Hello again, HardBash. I have a similar problem here in the Rocky Mountains of the United States. That's why I've wound up joining you with the purchase of an Arrma Typhon 3S. Another vehicle that I've had a lot of success with in terms of fighting off the effects of little pebbles is my Traxxas UDR. However, I vacation from time-to-time in various places in Scandinavia so I know how much more expensive things can be there compared to the USA. I can only imagine that a Traxxas UDR would be even more expensive to purchase there and maintain. Another way of dealing with it is going the 2WD, rear motor, covered spur route like a Traxxas Slash. Yes it's a little more important to select the right tires, but it can still be a fun time. Heck, maybe even more fun when you through in the challenge!
