Durangos Center of Gravity

[lastplace]

Hi guys need some help with a little project
just wondering if any one out there knows roughly what the DX410 and 210 Center of Gravity is with referance to the cars Chassis Bottom.

I know it will change with ride height, that's way i need a referance datum from the Chassis bottom

i'm trying to do a Roll Center Spreed sheet, done all of the plotting and getting figures that look right but without knowing The CoG got no idea if it is increasing or decreasing, I suspect Durnago must know from the design side.
but has anyone else tried to worked it out.

I Know this is sad but i don't have a life :p and i can not get my head around roll centers, camber links and all of the other stuff
so help a poor demented fool who plays with toy Cars :thumbsup:

Its in imperial, fairly easy to covert it all to SI units though.

Hi Chris
I must be missing somthing here, whats in Imperial. the position of Center of Gravity is a position of a point that the cars is in Ballance around.as i understand it it's the total values of all of the mass of the car

if where talking imperial Inch than multiply by 25.4mm fine but i was asking about the position from either the ground or from the chassis ?
the Cars CoG will have a physical position on The 3 axis X, Y & Z ( Z being the height)

its position will be differant depending on weight of battery its placement in the chassis, The motor weight even the size of pinion could have an effect as it would move the motor away or closer to the cars center line.

what i was asking is a rough idea , Ive been guessing around the 15 to 20 mm above the bottom of the Chassis , when the car was first designed they must have had an idea of want they required to make the chassis work with the cars geometry

A touring cars will be close to the ground but the off road car will be a lot higher so the position of the RC point will have a lot different effect.

Sorry Chris
I was missing something the link at the top:thumbsup:
had a look and will see about giving it a try once i make up some plate's to lock off the suspension

many thanks but was hopping i could get a respose from one of the Durango boys save all the hard work

cheers

Roll center calculator work so far, angles look right but some fugging of the data but gives some idea of what happens when you change camber links and use different hole centers
