I had yama buggy for a year and to be honest if you go bashing you notice it really can't take it but all brands do break but it's all down to the quality and I noticed when I Hooked up with a bashing group there cars eg HPI, KM and LOSI were going on and on and the build quality of them was massive.
All I was greatful of that it gave a learning curve in the 1/5 scale petrol world. The yama buggy was fun but now I'm selling all the parts on eBay as I've purchased a KM baja which is great.
Mate if budget allows save a little bit more and get a KM, obviously this is all done to matters of opinion
Hope this helps ????
