i have run ofna, ae and mugen and the mugen has been the best to drive by far, the ae was fast but not as nice to drive as it was always a bit skitty. the mugen are always planted and the quality is one of the best on the market. i must say but that i have raced against hbt and they hold their own on the track speed wise but can not comment on reliablity, if it was me spend a bit more and get the better quality of the mugen and the building of the kits is the way to go as you learn the truck for when something does go wrong you know exactly how to fix it ...my 2 cents
