Thanks kedal!
I also have bought several items which I broke during the last period, between other thing also an antenna for my radio :P I was pulling it out too fast on a race and it just came out the second last section. I also bought that ( .... what is it? Front hub carrier? on which the wheel axle is mounted ) what made my front wheel fell off on each jump an a race :P Still, I don't like my monster truck.... The Mad Rat is much simplier, much easyer to fix or to clean.
I am really thinking in buying a B-fast diff, before the stock becomes unusable.
Do you know guys, where could I find some off road track plans? If I would succeed to make a track here, i would like to make it interresting, not only turn-straight-turn-straight.......
