Just saw this on my Hot Bodies Lightning GT:





Because HB parts are hard and expensive to get here in Germany, can I just use other cups??

Thanks..

ebay

OK... But how about an answer to the question - will other cups work??

if they are the same size

Aha....

I see.




Theeeeeennnnnn maybe I should re-focus my question... Which other cups are the same size as those on the HB Lightning series??

i dont know about the lightning truggy because the cups are actually attached to the diff.

look on page 17 i think

Why not swap the cups to the opposite side...that way you get twice the life out of them...

Just had a closer look at the manual... I have to take the entire diff apart??!...

That's how pretty much ALL diffs are built.

Take your rear dogbones out and test-fit them into Savage diff cups. I think the ball end on the Lightning cars are too small to work with Savage parts, though. I'd wager good money though that Kyosho diff cups will work.

What's kind of dumb is, I think the diff is OK, but the cups are going fast with this engine... I recently took my old Savage 25 apart, and don't think I'd ever be able to get those diffs back together.. I DO have those cups there though..

And I do know that ball at the end of the Savage bone is too big to fit in the HB cup..(that just sounds perverted...)

Anyway, if I get some Kyosho cups or whatever, when I take the diff apart, am I gonna have to shim, etc?? Cuz if so I'd rather buy a whole new diff.....

you shouldn't have to shim them. If worst comes to worst, HB DOES sell entire assembled diffs, but I'd just try going after the Kyosho cups first and foremost. the diffs aren't hard to put together, just read the instructions
