Yokomo MX4 restoration project
1 Attachment(s)
Hi guys,
First post in the car section as I haven't played with 4 wheels in a while. I found my old MX4 which I loved dearly but everything is 15 years old. Nicads and brushed motors. It was a missile and won me a lot of local club races but I'm guessing now it is antique. To change to lipo / brushless what kind of setup would I be looking for? I can look at a plane or heli and know roughly what it will need but a car I have no idea. I'm guessing I will need to supply gearing ratios for you to give me good advice towards kv ratings? Also, how would a modern car compared to my MX4? Thanks for your time and sorry for such an open question! Martyn |
The car doesn't really matter; the driver does. You could beat a two-thousand platform with that buggy if you know what you're doing. I'd say throw a a 11.5 or 13.5 in it.

Thanks! need to learn :) |
Right. Higher KV; More speed. Lower turns; More speed. Vice versa, too.
And, I don't want you stripping diffs and belts, so that is why I suggested that range. Powerful enough, but not too powerful. |
Thanks very much!
The MX4 is still stock with diffs gears belts etc so not a bad idea. To go really powerful do people upgrade them or is it just a case of more maintenance more often? |
The trick is to rebuild the diffs with love...
what that means is basically shimming the diff so there little back lash, little end float and its meshing correctly. what u need to do is remove the slop/play if that makes sense? its a good idea to do this to the whole chassis not just the driveline. there is a ton of videos on YouTube that are for other vehicles but as long as it's the same style of diff the procedure will be the same. if u need help finding some I sure we can help |
For starters it might be worth striping the car completely down and rebuilding it from ground up... With love...
Been a older car u will have to rebuild all the suspension from suspension pins to shocks. But pay the most attention to the suspension pins and holes for the suspension arms, aswell as all the ballends. I dare say the metal and alloy parts will need a good clean and a light polish |
With love? I don't do that. It might be why my MERV's diff gears strip even after shimming them. :/

No that's because it's a traxxas lol
|
OOH *shots fired*!!! You better get out of here before the Traxxas Kids get in here.... LOL!
