Nothing is more accurate than than the scales. But I believe DS has stated that the suspensions, shocks, anti-roll bars will affect somewhat the readings.

I do use the hudy pins and they are a great way to see where you need to add weight.

I have 4 scales, but I usually use 2 to balance the car.

The hudy pins are great if you want close and quick, but they have a large sticking point (30-50g per scale if you remeasure what you thought was center)

You need to balance the chassis, and also the suspension. The chassis is balanced without roll bars and equal shocks (length and tension) plus setup wheels.

The suspension is easier to do with something like the old MIP or hudy tweak board to adjust the preload on the sway bars without shocks, and then preload on the shocks.

Brian, can you explain how you adjust the swaybar preload and balance without shocks on tweak board please?

can you tweak the car manually without the tweak station?

can you adjust tweak using scales? eg, place 2 wheels up on scales and the other end on a board? or do you need a station

im going to buy 4 cheap 1kg scales.

How do you balance the weight of the car left to right? Do you add weight on the side that weighs less? What kind of weights do you use?

Sorry for all the questions - I'm still learning.

I was just using the Hudy balance pins tonight and noticed it was quick but not accurate. Anyone have suggestions on what scales to get? There are a ton on eBay, but a suggestion would help a lot.

I overlooked that, thanks!

What kind of weights do you guys recommend using for balancing?

Thanks for the PDF link. Now I can just buy 2 scales instead of 4.

I studied the instruction.
Is this with or without anti-roll-bars on?
Is this with rubber tyres or better with metal setup wheels?

Without anti roll bars and preferably with a set of setup wheels.

Also make sure everything is leveled, especially the two scales.

This is what is posted in the electric thread:

For balancing out the car by using weights I wouldn't suggest putting the car on four scales but one axle on the scales and one on a Hudy pin.
This eliminates the variables like chassis straightness which can cause a false reading.
If you want to do it perfectly you should also replace the shocks with a set of turnbuckles.
First you will dial in the left/right balance on both axles and then the front/rear balance.
When you set it up like this and build your shocks properly you don't have to balance out the car by changing the spring preload. This gives you a very good handling car.

What max weight should one scale have?
I see several kinds.
Up to 200 grams, up to 500 grams, up to 1.000 grams.
I don't know how many grams pressure there is on every wheel of a 1:10 touringcar of about 1.400 grams.
