I just received my soft case from eBay today. fits like a champ. I was little worried it wasn't going to fit, but it was perfect.
Easy Carrying Backpack Shoulder Bag Case For YUNEEC Typhoon H H480 UAV Rc Drone
I like that it has a bunch of pockets for storing accessories.
I don't know how long it will last, but for only $30, it's a lot better than carrying the box around or paying $140 for Yuneec's overpriced, not available in any store yet bag.
The only thing, I would add are some velcro strips to keep the top case from slipping off when you unzip the bag. Oh and a Typhoon sticker to cover up the ugly red stipe.
