There is a need to bash them for not selling and supporting their planes. The link you put up is bogus. Almost all of the "spare parts lists" are always out of stock. the only reason they put them up is so you will "think" they sell spare parts for these planes and buy them.
I have had crappy servos from a plane that I returned for over 6 months now and every time I call them on it, they say "oh, you still want them?" I don't think I will ever get them.
Just because a business sells a product for less than everyone else does not give them an excuse to say "well it is cheaper than everyone else so lets sell them crap, have no warranty or support". that is crappy business in my book. I am self employed and if I did that, I would be out of business.
Nitroplanes, hobbyking and Bannanna could be the best if they offered honest shipping and product support but they don't so they have an F rating with the bbb!
