I've been into high end rc cars for years and have many but I recently bought a syma x5c and was instantly hooked I watched eBay and bought the cheapest phantom 2 vision I could find that was in good shape and rtf for $750, ive since run across an identical one for $550, should I buy it and sell one on eBay to recoupse some cash for another battery or is it probably not worth the hassle? Was $750 a decent deal and $550 a steal? This hobby is so expensive saving a hundred or two here and there is huge! Also I ordered prop guards but maybe they're a bad idea because they cause prop wash? I've only run about 5 packs through my x5c should I practice a lot more with it before I try the vision2? Anything special I should know that I probably haven't found on you tube and google? I'm more into sport flying than filming but wanted the camera option and the bigger battery, that's why I chose the vision 2. I read the camera is not removable. I've built so many rc's I can't imagine that's true. Is it? I'd like to remove the camera for sport flying eventually. Also should I update to 3.04 or stay on lower firmware to maintain the 25m/s speeds? Sorry for all the noobie questions but I sure would appreciate thoughts and advice and if anybody wants to drive 1/8 brushless monster trucks or fly quads in Vegas hit me up!
