Don't Bash Streched Wheely King
I just learnt this lesson the bad way, so I might as well share it.
I streched my WK to 12.1 in, and bashed on rocks with stock motor and gears (which means mid speed). All 4 shocks are bent, with one particularly bad (stuck in the housing).
The reason being after streching it, the shocks are slanted. Upon impact (crashing into things, horizontal wise), the shock will take some of it. Before streching, the shocks are vertical, and horizontal impact are absorbed by lower links.
I will solve it by streching the shock mount too, so the shocks will be vertical or near vertical
