    e revo going for 90mph+

    bought myself an e revo mamba edition.

    using traxxas 3s lipos
    my goal with this car is to get it to about 94 mph (150kph)
    my fastest run so far is at almost 60, about 59 so really close hehe.
    video here.


    made the run with 18/54

    next run is going to be with 25/54

    Hi Snook, Your rig looks pretty similar to mine. Your running (2) 3s lipos correct ? I have the same Road Rage tires also. I see yours are ballooning a fair bit. Are they taped ? Ive herd you might need a set of XO-1 wheels to get those speeds. But I'll be keeping an eye on this tread to see how your makin out. Good luck brother, heres my rig. 18/54 also on 6s.

    25/54 - be careful man! Big repair bills await.

    I think you'll struggle to get to 90mph with smaller tyres - but I will following - good luck dude!


    Bash it like someone else is doing the wrenching!

    Good luck with this - definitely get it on video.

    The first mod should be to tape your tires. You are getting more top end from them ballooning but its causing tremendous instability at 60. You wouldn't be able to control the car at all if it was any faster with ballooning tires.

    MikePeperni hit 91.2 mph (see video below)

    Also lower the car to reduce drag. MikePeperni uses HPI Phaltlines which have a firmer sidewall. I'm not really sure if they are better for speed runs than Road Rages if both were taped (I have both but never got beyond 50mph). I also made my own closed cell foam inserts (from 3/8" thick yoga mat) for my Phaltlines which makes them even more stable.

    He'll just need to gear it up. I'd use mod1 gears 34/36 may fit.

    Erevo does look strange with x0-1 wheels though,








    I ran road rage wheels on mine as well, untaped since they were pre mounted

    Did 60mph easily with 17/40 mod1 gearing on 6s.

    Why would you need to cool down LiPos? The should not get much warmer than ambient temperature.

    mine were atleast in the 90's, after draining them with a mamba. 6s, traxxas 5000 lipos,, recharging now, dont worry though, i'll post my 100mph run when i tweak her. sick What i mean is, after running the mamba, the batteries were easily in the high 90s F. And i just wanted snooke to know he has some friendly competition let er rip!!!

    from my experience when i was doing high speed runs, and managed to get something above 70mph only...(geared mod1 24/36 with losi diffs)

    most difficult to manage:

    1. tires. phaltlines are better (less surface on the ground and vs the air). i think tape would help, i used fishing line which was breaking after 5-6 runs. balancing is a MUST
    2. batteries. you need the highest C rating ever trust me. i was considering putting 2 pairs in parallel because my 40c didnt cut it.
    3. weight is not important, aerodynamics is. act accordingly, really low ride height needed (tie wrap the rockers)

    its not easy at all getting 90mph.

    It's not easy to get the XO-1 to 90mph without incident and it's designed for speed.

    Good luck with the ERBE.
    Sure it'll work, watch this

    Ever crashed @ 75+mph? You will change your mind after a few crashes @ those speeds.
    No slipper/tall gearing/power = broken parts.

    Hopefully you can get your steering tightened up better than the one in the video.

    I saw a vid of one hitting a post at around 65mph, and there wasn't much left that wasn't broken. Reaching 90mph doesn't seem to be quite as hard as controlling the ERBE at 90.

    I sincerely hope your luck is good and the speed gods are on your side.
    Sure it'll work, watch this

    Hey Snook, do you have your suspension zip tied in the top pick ? Why does it look so low. Mines on the lowest setting for the a-arms and looks alot higher than yours does.

    Hey those Phaltlines are caving in because the HPI foams in them are junk. I made my own foam inserts from a 3/8" yoga mat (cut some strips) and they are way more solid and stable.

    That's for sure. Check out some of the videos of the XO-1s losing control and whats left of them after those high speeds. LOL

    BTW nice look'n rig OP. Keep tweaking, gear up, and watch your motor temps. You can tape your tires and also run O-rings on the outside to keep them from ballooning.

    DO'H.........

    I have heard that sound before........the body sliding across the pavement....

    foam tires or solid rubber, is the way to go. Lathe or grind off the rim bead. Then build or have built some rubber rings(tires) & glue them on the rims. Then you can set your "tire" dia. too.
    Would you go flip my truck back over??

    ^^ Exactly. I'm looking into 18mm square adapters to run 1/5 scale GRP tires. They are solid rubber. I'd also like to try the FG 1/6 scale slicks. Baja 5b guys run the FG slicks.

    Edit: I really like the idea of making your own solid rubber tires. Will be much cheaper than the GRP/FG route. You can buy sheets of rubber in various thickness/softness.

    The XO-1 tires will really help you reach the speeds your looking for. Just gear up for the smaller diameter.
