But is the price point comparable between purchasing vs building? You can get a ready to fly rig with GPS and a large enough lift capacity to carry a decent camera such as a go-pro for under $500.
Once you get the GPS modules, radio/reciever, all electronics and air frame are you really going...
I am thinking i might rather build my own quad for flying my go pro around and doing some fpv flying over purchasing one rtf. Thoughts? Price differences? Which would be better? If custom is better and price is not too bad, where to start?
