when crawling.. why would people use droop suspension ?
I cant reason it out.. Please advise.

It gives you a very low center of gravity at the cost of of some ground clearance. It really helps steep climbs because the car does not want to unload the front end and cause it to flip over backwards.

What Ted said, plus there can be several more reasons. The first droop setup was on my Jeep bodied rig, because I was going for a sort of scale look out of it. Droop allows the tire to drop, instead of lifting, when the suspension travels. In order to clear the tires when it was fully flexed I would have had to mount the body so high it would have just looked rediculous. With droop i could mount it low, to sit more like a real Jeep does, because the tire will drop instead of lifting up into the body.

People running droop setups keep the chassis undercarrage
as smooth as possible. Low CG is a top priority and your chassis
must not Hang up on things. Think of it like this,,If you were climbing
a rock face or mountain you would Hug the rocks.

I use a droop setup on my 2.2 scale blazer because it looks way too tall the other way. Plus I'm happy with it's performance.

I run "mid sprung" my self for the same reasons as stated above. I prefer mid for 2 reasons.
1) a little more ground clearance at ride height
2) I wanted some up travel as well
I wheel 1:1's as well, and on my 1:1 trucks I have around 8" of compression travel, and around 14" of droop. I know that with the weight placement differences between RC and 1:1 there is not a lot similarities in chassis set up, but I take the compression travel for granted. I found with out it on my RC it was hurting my performance (mental thing) so when I went mid sprung it was a lot peter performance for my driving style.

Droop, Sprung, or Partial Droop all have the same articulation capability to start with. They each have advantages on certain types of terrain and vehicle types.

Droop is happy at any ride height but most people keep it at about 2.5 inches. This keeps the weight down low. Belly clearance isnt as much of an issue on droop since the suspension moves down away from the chassis instead of up to it in a sprung setup. With proper setup the axles will 'droop' down when the belly gets hung up, this allows for much better breakover clearance on obstacles.

The other benifit of droop is especially for shafty rigs and fighting torque twist. Instead of having to crank down one shock to keep the fronts planted you can use a minor increase in shock oil weight to acomplish the same thing and have very little impact on the rest of your suspension when driving.
