Thanks.... I guess ill have to get a few more Losi cars to use 100 screws

they go faster than you think I just ordered my third set. Very nice car by the way.

You guys crack me up!!

I've just spotted this over on TC, Looks like a real nice buggy - & you've done a super job on the clean-up

@ RCveteren - I thought that all the JRX2 cars had the 'thin' shock collers? - and it does seem that the earlier cars had black collers & later they became grey. As for for the solid (No holes) rear tower, these seemed to only appear on very early cars - I have two Jrx2s that both have no-stamp motor plates, but have the usual rear tower with the holes.... only one of those cars has the aluminium spacers on the gearbox outputs.... confusing!

I also have one with no stamp, but holes on the R shock tower, and alum spacers on the outputs.....and thats how it was from the box when I bought it new in '89-'90.

Somewhere along the way as I understand they went to the wide collars as shown in this thread.

And yes, the no hole shock tower is the very early one with no engraved motor plate. Then it switched to the holes on the rear shock tower but still included a non engraved motor plate, I have one each of these new and as a side both had aluminum outdrive rings as well.

It probably doesn't matter, but aren't the Associated 8-32 screws 100 degrees and the Losi screws 82 degrees? As in, the angle where the inferior aspect of the screw head rests in the countersunk holes in the chassis?

It's a load bearing consideration. If you run 100 degree screws in an 82 degree countersunk hole, only the outside of the screw will be resting on the outer rim of the hole.

I think that screws designed for aluminum chassis are 100 degrees (like Associated) due to the thinner plate and more shallow countersink. Thicker composite chassis allow a deeper countersink and use of the 82 degree screw.

I'm sorry to bring something up to make everyone paranoid and wondering what kind of screws everyone is using. I've certainly lost some sleep(!).

Yeah - i'm just not sure if they ever made it onto the X2? - I think they first appeared with the release of the Pro & maybe made there way onto the JRXT, i've just never seen a new-built (from kit) JRX2 with the wide collers.... that said I maybe (read probably) wrong

You could be right, I am not sure how to confirm that until someone opens a new X2 box and finds them. I have a new in package shock set which has the thin collars.

Well, just noticed the box art car for the JRX-Pro shows the thin collers, so I guess the wide ones were never included in JRX-2 kits
