Anyone have any thoughts or experience with this? http://www.infinity-hobby.com/main/product_info.php?products_id=10936 Wanting to convert my flat CS8 to a folding X8 and I found those above. They look pretty solid and affordable. Plus it looks like it will add some length to the booms as I'd use extra carbon tubing for the hub attachment area. I've looked at Flexacopter but they are expensive and I dont know about using plastic at such a critical point. I've seen the Darth versions as well but they also seem a little pricey. Anyone have experience with any other folding/detachable boom systems?
