rc corner weighting

[peteboo35]

im playing withthe idea of making corner gauges to set cars up any 1 with any ideas im thinking ov small bar ona hinge and sum small digi scales

I think you need to describe that better...?

Scales under each corner isn't accurate..

Why are scales under each wheel accurate? this is how we set up the full size F3 cars and is spot on.

Have to agree with above, corner scales are accurate, we also use them on bigger scale kart and comp car stuff.

Buy 4 mini scales

only if you use flat patcth and or if they are all level to each other then it will work for both f3 / any large car or RC cars.

To get it accurate and to be able to use the data from scales properly you need to get a consistant contact patch between scales and car... standard tyres are too soft and corrupt results

for full size cars with slicks we inflate tyres to 80psi all round to make them hard enough to give good readings and so its consistant.... plus they are kept as set up wheels/tyres and not used for anything else other than weighting or geometry set up.

if you had some set up wheels with solid rubber rings to grip scales then it works... i've tried to master it a few times but couldn't get it accurate enough to work like 1:1 scale

I've found that balancing wheels after fitting tyres on offroad cars is more beneficial and does make the car more consistant and jump flatter, it doesn't take much vibration to throw the handling out or the car to one side when its in air!

The easiest way to corner weight is 4 scales on a level surface. I use some inexpensive kitchen scales.

The results are not innacurate - but they can be a bit misleading. Because RC cars are built with larger "tolerances" (ahem) than full-size cars, you can end up with a different result every time you put the car on the scales. I don't get obsessive about the corner weights any more, but if I have one wheel that is, say 30gm more loaded than the others then I will give the car a good going over.

The scales are very useful for measuring weight distribution. Even though the corner weights can have quite a large tolerance, the left/right and front/rear sums are always spot on.
