"Floating Servo" holder - why would I want it?
Can someone explain to me why would I want a "floating servo" holder? For many, many years, we've always wanted for the steering servo to be fully locked down to the chassis. Now, it appears that we want it to "float"?
Can someone explain why would I want this now?

Fully locking down the servo in the traditional way has a small influence on the flex of the car on the side of the servo. In effect, your putting a brace across the chassis, limiting flex.
'Floating' mounts do away with the bracing effect, by having a central mounting location, allowing the chassis under the servo to flex freely, theoretically evening up the flex.

With a traditional side fixed servo and the current flex levels in the cars, an unwanted steering action is created.
This is because the bulkheads and steering pulleys run along the centre line of the chassis bracing it, and flex along the centre is limited, but the servo mounted on the edge moving with flex can move more relative to this centre line. The result is just by flexing the car you get a steering effect.
With a floating servo mount you'll notice they all pick up their mounting point along the centre line of the chassis and so flex and move about at the same rate as the bulkheads and steering pulleys. The end result is you can flex the chassis about all you want and the servo and steering pulleys just all move together and you get no unwanted steering affect.
Not bracing the chassis on one corner evening out flex and preventing tweak is an added bonus of doing this.

what abou tthe lipo side? We're gonna have floating lipos too?

Lipo's are fixed fairly loosely in comparison to the servo mount, so the effect on flex is very marginal...enough to be able to rule it out as the chassis can freely flex underneath the lipo as there is no positive locking between the battery and the chassis itself. the same story goes for the receiver and speedy, the double sided tape flexes with the chassis negating the effect.

This would be the next servo mount all TC cars will follow. It simply makes so much sense to have it that way!
