I acquired 2 DHK cars (Wolf/Ray-r same car) both almost new and RTR for $150. I couldn't pass up the deal. I just got back into RC a few months ago so I am having to learn RC all over again. Any/All advise is appreciated. My question is what will it take to make both cars competitive on the track or are they just backyard track / bashers? What brushless motor/esc can the car handle with the stock gearbox? Any/All advice on upgrades is appreciated. And if the cars aren't "race quality" please let Me know.
