DB-01 front hex's

[Hog]

In between finishing my last race on Wednesday evening, and checking over my car today, one of the front hex's has snapped in half and is binding up the drive to that wheel.

1. Anyone know where I can get some replacements?
2. Why on earth didn't Tamiya go for the more common 12mm hex favouring a tine 10mm version? Does seem like a poor deisgn as the hex's are hardly "robust".

Cheers,
Dave.

I've had exactly the same problem!! Tried everywhere, then I someone showed me this:

These guys are good, I ordered 2 pairs, took about 3 days from payment to my order arriving.

Hope this helps.

When I first built the car, I thought the hexes were plastic pieces, so I just put the pins on the axle and snapped the hexes on. The hexes are actually metal, so they were obviously not meant to bend back and forth like that. Then I realised you were supposed to mount the hexes first and then carefully align the hex holes with the axle holes and push the pin through. Since I started putting them on the proper way, I've not had trouble with them.

Not to accuse anybody else of being as dumb as I was, but just thought I'd mention my experience with them.

As I understand it, the front hex size has been pretty much standardized among competition 4WD offroad buggies. There are only a few out there that have the oddball touring car size hex (Kyosho), and they offer conversion hexes.

I'm well aware the hex goes on before the pin, but it really doesn't seem man enough for the job in hand. The whole hex is no more than 2mm thick, of which half of that is drilled out for the pin. Surely it would have been wiser to have a thicker drive hex and alter the wheel offset?

I have run mine all year, since the car first came out, and never broke one (5.5, lipo and high grip circuits). So I dunno what you guys are doing to snap one, except if you haven't tightened the wheel nut before a run, the hex jumps half a flat, then you have tightenned it.....

I busted one of mine, when my gorrilla grip over tightened the wheel nut. Yes I know I'm an animal!! Lesson learnt though

Yep, this noob snapped both of them also...didnt realize the pin goes on AFTER the hex . Lesson learned, the new set have yet to break, but I have a spare set just in case.
