Honestly, I really think that the next advancement in R/C cars is still shock technology. But I don't think that advancement is to make the shocks bigger. I think that companies should be looking into piston technology and internal tuning, like a motocross shock.
R/C racers are constantly "tuning" their cars with stiffer or more flexible chassis designs, and that in the world of racing is ludicrous. You don't tune with an uncontrollable and inconsistent object, and certainly not the chassis. No real race car in the world is designed with a flexible chassis.
So why do we do it with R/C cars? Frankly, I feel it's because ALL of the shocks suck and don't have enough tuning, range and consistency in them to give the compliance you need.
Shin, Tebo and Kyosho should be spending time developing
better shocks, not bigger ones.
That said, we'll probably all be running useless big bore shocks this time next year.
