Ok, dont laugh...
My friend was showing me his very impressive RC Racing set-up and we got talking about vehicle dynamics.
He told me that some guys at his club had been testing Anti Pitch and squat bars on their RC cars. My understanding of that was either 1 bar connected to the front-rear suspension that worked just like an anti- roll bar except longitudally for pitch and squat (weight transfer) of course... OR maybe 2 diagonal bars going to each opposing corner of the RC car.
He asked if the WRC cars used them.. and why not?
He went on to tell me that braking distances are much improved, that the cars corner far flatter and faster and that with an active centre diff, a WRC car would be the perfect platform.
Although I'd never heard of them before other than the hydraulic systems in road cars.. I dismissed the idea as stupid and explained that longitudal weight transfer is a very important dynamic to have in rally cars as they need this high adjustability at the expense of outright grip.... as opposed to a circuit car where the track has been lapped many times, the lines and the braking points are very well known.
He argued that they could use a squeezable variable brake balance control lever (or handbrake) on the steering wheel.. and had good thought provoking answers for everthing I countered with.
Imo.. On imagining the dynamics and what would be required to make it work its simply too complicated, with questions on how the car would react on jumps, rough ground and a totally unnatural driving style would be required, the very opposite direction rally should be headed imo... but I told him Id ask others opinions on here.. :D
So?
