Tried the YZ-2 on a mixture of astro and grass today, quite bumpy and was very greasy as the track got damp, tried it in kit format and then tried it with shocks on the rear. It was a bit edgy to drive but not changing anything just yet as I've just ordered some Dboots to try on it.
Heres a video excuse the shoddy driving haven't been racing outdoors for 2 years!!!
It should work the video is on my Facebook page.
