So did the bad Y-harness come from Hobbico?
Some of the
newer HD Hobbico (now Tactic brand) extensions are some of the best on the market. I have tested just about every common brand and these test with the best of them. These use the same gold plated connector pins that Hitec uses on much of their stuff. Lots of junk extensions still available out there but there are more and more choices for good ones also. Just because a brand was bad a few years ago doesn't mean it still is today.
