Well so far so good, the truck is well built and strong, very fast. But I have only ran it inside so for. I am going to a local park that has an offroad bike track, to run it through its paces. As for battery life it comes with same Mini-T 7.2V 1100mAh battery and I was able to run for about 20 minutes, actually a little over 50 minutes ( I bought another battery too.) So today will be the real test. But I have found anything really bad on this truck excpet the battery holder set up in the truck. It is really tight and difficult to connect the battery wires, and the atenna is a little to short for the antenna tube. Thats really about it. And can't find any hop-ups yets, but they are coming, I know they are.
