I have pretty much the same postive experience as the other guys have reported above, BUT I have one suggestion, as follows:

On a backordered item that you don't need right now, place a separate order for that one item. I've done this and while it's a tad more expensive due to shipping you get it as soon as it comes into stock. Since it's the only item in the order, it does not hold anything else up. I do this with specific items I like and that are more for stock than a specific plane, as it could be a while before it ships.

I have five of the three wire power switches on backorder like this. They are great switches and less than 25% of hobby store prices, so the $2.99 postage for 5 of them is still very inexpensive and I don't have to keep checking the site to see if they are in, then place the order. I did this with the Orange HK brand Spektrum compatable receivers too. These do not stay in stock more than a day or so, but my order was queued up and shipped quickly. I limit this to reasonably priced orders, as you pay when you order, not when they ship, so HK is hanging on to your money.

Remember, you shouldn't order anything you need right now from HK. I've had orders arrive in a week and also in four weeks.
