Yeah you wont get many people saying anything but good things about a Hyper.
True the ground clearance isnt that of a MT but its still enough to make it decent at offroad. The Stadium trucks are good too so i wouldnt advise against one. The Hyper ST looks cool but i havnt had any experience of it.
Hyper 7, there cheap, well built, good runners, very popular, and easy to get parts for.
Main point being the cost, 180 squid cant be better spent. But if your set on getting a stadium, its not a bad choice, others should be able to advise on what model would be the best.
