They just paved my streets. Emaxx question?
 

Running an emaxx on a 7XL mostly on a paved street. I could get up to full speed, turn the wheel and have it do a 180 and bring it back. They just paved the streets and I am getting some serious traction now, but its flipping over on just about every turn. Anyone have any recommendations besides making it go slower? My body is taking a beating here.

I thinking about moving the shocks one position down to make them longer?
Maybe thinking about some E-revo wheels/tires which seem to give a little?

Or should I just get an E-revo and it will be more stable and forget about the maxx?

Or was it all just a good dream and these things arent supposed to do 180's on pavement at 42mph?

The erevo does handle better than the emaxx. Your street must have been very slippery. My blacktop street next to the shop will easily flip a truck at 20mph...

Ya it was a slick dark grey before and now I'm looking at a thin layer of black tar that they put on top.

lower the truck, lower the roll center. add some camber.

What shocks are you using? You could move them so that they are more vertical, soften the springs and get a roll bar. The Revo does handle better.

I'm using the stock shocks.

What tires are you using? I bet if you install the stock chevrons you won't have any flipping problems :lol:.

Pretty tough to overcome the laws of nature. The only way to do a turn like that at that speed to completely overcome the forces of friction and centripital forces. Slicks and/or dropping that thing to the ground.

Ya I'm running the stock chevrons. They just slide all over the place. I think traxxas did it on purpose. I tried the tmax new 6.3" tires for a while, but it would flip with those so I went back to the stockers. They have much more grip and are horribly unbalanced. I really dont know how the t-maxx guys can keep that thing on the ground with those tires.

My shell and the body posts are just taking a beating right now.

Get some RPM offset wheels and Proline Mashers with a hard insert and tape the tires. It will reduce the bite and be a little more firm for less tire roll. Also, if you are using the stock red springs, take all the spacers off and let it sag. Set the shocks to the lowest ride height and see if that helps.

no, you want to do the exact opposite. giving more of an angle will make the vehicle more forgiving and stable all around.

Also, giving more angle will make the shocks "softer" and more progressive.

Thanks for the info guys. I looked at the shocks and I moved them out so they have more angle like Andrew32 said. I guess if you adjust them at the top you make them more verticle, at the bottom put them more at an angle. I didnt realize there were spacers in there but I could have just taken them out.
Turns out I had a busted lower A arm and I didnt even know it. The turnbuckles were keeping everything in place. Guess I should check the truck more often. I spend so much time researching power plants for these things I am a bit lost on the basics.
I did try it out with the new shock spacing and it runs much better. I can turn on a dime again at 3/4 top speed. I'm not going to try top speed until I replace the lower a arm. If its still a bit squirrley I will remove the spacers.
Thanks again.

Put the shocks on the most outer lower mounting positions and most inner on the upper positions, remove all spacers, and hope for the best! A set of 1/2 offset rims would widen the stance abit and that'd help to. A set of road specific tires such as the road rage tires would also help. Of course if your considering getting a different vehicle that would help too! The Maxx series handle like crap and IMO are a PITA to work on. The REVO is a much better handling platform if you want to stick with a MT however if you're just going to be running on the street I would suggest a different route all together! A Truggy may also be a good alternative as they have large tires and decent ground clearence to handle off road but they also have a much lower COG.

I wouldn't call the Revo an MT, more of a truggy with big tires. I would get a 4-Tec or something for the street if thats all you do. I got a couple buggies so I only run my brushless Maxx now when I play on my track in the back yard. It never sees the streets anymore.

There is a fine line between MT and Truggy but the REVO is a MT. A Truggy has a plate chassis with everything mounted on top of it, much less ground clearence and lower COG. A REVO has the diffs below the chassis, more ground clearence and a much higher COG.

Duh... thanks for the correction. He is right more horizontal for stability with a soft setup.

haha no problamo. Its easy to get them mixed up. dude i set up a 1:1 race car and got my camber mixed up and the car looked like this \ /...20 minutes befo our sponsors came in......:oops::oops:

whoops :rofl:

Try some on road radials like the 8th scale belted ofnas.

LRP tires and rims
Lower Truck
Wider Truck
Slower Speeds
Dont Turn so sharp :lol:

Took out the spacers and man the thing turns on a dime now. I can do a 180 at top speed again. Thanks for the ideas. I may try some of the others as time permits. So I guess the only downfall is that I really cant jump it to much now as it seems to bottom out qucker.
I'm guessing a truggy would mean another nitro conversion. I have done several of them and am just kinda burned out on it. As much as I like running them the emaxx is the only vehicle I have ever put a brushless motor on that hasnt fallen apart from the power of the motor. My nitro conversions have also gotton pretty expensive and the maintenance seems to be a bit more.

good to hear you can do a 180 at top speed. i can say you were still lucky to go 3/4 throttle and still do a 180.
im running a 7xl as well geared for 44mph. with my setup, i can only go like 15mph on turns on concrete. any faster any itll flip. i have stiffer springs and thicker oil. when i tried using the stock springs, the sag was CRAZY. i dont know how you can run your truck with the stock springs. i have lipos so its lighter than nimhs. i guess the chevrons have very weak traction or something. im using the losi zombies and they have too much traction.

Yeah I have noticed ever since I made those changes I do have quite a bit of sag, but its the only thing that keeps it from flipping over so I will live with it. I bought another emaxx for doing some offroading and am using this one for street running only. Too bad we cant have the best of both worlds.
The more I look at my new street I hate it. The stuff they put on top is like sand paper. I'm starting to notice the tires getting worn down and chipped, where before I was running without a problem.
