;)

well if if races he wants durability and how much more do rpm arms way than stock? dont get aluminum it will bend. If you get into a bad crash you will want durability.

[metalry101]

E-Maxxes are plenty durable enough stock. RPM arms are good, but if he's on a limited budget, he can wait. Tough parts improve durability for sure, but the best durability improvement that any truck will ever have is clean driving. If you can get around the track without hitting anything, you don't need tougher, heavier parts.

For racing, I'd leave the shocks stock as long as they're fairly new. Unless there's a big jump somewhere on the track, the stock shocks should be fine for the time being. If they're worn out, then replace them, but if they're fresh and don't leak, you'll be fine.

Grippy tires and lightweight wheels (Traxxas wheels are cheap, light, and strong) are important for racing.

Also, cut weight elsewhere. Slam your body as low as it'll go and cut the body posts, trim the bumpers (especially the rear) and the skids (again, especially the rear), don't run the gear cover, pull out first gear if you don't need it (you'd need a helluva tight track to need 1st gear on an E-Maxx), and if you pull 1st gear, pull the shifting servo.

Pull the pre-load spacers out of the shocks to get the ride height lower, and maybe try some stiffer springs (like Trinity's light blue ones), depending on what works at your track.

Get some 7 cell packs, and experiment with gearing. My personal favorite is 20/66, but that'll depend on the track.

I would highly suggest some good heat sinks for the motors, especially if you're only going to be running 2nd gear. Cutting some holes in the grill or the windshield can help airflow (it's not just for nitros any more).

If you've got money left over, a good high torque, metal geared steering servo and a worthwhile servo saver will help out your steering a bunch. For the servo saver, I'd suggest the Kimbrough 124. It's a lot better than the Traxxas servo saver. As for servos, I'd probably try something like a 625MG. They're only like 37 bux, they're a little bit stronger than stock (94 oz/in, which should be plenty with lightweight tires), and a lot quicker (.14 or .15), which is what you really want for racing.

If you can afford it later, a decent computerized radio with end point adjustments, digital trims, multiple model memory (different setups for different track conditions), dual rates, etc, would be a wise upgrade. If you're only running a single speed truck then you don't even have to go 3 channel. You could go with something as cheap as a Futaba 2PL. I believe they start around 70 bux, and they're hundreds of thousands of times better than the stock Traxxas radio. That's not a necessary mod to start out with, but eventually it would be a wise upgrade.

why would you take the gear cover off? hes not racing on pavement that will just allow more dirt to get in the motor. the covers there for a reason

[metalry101]

Not to flame, but you're not familiar with the E-Maxx at all, are you?

I've had one for over 4 years. They're closed endbell motors, and no dirt is going to get into the motors through the motor plate. If dirt gets in, it's going in by way of the vents for the fans.

The gear cover is meant to keep dirt and such off of the gears, but 32 pitch gears don't care what's in their way usually. Unless he's running on a very, very loamy track he'll probably never have any chunks of dirt big enough to stop the truck's gears. He doesn't have to pull the gear cover, but I don't run one. Not running it allows infinitely quicker access to the pinions for gearing changes, to the slipper for adjustments, and to all of the gears for setting gear mesh. Also, notice where the gears are located on the truck. You have to do some pretty amazing stuff to get large chunks of dirt lodged in gears on the back side of the tranny while going foward.

bulkheads @ hingepins # 1 in the break list 4 me.

[metalry101]

They are fairly brittle...ish. It's pretty hard to break stuff on an E-Maxx because they're not as fast as a T-Maxx. Honestly, you really have hit something hard to break one.

Honestly, good bulkheads are a wise investment, but on a limited budget, spending money on practice time at the track is a much better investment than a bucketload of aftermarket parts.

[Legend_Car]

im familiar with one i just know that if you get ahh whatever im not gonna argue because i wont win. besides i dont think its a good idea to leave it off when all the guys with emaxxs at my track run em on

[metalry101]

It's a preference thing. Running it is never a bad idea, as it will keep rocks and dirt out of your gears. However, I feel that it's too much of a PITA to take on and off to be worth it if I want to change the gearing or adjust the slipper or anything like that. I don't run the cover on mine and I don't plan to change that any time soon. Some people won't drive their trucks without it.

But The way I play I got to keep my cover on LOL Thay need the make a quick relese cover.

I guess other vehicles like most 10th scale gas trucks (GT, Losi, Mugen) all have completely exposed 32 pitch gears and they don't seem to get jammed. So I'll have to agree that running without the cover on the EMAXX probably won't mess up the gears.

[mp7maxx]

thanks my track is preety tight and has a huge jump. my budget now is like 300 dollars.
