Outer Limits 4x4 Board

Just wondering what RTI figure mogrover has achieved? I don't expect it to be up there with the hydraulics and hence, it will be interesting to see how useless the RTI is, as I'm assuming that (from the other thread) mogrover is at least as capable as the other hydraulically suspended rigs, yet achieves only a fraction of their RTI figure.

Its never realy been ramped. We have a 20* ramp at work but i think we only drove it up that once to make sure the front pinion didnt hit the sump on full compression.

Personaly i dont beleive RTI means anything when it comes to capabilities.

Here here!
I agree with Ruff on that one,

I third the motion!

A well designed and balanced rig will outdrive a flexy rig any day of the weeK!

It does flex fairly well. Nothing major but probably better than most. Its got 14in travel shocks (all mounted fairly vertical) on each corner and it can max them all out when it articulates.

The thing with flex, I believe, is that you should try to have as little as you can get away with and not as much as you can get. I see alot of rigs that just have so much flex just for the sake of it and they suffer badly from it in terms of ride height or stability.

The beauty of the hydraulic systems that Antunac and Dobbin run it that when they dont touch the hydraulics they dont have massive amounts of flex and so they dont suffer the same problems that lots of other rigs have that try to match them on the ramp. I think that Dobbin also has 14in vertical travel at each corner and I now believe that Antunac is bringing his back to only 10in vertical travel at each corner without the hydraulics. So both these rigs have limited controlled flex without the hydraulics.

Ill see if I can measure what it get on the ramp tomorrow but I dont think it will get much more than 1000 on a 20 degree.

Ramp QUEEN!!!!

I agree, yes you need SOME flex (enoungh to keep the RIG stable) but to much and it will just be to SLOPPY, also i havn't yet seen a REALLY FLEXY rig that has been able to get the POWER to the groung SMOOTHLY.

My thoughts exactly.

Measured it and it gets 1050 on a 20 degree going forwards so it is actually less than I imagined. (I think this works out to 720 on the 30 degree they use in tuff truck)

Sam

Wow that isn't a lot is it. Hmmm goes to show huh....

yeah sorta agree with u sam and troy, my truck has nice front end flex on the trail but on the ramp it does shit forwards or backwards and i think that the flex i have is good in the aspect that it doesnt feel floppy 2 drive like it used to

I think people put to much emphsasis on there RTI .Most rigs with huge RTI are unstable I think a good balance between front and rear is way more important there aren't many ramps oput in the bush or on that side slope.
SAM

never seen a ramp in the bush, so why bother ramping it before ya head out ?

RTI = waste of time .... balance,clearence,grip,& control wins every time !

i find the ramp usefull to check on bind with bushes, shocks, uni's and the like. even to check tyres hitting guards, arms and flares. the ramp is more stable then using a highlift and easier then digging holes. i know it is only a static measurement and does not allow for any inertia (compression or extension)
for me it is a tool and not the gauge.
