my bad, I was thinking XXX/XX4 and B4/B44 rear wheels.

That's fine... you would've solved a problem for me if they were the same... I was just pretty sure they measured differently.

I haven't measured myself but I'm pretty sure the hex depth of the losi is greater, but the backspacing at the base of the hex is the same. So while the losi hex seats deeper, the offset is the same. I run losi/proline(b4) hex wheels on my cars and while the thickness at the axle and depth of the hex is obvious, I have never noticed a change in offset.

Please correct me if I'm totally wrong on this. If I am, I cannot understand how companies are advertising wheels as b4/rb5/22?

Good question! Maybe it's small enough where each car falls within ROAR/IFMAR overall width spec regardless of the backspacing?

AKA, Avid RC, and Proline wheels are advertised as universal between AE, Losi, and Kyosho..

I measure from the back of the rim to the bottom of the hex, then take into account the width of the rim itself. Do the same for the AE wheels, and you can get a number. I use the bottom of the hex because that's where the hex from the shaft would sit, thus defining the width. The top of the hex is arbitrary -- if the hex is too deep, it will hit the hub... if it's too shallow, it'll just reduce surface area.

Offset = (Depth of bottom of hex to inside rim of wheel) - (Width of Rim / 2)

Assuming 70mm width, 36mm from rim to bottom of hex would mean you have a offset of 1mm (wheel comes in 1mm from center)

At least, that's what I would figure.. but like you, I could be wrong.

Even if there is a difference, you could possibly use wider/narrower hexes to account for the differences.

After all this talk of 14mm hexes and wheel offset someone finally brings to light the intelligent solution. Who cares what the car comes with. If you don't suck as a car builder you can pretty much run any wheels.

why not use the 2wd standard. Most all majors have a 12 mm hex. I am hoping they provide a 12mm hub option as well.

I have about 50 pairs of new Kyosho wheels with 12mm hex, thats why...

I love this hobby and have spent a lot (and I mean a lot) of money on racing multiple classes for 12 years+ So dont worry, I know it costs...

Might just be as easy as a hub change though.

But if 14mm hexes makes a better wheel then I m all for it.

Just get the cars released soon!

Xray makes 12mm hexes for their TCs, and they make them in different widths. So assuming the axle diameter is the same, there's your answer if you choose to use 12mm, you may need new pins too (also available for the TC!)

Car inspection....


Some nice paint work is required to make that look good..

Half of them aren't. I ran into this issue with my K's. The wheels all sit slightly further in by about 1-2mm - and the 2wd ones usually have to be spaced out as K's have really shallow hexes.

I'm just hoping it won't be super noisy metal diffs like Durango. looks like a pretty standard layout though. I wonder if the metal towers are actually needed - and if they will release a CF tower later.

That body's ultra ugly. Hope a few aftermarket show up soon. Still a toss up between this and the cat K1.

Isn't that a prerequisite of the buggy classes these days?? ugly cab forward body for downforce?

Dunno man the new cat K1 is pretty tempting.... I don't hate cab fwds all together but some are super ugly. This would look nicer if the rear was a bit lower and flatter (more swooping).
