I believe it's generally the angle between the front axle and the rear at full stretch. My comp buggy has 25* freely, but it can get ~40* in a bind.

yeah that is basicly what i mean too, my front axle is at bout 35/40 degree's up off the ground when my rear axle starts to lift....cut that in half and that's what my articulation is at bout 17 to 20 degree's then ...............bob

I always say Down travel is traction, but I deal with 1:1's a lot...

Articulation isn't everything!

I had been obsessed with maximizing my articulation, thinking more is better. I've done some mods, but there is always that obstacle that is just a little too high. but I have noticed that my high speed control ability has gone down some as i look for that extra degree or two.

thanks for the write up.

I think they need to back the pre-load off on those springs.

this will realy help the newbs! all they want is more more more flex (i know i was the same when i started!) but it ends up just hurting them!

Exactly. More articulation looks cool on a shelf, but isn't the way to go in competition crawling.

I think they like to jump those any chance they get. I haven't seen one perform, but I sure wish I had the money and time to do something like that to my Tracker.

That brings up an interesting point. Free vs Bound.
On a bench if I lift thge front tire I will get about 1 tire height of flex.
If I really stretch it all out and flex it hard I will get a bit more, tire compression is one factor. This simulates a real bind.

Not sure if free vs bound articulation is a valid topic but I do know there is a difference for me.

I think it would be safe limiting to 75* bound and 30* free. I can get it my MOA to make almost 90*, but it would be a helluva bind on-course to put that much force on it while not progressing.

I was ready to start tearing apart my shocks to get more flex out of them, but I think I'll leave them alone after reading how you like to get as much flex as the size of a 2.2 tire, that's about where I'm at now.

That is a good starting point. MOA vehicles can get away with a little more travel, than a shaft driven truck. But, in general I have found that less is better to a certain degree.

When I first finished my super build it had over 8" of articulation ,
but after quite a few mods and adjustments to height and weight I limited my shocks and moved them around a couple times and now with a much more stable platform I have about 6 1/2" articulation
It's working .

+1.

Having ~= to one tire diameter flex is a great start. You can mess with shock oil viscosity to help "float" a tire over an obstacle. It may also mean you have to "wait" for the chassis to settle to get better tire contact at times.

Thus the "degree angle" for most rigs is similar, the amount a flexed tire will lift is dependent on tire OD.
