CVDs for sand use?

[crazypoo#1]

I am going camping near a beach this summer and wanted to drive my rustler in the sand. My friend said that I will need to buy CVDs if I want to drive in the sand because the stock drive shafts will bind up. Is this true? If it is what CVDs do I want to buy? The only ones Ive seen are the MIP ones, and those are $36.

I have only seen the mip ones aswell but i would suggest out of alot of places not to run in sand escpescialy near water if you have a run away you cant run too fast on sand and you would lose your truck in a hurry. If you do decide to run in sand get a better airfilter you should probably buy another one because it will get dirty fast in the sand and get a very good fuel filter and lots of air filter oil. if you dont clean the air filter R.I.P engine
