Panhard mount (Possible) weak point found

[$uicide $hift]

So I let my neighbors son try out the SCX10 III. Unfortunately he went for a dirt cliff about one foot high but was pretty much a straight up incline. The front right wheel hit first pretty hard flipping the rig.

The end of the panhard bar that mounts to the axle housing broke from the mount. The place you screw the panhard bar into that is molded into the axle housing broke. So instead of a hole to thread a screw through it is a C shape now.

This currently to me is a poor design. The SCX10 II the other end of the panhard would break. Why would you design this tiny plastic hole to screw the pandhard mount into as part of the axle housing? This breaks and now the entire axle housing needs to be replaced instead of just getting a new mount part to attach to the axle.

I realize this was a bit of a hard hit and I am not upset it broke. I just feel that there is a better way to mount this so that it can be replaced easily....

Re: Panhard mount weak point found and it is not good

Axle housings are only $9 thankfully, which is cheaper than the shock tower set with the replacement panhard mount for the chassis. Handing the remote to a kid is always going to be precarious.

Oh absolutely I agree 100%. I knew there was a chance for something to happen.

My son has the SCX10 II and broke the panhard doing a jump. I ordered an upgraded aluminum mount with shock hoops and it has not been an issue. On his rig though the other end is on the knuckle, easier / quicker to replace. You could also just get an upgraded knuckle. I am not into the metal axles so this is now a part that cannot really be upgraded to take a bit more than normal abuse.

On the 10.2 the pan hard is part of the C-Hub, with these being single piece axles (like some of the 10.2’s) we don’t have the option to upgrade the C-hub yet, until the aftermarket comes through. I’m anxiously waiting for that. (C’mon SSD!)

Overall the 10.3 is sturdier in practically every way vs the 10.2, thanks to the materials and the design, but there will still be failures like all rigs. Hopefully just not as common or expensive to replace.

Breaking parts on a new rig is always a tough pull to swallow, I feel your pain and frustration there. Hope you get it back up and running soon "thumbsup"

Oh I agree, I still love the SCX10 III. This does not take away from the fact that it is the best crawler on the market at this time IMO. I just wish there was a mount part attached to the axle rather than the mount being molded in.

I have already ordered the part. I will tear the axle down so it is ready for replacement when it arrives. "thumbsup"

Hilarious...and so true! Roo's stay-at-home trail of destruction thus far includes the motor (ripped the end bell out of the housing ?!?!) and ESC (torn loose from its mount, causing the power switch cable to rip out from the board) on his Granite, broken shock shaft on the Granite, blown ESC and two driveshafts on his Stampede 4x4, and a short-circuited saddle pack battery for the SC10 4X4. :lmao:

To the OP, seemingly innocent tumbles can sometimes produce an impact at just the wrong angle to cause something to break. A $9 replacement housing is quite reasonable all things considered. I've tumbled my 10.3 a few feet down a hill several times during testing, and so far, no breaks. If we start to see a pattern of breaks in the same location, that would be an indication that there may be a design or material issue. But it's a bit early to go there.

Oh you are right that an innocent tumble can break something. He actually was not doing too bad. I do believe it was that the right front tire caught first and it was pretty hard. I was not surprised to see the break, I was just surprised that the axle housing needed to be replaced instead of a bolt on bracket. The cost is cheap, I am just lazy and for that part I was just surprised that the entire housing needed replacement.

I agree that it is too early to say this is going to be seen by many. It was not my intent so I adjusted the title. Already have the axle apart and just waiting on the new housing.

Would this not be covered under the 2 year warranty? Granted it will take longer to get a replacement, but at least it will be replaced. IDK just a thought.

 

[Inspector86]

I don't think the warranty would cover a kid driving a truck. I have heard others complain about the panhard bar being a weak point.

 

[kincer]

This is the third different time I've heard about this, I'm sure someone is gonna come up with something to address this, I haven't even got mine assembled yet, the way it goes for me there will probably be a updated part or upgrade by the time I get to it :lmao:

 

[nalby]

Well it's a weak point, I have a alum vitavon panhard mount and I guess something had to give.

 

[Mental180]

Mine just broke same place with no notable knocks was reversing at speed and it just lost control and when I looked it had broken the panhard mount off the diff housing.

 

[drburns]

I've had a couple of panhard issues with mine too. I broke both the mount on the axle (today) and the panhard mount on the driver's side (thankful the spare was included). Both times were average high gear tumbles, nothing too crazy. The other issue I ran into is how the panhard bar installs according to the manual. The frame mounted bar end hits the servo arm and limits travel when fully compressing the right front suspension. The panhard bar actually bends upward when it contacts against the servo arm. I also spaced my servo up a bit to gain clearance but it didn't help. When I flip the left side bar end and bar 180*, I get tons of clearance and full suspension travel with no binding. I'm convinced the first broken panhard mount was because of the suspension binding up. Could there be an error in the manual about how the bar mounts?

 

[drburns]

Actually just found out that’s not a spare mount; it’s for non portal axles. Either way, it seems to work with the bar flipped. Also explains why it was hitting the servo arm. Didn’t realize it wasn’t a spare. It’s a slightly different shape.

 

[svt923]

I have it on good authority that a better panhard mounting system than 3mm of plastic is coming soon.
