That's not droop. That's downtravel. Similar but different.

To properly measude your droop will depend on the manufacturer but you'r trrying to limit the travel of the arms to control weight shift. Most manufacterer's will measure droop using a stock set of rims. Rest the car on the rims with the shocks undone. Then measure either the low point or the middle of the outer hinge pin, however it says in the set up sheet. It really doesn't matter as long as you keep in consistant in how you do it.


You can do this with the shocks but it will generally put a little more stress on the shocks, increasing you chance of breaking a shaft or stipping the ball end on the shaft because of the constant pounding. Besides, that's why the droop screws push through the arms.

The first way is fine. All you are looking for is a consistent reference point from which to make adjustments. Just be careful though if you switch shock locations. Your measurement will change but your droop would not have (unless for some strange reason you have so much downtravel your droop screws arent touching the chassis and your shocks are topping out)

It will work but it's not the right way to set droop on any car that has the proper means to do it properly. Those little set screws in the arms called "DROOP SCREWS" are there for a reason. You will get a better overall result doing it properly.

Droop is with the weight off the wheels. Typically it's easier to set droop with no wheels as most measuring points are at the hub area.

Ride height is with everything on the car and fuel in it, how it would stif at the start of a race on the straight.

You use the droop screws. You just measure the length of your shock as a reference point. As you take droop out, the installed length of the shock gets shorter, as you put more droop in, the installed length gets longer.

The way Losi describes droop measurement is measuring the distance between the upper and lower shock screws. This method works as long as you never use any other shock location than the one spelled out in the setup sheet you're using.

Does anyone make an 1/8th scale sized droop gauge? That would be the correct way to measure droop, which would give you freedom to move the shock location around.

I suppose the other way to do it is to set your droop using the Losi method in the known shock location, then move the shocks without touching the droop screws, then measure the distance between the shock screws in the new location and make note of that. Pain in the butt, though!

Hudy is coming out with one. Look on their site. look at how they measure droop on TC. It's the same on a 1/8 scale, just bigger. The great thing about the droop screws is you don't have to take your shocks apart and add limiters most of the time, you can adjust your droop.
