I think it's a case of complying with the 'wording' possibly - but not the 'spirit' or intention of the rules. It simply ain't legal imho.
The sheer number of things you could get away with if micro servos were allowed all over the car would be insane. Servos have pots, the pots control movement in the suspension - you lock up a wheel and it could bind the suspension to some degree. So is 'that' active suspension? If it doesn't - then I'm sure you could design the car so it DID bind up - is that legal?
What about using just the pot to mechanically sense forces (with weights etc like some jules verrne type madness) and adjust things on the car.
Do ESC manufacturers start building in servo ports for 4-wheel braking? or servos on the car to prevent squat or dive?
If active suspension is suspension that moves and compensates for hard cornering - then I've already seen it done - purely mechanically.
Right, I'm gonna go put a servo on the back of my 410 and get some 4-wheel steering on the go - PROGRESS stylee
