There's a picture of the 4wd body off from the reedy which gives away a clue

Doesn't look like there is anything at the toy fair, only trf stuff is 44mm driveshafts which I think are trf417 size aren't they?

You know if you have it right, because if so it is only tight for about half a turn of the nut then it loosens again once the hex pops over the fitment!

it is there problem with the white tamiya wheels or with the tamiya hex? I hade try already your way of fiting the wheels but the problem is that i have now two pieces hex, it is broken on half

dont thinkso , you may have over tightened the nut like i did and broke it as this is what i have done.

[df-03]

yes, i come whit that idea before you post it so i do not blame you for mine mistake if you think so , mine question is it is there problem with white tamiya wheels only, or black and other tamiya wheels fits without problems or i have to use some other brand hexes?

Hit the front wheel hard enough and it can crack the hex in half, but you don't notice until you take the wheel off and you have 2 bits have had it twice on my trf511....its just if you catch them at the wrong angle because they are very hard. If it broke when you have been fitting the front wheel before you run the car then it has not been aligned up right with the hex in the wheel. Never had a one break when fitting the white wheels.....

I find one of the yellow ones slightly easier but not much. I have only broken hexes where the wheel had been fitted wrong either that time or before. Unless the inner hex surface on the wheel is completely flat it snaps the hex, check for material in that hex. It's caught me out once or twice!

[fastinfastout]

the tamiya rims are a very very tight fit.

I ran my hexs through some emery paper on all 6 sides until they slide on and off easily. Otherwise you might break another hex from putting too much pressure getting the wheel off(happened twice already)

[df-03]

yes, i think that i would in future grind the hexes with some sandpaper to make them fit easy cause spareparts are hard to geth

[DaveG28]

On the steering, I fitted the new angled steering at the weekend, and am in 2 minds on it:

1. It did feel more linear, less twitchy and just felt a bit more "right" to drive.

2. However....it still leaves an issue on steering lock, and it doesn't feel like spacing the inner studs forward fixes this like on the std steering, the geometry makes it less effective (or seems to).

So...I am either looking for ways to increase lock on tight tracks still, or will need to swap between the std and angled versions for different conditions.

Has anyone else tried it??
