I’m not sponsored by HobbyKing or any of their brands (Turnigy, TrackStar, Quanum, etc.), but I’ve found that they’ve been a boon for someone getting back into any radio control hobby on a budget.
Truth-be-told, I feel like more of a product tester than anything. That is sort of what sponsored drivers/pilots do anyway: they get access to the newest stuff for testing and feedback.
I just do testing and feedback on the stuff I buy, and since it’s so darn cheap I don’t really mind.
