I used to Race RC trucks, gass Baja, stadium and prerunner,
The trucks were 18 to 24" wheel bases, and some ran solid axels and some ran IFS and solid rear, i Liked the four wheel wishbone indipendant suspention, and used to build my own custom A-Arms and shock towers, better controll and traction,
NOW for thoes that dont know you ahve the same things to think about in RC racing that you have in full size, power to weight, traction chasis suspension, and these are not the $30 rc cars you buy at radio shack, these are fourwheel drive, geared cars taht range from a $300 STARTER chasis all the way to champion trucks with titanium chasis runing 1k+ for the chasis alone without the suspension., but in gass RC your motor and fuel weigh 2times more then the rest of the truck constructed
I liked the FWIS because of the clearance, we ran the diferintials up inside the chasis, and ran longer Arms , with controll rods, and a dogbone drive axel, "similar to a CV axel" down to the wheel, and then a hub and wheel, disk breaks, mounted on the drive axels instead of the wheels, thoes things are spendy and to lose a wheel going 40 -50 REAL MPH not scale mph. the disks last longer inside the chasis.
And we came up with a IS that let the RC at 3IN ground cleariance put the fron wheel 10IN off the ground while haveing the other 3 wheels on the ground and accomplish
6IN of travel on each tire , while keeping the chasis of the truck almost level.
ew called it a floating indipendant suspension, i have been workin on blueprints for a few years for aplication to Off road Vehicles, was set back when the RC trucks burned in a garage fire, and all the sketches i hade and working model, but its diffrent on a bigger vehicle, lot of strength issues to figure out and a LOT of math i would go into more detail, but it will be a while befor i have the resources to build and test a model, but i have been looking at the zuk as a good place to start. we could also adjust hight with servos, from 1IN ground clearince to 3 in and mantain all flex throught the hight adjustments.
Once i get a perlimenary set of plans that work in auto cad, I will seek help from some of the skilled patrons I know and Read about here
any way i think IS is MUCH better then solid axel.
