I've got a Turnigy 9X with the FrSky module and have ordered a few times from Hobby King. I finally noticed Aloft Hobbies and figured I'd order from a US source to see how much more quickly I could get the order.
I placed the order last Friday - a telemetry receiver and data display. The order was placed before I noticed I forgot the voltage sensor, so I called and talked to them in person (IN PERSON!) and was told to just order it right away and set it up as a pick-up order. They'd combine the two and ship it together.
The order shipped out that day and arrived two days later (California to Wisconsin) for cheap USPS shipping. The voltage sensor wasn't there. Not a huge deal, I know they're busy getting their new radios and gear shipped so I called and explained the problem. Again I was able to talk to an actual human who speaks English as his first language! He apologized and said they'd ship it that day at no charge for shipping or if I was ordering more they'd just add it to the new order. I didn't need anything right away so I had them ship it. That piece arrived today, so the order is complete and received in less time than it'd take for Hobby King to ship the typical order.
I'll be ordering everything I can from these guys now - the price is basically the same as ordering from China, but that kind of customer service needs to be rewarded with more business!
