    Mutant MAxx Chassis ??'s

    I recently purchased a Mutant Maxx chassis on Fleabay, It was posted as a JT Racing chassis. I was just about to purchase all the MP stuff thinking the chassis was a JT. Luckily I refrained and did some more research and found out what chassis is really used. I also understand that the MM chassis had a horrible gear ratio at the Center Diff.
    Does anyone know anyhting about this. Like what CD was used and what would be a good CD to use here. I would appreciate any and all help. My searches arent turning up the info I need. I appreciate your time and look forward to your responses!!

    What soo funny about this??

    Gearing is what determines this, its easy to retro spur gears for CD's. I am not worried about being over geared. This chassis will become BL soon anyway and overgearing would actually be good in that scenario to reduce the amount of trq applied at low rpms.

    ,the center spur is a 46T but there is one 55T for this chassis ,with the UE ultralite FR & RR diff you can take an hyper st ratio (11/43) .
    You can test differentials of almost all the TT 1/8 with different gearings, that makes many of reglages. My mutant chassis is not ended, I miss 2 ultralite diff cases, it is very light I am impatient to finish it

    are you talking about the JT Mutant or the Hardcore racing mutant chassis?

    the HCR chassis is the one with the center diff gearing problems. not the JT chassis. the HCR chassis uses a center diff from a GS SUT buggy. this is the where the gearing problem comes from.

    the JT chassis uses all MP diff parts and tmaxx diffs. your good to go here.

    It is the HCR Mutant Maxx Chassis. I have actually found a place that supposed still has the CD, Tank, Shafts and all for this chassis. But its $239. I have read in a couple of threads talking about swapping the diff gears and that helps the problem tremendously. I Plan to modify a spur gear with a larger tooth count if needed and run as low as a 16t c/b. If this doesnt work I will switch to the 1/8 diffs and play with the gearing. I just didnt know what CD and shafts this chassis uses.

    Thanks above for the constructive info, this is what I was hoping for as a response. Every RC has its weak links, this hobbie is all about making them you own and stepping outside the box. I will do this here. If nitro doesnt work out the massive amounts of torque a BL motor will produce will love the tall gearing.

    I appreciate any and all help to those that are willing to be constructive!!

    Well I found 54t and 58t Spur gears and may try a 13t c/b for a storm buggy. It actually isnt that bad. Piecing the parts together is only about $150 or less. Keep your fingers crossed for me. I am going to jump in head deep. If the gearing is too tall I will go BL LOL!!

    if all goes as planned I will only have about $300 invested in this set up. I had a bunch of parts from my bash maxx that made their way to this chassis. I would rather build it then buy it. Although the new HPI 5T is pretty tempting as a RTR

    how is it that you are changing the spur gears? the center diff used on the HCR chassis can not be changed unless you change the whole diff. i have been told the hot set up was 12/13CB and the center diff off a GS Truggy.

    i have both the HCR chassis and the JT chassis.

    I've had both and just my opinion I think the JT is a much better set-up.

    The JT chassis is far better than the HCR chassis.

    that is the same chassis i have. JT also had a eariler version that did not have dual brakes on the center diff. the other version had the disc only on the front of the diff.

    Looks like yours is the aluminum chassis and his is Ti.

    I hopefully have a full storm I am picking up here to finish it off. I will fiddle with gearing if I dont like the response and if that doesnt go how I want, then comes the BL set up. This is actually a HUGE part of why I like this hobby. The wrenching is 1/2 the fun.
    Here are a few pics and the new body I just painted up for her this weekend, this is only my 3rd attempt at painting my own body. I am pretty proud of it
