RE: Vent about rc cars you regret buying..
Nitro Evader....took a lot of ball differential rebuilds before I figured out a way to keep it from self-destructing.
(I didn't buy it....I helped my son's friend with it, but from what I've seen, I would have had regrets for a while)
Also, not really a regret, but the Baja 5B isn't much fun (for me). After a few mods, it became too reliable, too easy to run, too "perfect", so the challenge is gone. I'd like HPI to put out a smaller version with a fussy nitro engine I can play with.
