articulation ramps

o.k., i understand the basics behind the ramp, but is there a specific angle that all ramps are set at? and how do you measure the articulation, or whatever else you're looking for (droop,flex,etc.)

Re: articulation ramps

As I remember, there are three different angle ramps are set at.23,28,and 30 degrees are the most common(I think). Someone can score a 1000+RTI on a 23 degree, but a much lower score on a 30 degree. When someone tells you what they scored, ask them what degree the ramp was set at.

Re: articulation ramps

The ones I have been on and have herd of are 20*,23*,30*
To measure wheel base/distance traveled X 1000= RTI

Re: articulation ramps

That math looks funny...

If you travel half your wheel-base up the ramp, you would get a 2000! I'm guessing it SHOULD be:

Distance traveled / wheelbase * 1000

So traveling half your wheelbase would give you a 500. So, to get over a 1000, do you run JUST the front wheel up the ramp, and keep your back wheel OFF the ramp?

Re: articulation ramps

Here's a page I set up to describe what's up with the ramps...

Re: articulation ramps

I dunno, Scott - I can get to your web page, but if I click on the RTI link, it craps out - same if I just click on it from your post.

Re: articulation ramps

Odd, I've hit it twice now and it's ok. Basically, it says (with pictures):
Simplified: Inches Traveled divided by Wheelbase, multiply by 1000, equals RTI
Original ramps were 20 degrees, then went up to 23, finally up to 30 degrees for the highly modified rigs.
