I wanted to take a moment to commment on the customer support that Horizon Hobby has on this product. I bought one of the early release Blades some months ago. It was ok but developed some problems over time. Long story short... after two returns to Horizon Hobby, they replaced the WHOLE THING with a brand new one. They even replaced my aerobatics kit too. Not a single cost to me what so ever. I am amazed with their level of customer commitment. I will continue to buy Horizon Hobby products!!! Thanks guys!
