The Hobao Hyper 7 is your friend.
It may be old but its sill current, and the fact its been around for a long time, just means there are UNTOLD upgrades and parts all over the place. It is the great nitro buggy bargain. I believe the old Sho was based on the original Hyper 7 design (I may be wrong, I remember it was based on one of the popular budget buggies), so it should look familiar.
