I stripped the center of my rims clean! Circles!!! Bye Bye stock!!

Looks like I get to throw my RPM's on there now ;)

Has anyone complained to HPI directly about their poop ass rims and this problem? If so, what was the result?
 
how are your rpms working?..... I'm gonna put some new rims on mine also looking at the big joe 40s (velocity rims)
 
Good luck with the rpm rims Çh®i§tiªñ. But they did not last me very long either. Now I have got some hardcore alum. rims on the way! There not going to strip out! Yes there is a down side to alum. but I'm not going to keep on buying rims after a couple gallons all the time. And yes my rims are always tight.
 
What I want to know is why has there been any problems with the T-maxx wheels stripping out?
 
I have only stripped out one stock Savage rim. My RPM Monster Claws have held up, but they looked like they might go. My IMEX Jumbo Maxx rims have not shown any sign of weakness. And believe it or not my stock T-Maxx rims have not shown any sign of weakness.

To answer imnotsure's question, the problem lies in the tolerance of the wheel hex. The Savage wheel hex has a wider inner diameter to take the Savage axle, but it is a slightly smaller hex than the T-Maxx. When I say slightly, we're talkin' on the order of parts of milimeters. It is just enough to allow an engine with sufficient power and wheels with sufficient traction to force that hex through the plastic...a lot like a router blade. The end result is a rounded out hex socket on the rim.

Several people have applied JB weld to their hexes and the rim socket to great success. I personally think the problem lies in the rim not being sufficiently tightened onto the hex. Without a little loctite the wheel nuts back off and allow the wheel some horizontal play giving the hex even more room to work on the plastic rim. Others have gone the aluminum rim route...I think too much weight is added, but that is just me.

It's about time. I can't believe that you've benn puttputtin that ride around for this long. Start beating that thing. Here's a tip, lean the HSN a tad, and drive it like you stole it.

As for somplaining about the rims, that's a marketing ploy. Planned obselecence.:hehe:
 
lol Error. THANKS!

I'm thinking I can just use the Dynamite hexes and grind them down 1-2mm on the thickness. Maybe that will help. Have the JumboMaxx, RPM's and stock Traxxas as well as aximizer Beadlocks to throw at it. I just dont want to burn them all.....

This Piccos just has too much balls! Is that possible?????
 
Yeah, the Picco ROCKS! I'm running the HB clamping drive hexes. I'm also running 2 sets of HB rims, 2 sets of (God forbid) T-Maxx rims and a set of HB Jumbos. So far none of these rims shows any sign of wallowing out the centers. IMO, HPI has a serious problem with their rim design. I wouldn't worry about other rims, whatever you end up with (barring HPI rims).
 
You would have to drill out the center of the T-Maxx hex. The inner diameter is not large enough to accomodate the Savage axle.
 
OK. Are the stock Savage 21 hexes plastic?

I just picked up a Savage SS today and the hexes are a metal alloy. I'm wondering if the ones with the SS are updated hexes.


Chris - let us know how the Maxx hexes work out!! We'll have to get together after I finish building. :D
 
No...the stock hexes are some weak ass alloy. It might be aluminum, it might not.
 
So how about after-market aluminum hexes? Should I just go out a get a set and save myself the greif, or is the problem with the rims??
 
Drink more beer, the supply of stock HPI drive hexes is getting low.

I shattered two when we were bashing Sky, and that was with the Hyper 8.
 
The problem is both the rims and the stock hexes. The stockers are too soft on both sides (rims and hexes). I recommend getting the aftermarket hexes, and try a different set of rims.

If you want to save on money up front, wait until you tank a rim or trash a hex...then go and pick up what you need.
 
So far, I have been pleased with the HB locking hexes/ They show very little wear and remain on the axles when ya pull the wheel off, also no lash or slop when they're tightened up on the axles.
 
:violin: Ok, Since I got the SS, do you think it's a good idea to replace the rims to start with. I mena once you glue those tires on the rims they can be a real pain to geet back off. Do Tmaxx rims fit? if so I may have a set of Alum. "saw blades" that I could try.
 
I wouldn't even screw with the stock HPI rims. It's not a question of if they will fail, it's a question of when. With the 25 or Picco 26 engine, it won't take long.

T-Maxx rims fit just fine. I run 2 sets of those, 1 with stock tires, 1 with proline mulchers, and both have held up very well.
