Here is my latest trick to making my excursion truck or any RC more versatile in water... I used to run standard foam inserts in my tires then they would always get damaged after a little water play... so when I got the new double tires i removed the inserts so i can go in water without any issues. with time the side walls got soft and I started to loose traction... well I was given great ideas by my local hobby shop about using BBs plastic or metal but I was worried I would start flinging them on faster runs so while driving home and passing a plumbers truck I saw my answer.... this video shows you how i am using pipe insulator for tire inserts. since they are water proof and hollowed this seems to be a great resolution to my "water-runs" problem. I hope this helps you please let me know your thoughts...
Just do it...they make replacement parts.VXL power
