X-6 rear outer hinge pins
 

It says in the manual that dispite the fact the hinge pins pertrude from the wishbone the screws will hold them in fine. Ive ran the car twice in practice and the hingepin slides out as soon as ive landed a jump losing the wheelbase shims. Has anybody else encountered this problem?

is that the wheel hub one or the one going into the chassis? ive found this a lil wierd with mine

I will agree this is an annoying point, but if you've got the little screws in there, how can they fall out? Do the screws fall out too?

Personally I ground the pins down a little with a dremel, just using a normal sanding drum, just took a minute, holding them it a set of mole grips.

Chris,
are you being an animal and dogging up the screws so they don't go in straight? Honestly, if you do it as it so the screws are straight, don't need to be tight, just touching on the pertruding pin and alls well.

If this is the case, try doing like Dan says with dremeling it, then also put a washer on the screw and it'll be bombproof.

Mines built with pertruding hinge pins and screws just touching, no washer.

as Chris said mine protrude slightly, but just have the screws touching them. had no probs but I'm planning on grinding them down a tough so more screw is inside the wishbones,remember there only tiny screws be gentle with them

i have some shorter hinge pins in altogether. they are slightly longer thn the front outer pins although the ones from the front will still fit. im not fully sure what i got them off :eh?:

I use the racers edge hubs which have a grub screw to hold the outer hingepin. BUT i also ground the pin down so the screw in the wishbone held it in aswell
