RE: Ofna LX GT pro
The Hyper 7 is a racing buggy like the 9.5 -
No 2 spd upgrades for these. As for cheaper and so forth, sometimes when you get a lower end RC anything, some of the parts break easier. I put mine through a serious beating. My only problem is losing screws. Lock tite helps, but I still lose screws.
Hope that helps.
