I was going through some sites trying to get some ideas for a truck im gonna build just for glamis.I came accross this slash.what you think?The 2nd set of pics is a baja 5b and the last is a homemade rail based of a associated t4 truck.
I think the biggest thing in running an RC car on the dirt is size when you get into real environments. I have had several 1/10th scale buggies\ trucks out in the desert and for the most part all you get is wheel spin. Its kind of like running in a wash the entire time. If I were you I would just go buy a baja 5B or 5T
Look those up on youtube as there are plenty of videos.
