RE: hyper 7 rtr
Its a reasonable buggy, a bit on the heavy side, better on smooth tracks than it is on bumpy tracks.
Most people will say its a tough buggy, but its like most things, if you crash at speed something will break, but spares are cheap.
I have run a hyper 7 and my son still does he has a Hyper 7 with a pro uk chassis only thing he breaks are servos[>:] and he does hit things when not supervised (he's only 9 years old), I used to suffer from bent shock towers, broken shock shafts & C hubs, but you will expect this if you hit something.
The other thing I have noticed is the suspension does not work as well as other buggies, it seems that the arms are on the short side and I guess that's why its better on the smooth stuff. You get a lot of sag on the front and rear, so you have to go with a lot of spacers or thicker shock oil and heavy springs, which does not go with bumpy tracks. IMO
