I have noticed the same thing. In my instance, the bearings are very smooth until the axle is inserted. That tells me that the plastic inserts that hold the bearings don't locate the axis of the axle properly. Basically side loading the bearings when you force the axle through. That causes these plain bearings to bind up a bit and feel gritty. I have tried many different bearings and new plastic bit with the same observation. You can feel the bit of resistance as the axle is pushed through the bearings. It seems a bit better with the 3mm (centered) position though.

OK, I understand this and it is exactly what I experienced. What can be done to align the bearings to reduce side load on the bearings. I would like to have a one piece spindle to eliminate this issue. I am really loving this chassis and this is the only area that I feel needs some attention. The old architecture was very good for bearing alignment.

I am going to look at this tonight to see what I can do.

Do you have the updated crush tubes?

Could be the crush sleeve issue.... I slipped a .02mm shim between the crush tube and the axle (using the axle with clamping hex) and all side load and bearing issues solved

The other night I noticed mine felt gritty. What's the length of the updated crush tube?

I think it's .02mm longer.

Do you remember what the original value was by chance?

Default Schelle battery strap

For my in-line setup I was looking for a way to eliminate the front battery spacers and Schelle came through. Know I can move my battery forwards and backwards without having different size front spacers. Quality is top notch and and it does what it advertised.

Well got the rest of the goodies installed... Atleast until my FT bearing kits get back in stock. I also have a set of Acer Ceramic Bearings to compare to the FT kit.

After installing the Exotek Axles, Triad Slipper, CB Cut Gears, D4 17.5 and FT Motor Plate it came in at 1533g RTR

I noticed today after I installed the new parts that it seems to pull to the right pretty hard on heavy breaking. Does it a little bit on heavy acceleration also but not as bad. Any ideas??

I also have all the RM Arms F/R as well as the tower that I am debating on throwing on to see. I run high traction clay at IRCR and have read that the RM arms work really well on the high bite stuff.

I am pretty happy with the weight where it is at right now. Just hoping that it doesn't mess with the setup too much because it ran really well.

I hope you mean 0.2mm. 0.02mm seems too small.

Go with this

The FT setup is good too, just heavier. It seems a lot of people have slop in the front hub assembly. You can CA glue your inserts in place, I would recommend buying spares so you can have a glued set for 2 3 and 4mm trailing. By upgrading from the stock setup you will help take a lot of that slop out, and your bearings won't get gritty as fast.
