Mine was also loose in rear, good now. Main changes I made were:
  • Stand up rear shocks one hole
  • Same sway bar front and rear (1.2mm)
  • Lengthen front camber link (inner position on camber plate) + increase spacers to 2.5mm.
  • Same springs front and rear TOP 306 (17lb)
These changes address 'loose' rear end, I'm running 17.5 boosted and rubber tire / low grip asphalt.

If you are really struggling for grip, try lengthening rear camber link to inner hole on camber plate.

Good luck with it !

Cheers
Alan

I was fighting a push initially so I kept the front short.

Provides the most ackerman adjustability otherwise the steering links start to get too close to the arm mounts. 1mm Max shim could be possible in the front end.

you need to get 6 flange bearings and you have to add small shims for in side between the bearing and flat washers...I can tighten screw down with no problem...
PS the total of shim have to be perfect thickiness

Okay, the EX has been out for a few months now. Deciding whether to upgrade or not. Besides the sloppy steering and shock spring collars, what are the pros and/or cons of the EX.

Can we know the size of the flange bearings please. Eager to try this.

Thanks

Default EX

big fan of the Top Racing brand. Owned a Scythe, Photon, Sabre, Rebel and now busy with the EX. First page of build, shims missing?? wtf, after searching for an hour figured they not there. Now I have everything on the chassis and already stripped 2 screws using decent tools.
I hope all this frustration is worth it in the end.

Missing diff shims, suspension arms are shimmed .5mm short, yes shock collars and sloppy steering, and screws are still not all quite fantastic quality.

But, generally it's got good build quality where it counts, and the EX develops a heap more rear end traction and steering out of the box than the original Photon did.

After driving mine a while now, I also dig the new motor mount, the sort of floating spur drive pin in kind of neat, diff is good once it stops leaking, fine adjustment things around the car are also good (sway bar locater etc).

Spur gear and pulley though is harder to get out then in the old model, apart from most related to it, those new forks that center the sway bar stop you being able to slip off the belts, also I don't like the lack of a 'neat' battery strap option, and to be really honest it's just got too many holes related to servo mounting, if I did cut down the 'bump' I'd just have an ugly half screw hole, which is dumb.

None of that take away from it being a great car though.
