If I wanted to buy 4 scales to scale out an 1/8th scale e buggy, what kind of scales would I need? Like, what kind of capacity? I've found some 1200 gram (2lbs 10oz)digital jewelry scales for pretty cheap.

ok ive seen this before somewhere else but ill re-explain. scaling an offroad car doesnt work unless its oval. your setup for offroad should be done dynamically, meaning drive it and adjust for the track. scales will just lead you down a garden path to nowhere. im not trying to be rude, and im smiling while typing this..i just dont want you to waste money on scales. onroad cars are a way different beast. but also, if you wanna try them you will need something a little bigger scales, something around 3-4 lbs each to be accurate. cheers!!

I use 1 scale and three pieces of wood planed to the proper height.

I diasgree with everything this user wrote.

I use four 1000 gram scales (I found on Amazon for under $5 a piece), and they work on my sedan, on my asphalt oval car, and on my short course trucks offroad.

I've never weighed an ebuggy, so if you think you'll get a wheel position that is close to 1000 grams, 1200 or 1500 is fine. Make sure you have a way to level and check the setup board for level every time you use it, if you don't, the weights will be off.

I used to do this on my oval car and just weigh the left rear tire to set the crossweight, but on a off road or road course car it's too cumbersome to use just one. And if you only have one, how do you know it's accurate? Plus the scales are insanely cheap now compared to 15 years ago.

Usually, I have my scales set up and check wheel weights before and after every run to make sure they haven't changed, particularly if I got in a big crash. I write them down at the beginning of the race day, and if the weights have changed, something is bent or broken. Makes it easier to keep an eye on things if you're running multiple classes.
