It was a well known issue that we had a delay displaying HobbyKing stock status and backordered items.
Our programmers were able to fix this issue and now our numbers are updated every 24 hours automatically and every time the item is displayed on http://rcsearch.info/
We still can't guarantee 100% match but availability of each item is being check every time you open the page with the item. This will help you in making decision while shopping.
