Well guess what diff fits the car? The xray X1 2016 car, but it is high priced..... trying to find one on a deal.

Save your money and just buy some -A ceramic differential balls, Square RC polished rings and extra Belleville washers. You can build up a beautiful differential with this setup.

A Thrust bearing is a must. If not, be prepared to replace your bearing every single run.

Not even exaggerating

Which bearing? I've have 500~600 laps with my FX with no issues with my bearings. Can you be more specific on which bearing we should watch out for?

Hes talking about the outer right side 5x11 diff bearing, they are not meant to be loaded sideways. If you replace it with the tamiya thrust bearing you dont have that problem.

As slotmachine said, Im referring to is the one inside the right side drive hub, just before the cone washes. Like slot said, in that particular situation, radial bearings are not designed to take an axial load. Depending on track, the bearing can be worn out in as little as one battery pack.

As many suggested, the tamiya thrust bearing seem to work well with the diff, but any 5x11x4.5 thrust bearing would work just as well. Ive ordered some from a chinese hardware store website for pennies each and havent found the need to replace it. Its typical to rebuild the diff after teach track session, but after that, the diff is buttery smooth again.

Well the diff has finally freed up. I found out instead of using a drill to seat it in just use the throttle at a higher speed and they smooth up and get a little bit more locked.

hi all...
ran the fx for the first time today.......after the first run (on new tyres) i thought what the hell is this???....just spinning every time i tried to go around the corner...

anyway after changing a few things ie esc and radio settings, the diff from 16 balls to 8 balls and back again, after all that finally got the car to my liking...so far very impressed (driver not so much)....anyway might look at getting a carbon rear axle and maybe changing the pivot balls to reduce the slop as shown on this thread but apart from that.....loving the car....

here is a pic of my livery and wiring layout......

No carbon rear axles available

I recently machined a titanium version. Made a carbon version but didnt like it. Just feel the threaded insert on the left side is not going to last. Will run the new axle Sunday if weather holds out. Just wanted to reduce the rolling weight.

Congrats on getting the car working Blade! It is so much fun working a car in when you first get it on track. It's really my favorite thing to do. ha!

AP, I'm chomping a the bit to get my FX!! I have read through this entire thread, twice now.

Did the kit have the correct pivot balls when you opened it?

Again though, pumped to start putting this one together. . . Think I'm going to take my time on this one, as I have several other F1's and no one is really running them right now around here, and build it slowly and correctly. Seems like that will make a difference. Usually put a kit together in a day or two.

Pics of the carbon axle and the titanium one installed. The Ti version was turned down between bearings to get the wt down to the same as the carbon one.
