I very much dont like this ^^



Something that strikes me is the reference to full size cars, but you dont often see full size vehicles jumping 10 times their own height regularly on a race, the useable stroke on a full size car will be very little methinks compared to an R/C car, i would imagine the forces are exponential too ? Will the hi/lo work on such an extreme action?

Bump stops V's pack
because pack is effective for the most part of the piston stroke its effectiveness is hard to beat for a smack down landing.
It is something i have thought quite a lot about and have come up with various ideas like broaching the side walls inside the shock body to give variable damping but am not sure about the manufacturability of this.

your mention of not seeing full size cars doing massive jumps is a good point.
at tenth scale though, impacts from massive jumps are not nearly as destructive.

you can see quite a meaty bump stop nugget towards the end of this vid
these things take quite a bashing.

Some folks mention the difficulty of setting up more complex shocks.
sure, it would make things more complex.
but its child's play compared to most normal motor sport.

personally i like all the technical challenges in r/c racing and would hate to see something dummed dowm because it might be difficult to understand.
