The physics of full size cars do not relate entirely to model versions...

a 1/10th buggy scaled up by 10 would have 22" wheels, 12cm bore shocks that were over a metre long, weigh around 16kg and be capable of 500 mph+

i understand entirely where you are coming from, have done a motorsport engineering degree so can relate to all principals but facts are that adding weight in certain conditions improves consistancy.... when i came back to the hobby it was a surprise to see brass being used when years ago we were making everything lighter for speed.

back in XX XXX days we were also very limited with run time and punch from batteries, modern technology means that power and runtime are no longer any issue, so running a heavier car is not a is advantage i it suits driving style.

I've found that running weight and tapered pistons makes the car a lot more consistant and smoother on bumpy tracks... if the car/wheel is in the air from little bumps then there is no power going to ground and technically you are not 100% in control of vehicle.

we use spike tyres, push the spikes into the ground and you have more grip, trying to use suspension to do this will also push car up into air.

circuit car principals do not apply to off-road vehicles either... Colin Chapman never designed a championship winning rally car?!
