The hyper 7 you link is not a true truggy, it's a buggy and the guys have put wheel extension and truggy wheel.
Don't touch this, it's alot of trouble. The geometrie of the suspension on a buggy don't allow you to run truggy tire and wheel, because the shock will bottom out before the frame touch the ground,= lot of shock and tower snaping. I know i've did exactly the dsame thing with an Ofna ultra MBX.
If you want a truggy, get a true truggy

And for the Turmoil, i don't know anything about this buggy, but as others guys say, for the price, it's hard to beat, and normally, Horizon give an exellent support.
