Blackzon Slyder ST 1/16: stiffer springs

[element]

I'm new to RC cars, I have a Blackzon Slyder ST 1/16 4WD (link below). I've modified it for my purposes, which added weight near the front. The front suspension dropped. I compensated by squishing the front springs almost all the way down the pre-load. I want to use stiffer front springs. But, being new, I don't know what springs are included by default: there's no "pound" spec in the manual. What pound / size springs should I search for, if I want something stiffer than what's in the box? Thanks.

A fine quality rc like that shame on the maker.. there's a few things you could do go to your local rc shop ask them if the have a spring tester...measure lenght. inside dia.and outside dia.and try to find something online that is color coded...

You can figure out the spring rate with a kitchen scale and a ruler or caliper.

Care to enlighten us as to exactly how? That might come in handy some day

You compress the spring 1" and take the reading. You'd have to tare the scale first to account for the weight of the spring. It's actually best to compress the spring 1", then tare it, then compress another inch though I believe. For shorter springs You'd just have to calculate the value per the amount you are compressing the spring. I looked into this as a potential project back when we built the Servo Punisher, but forgot all about it.

Thanks! I need to finish putting my servo punshier together. Its still half in pieces on my bench O __ o

1” is a long way to compress but that’s the idea anyway: you know the distance you compress and take a reading of the weight. I make several small changes to the level of compression to get more dots indicating a slope.

Another way is to take a known weight and measure how far it compresses the spring. Ideally, again, you may do better if you have 2–3 weights and compare how far each of them compresses the spring.
