I oreder from Hobby King and many of the members of my club order from Hobby King on a regualr basis. As a matter of fact, except for one LHS, Hobby King is the source that is recommended most at our field. I have bought a variety of items from them, including batteries, motors, a corona 2.4ghz conversion module, and various other items, all without issue. I know there have been some reports of problems, so I would say they are not perfect, or even good at customer service, but you can't beat the pricing. As far as the shipping goes, just realize unless you pay for better shipping, the average shipping time is 2-3 weeks and the tracking numbers are hit and miss as far as accuracy. If your concerned, why not try a small test order and see how it goes for you?
