The large ones were smooth when i pop them in, its the two small ones that go inboard that are tight. You can try popping them on and off until it loosens up.

Thats how I got mine to free up.

I'm nearly finished building my f104 and just when I went to test fit my IP 3800 lipo that fits everything. It doesn't fit lucky I have some old stick packs. Are there any corally plug packs that fit? If not do I just have to get some stick pack lipos?

Also I may have asked this somewhere but what is a good 64 pitch pinion/spur combo for silver can?

Thanks

around 93/27 60mm tires, rollout should be something in the mid 50s, i think

yes you might need rounded lipos, dont think the square sided ones fit / plug

I put those inner pivot balls in a dremel and slowly sanded them with 1200 grit. Butter! However, be careful because you can easily sand off too much material.

Use a spare arm and a spare ball to test with, sand down the ball in small increments until you find the right size (sorry I don't remember what the measurement was, sold my car) and then replicate on the rest of the pivot balls.

tamiya makes low friction pivot balls. they work really well. they are a hopup item.

What equipment do you use to true your Tamiya tires down?
Are you trueing your tires after each race, or is there a need for new ones?

Yeah that's what I was thinking on doing but didn't want to go through the hassle if I didn't have to.

I tried the pop the arm on and off many times and it still has not loosened up...plus I'd have to do that every time I change the arm which I'd rather not do.

The low friction ones might be a solution but unless they have a threaded stud on them I'd need to lock tight in a long set screw. On my F1-09 I used a threaded stand off to make it easier to open the top deck.

The old 'squeeze ball cups with needle nose' trick works good for this;

Yes, what the good fellows said about too much pod droop and also try tightening the center shock collar a few turns too in case your center ride height is dropping down too far.
