I have 3 SCX rally cars, Fiat 131, an Escort Mk2 and a Fiat 124

The 131 has almost no play in the front axle (but still spins freely), the Escort has just less than 1mm and the 124 has just over 2mm.

The 124 looks odd as if pushed side to side the wheels protrude outside of the body. Now I can add spacers or cut the axle shorter so the car looks better or is the 2mm 'slop' an advantage?

Regards,

Alan

I don't know what the "accepted wisdom" is, but FWIW I take as much play as I can out of all my axles - leaving just enough to allow the wheels to spin freely.

Works for me!

The "accepted wisdom" is that there is no universal answer
Try adjusting it and see if it makes those cars better or worse (or quite probably makes no noticeable differance).

My wisdom, definetly not the generally accepted version though, is as follows:
- Wheels must spin freely throughout all the potental body rock movement
- Sideways slop/play is an absolute no no
- Max the possible width
- Front wheels/tyres must be round
- The tyres should just touch the track with no or min vertical play

Thank you everyone for your replies.

My thinking was to take the excess play out (either by adding spacers or shortening the axle), I just found it odd that 3 cars from the same manufacturer were so different.

Off to find some spacers or the dremel!

Regards,

Alan

Funny, I was driving my car the other week around my track, after doing a dozen odd laps, I looked down at my car and saw that I had forgot to put my front axle and wheels/tyres on full stop!, lol. I didn't notice the difference in the car at all, I was gob smacked, was dead funny though.

With cars set up so the front wheels don't touch the ground, it rarely makes much differance if you leave them off all together.
Some types of car work best with the front wheels off the track, other's work best with the front wheels having at least some contact with the track.

Hi, that's true, I just thought it was funny how I didn't notice for so long, must have been the poor light in the room or something, I clearly wasn't paying attention.

I suspect that you were running the car with magnets and on plastic track?

Hi, yep I was. It did make me think though - that I spend all this money on fancy front Alloy wheels, zero grip tyres, hollow axles, fancy bushings, and yet I don't even need too. But my mind says I have too!, I don't have many cars, but the ones I have I like to have good racing/performance parts on them, even if the gain is not noticeable on my Scalextric track.

Alan you can use Chuppa Chup/Lollipop sticks cut to size with a sharp knife and slit so they go over axles without the need to remove the wheels if they are glued/stuck in place like the SCX/Scaley ones are. Another great and cheap tip that I have read on the forum and works a treat. I take out the slop on all my cars, front and rear with this highly technical approach.
