The package arrived in bad shape
The motors appear to be some OEM branded RCTimer 5010/14 360KV ones. As such... They are rated by the manufacturer at 4s. It's nice that the ESCs go to 6s but the motors may well not. There is a video on youtube that can help you build up the frame. It is pretty quick and doesn't show all of the details but it will help do most things (other than the hinges). The two side arms are longer than the four corner arms! And getting the arm hinges built properly took me a fair amount of searching for better closeup pictures on the Internet. But, hey, what do you expect? It's a DIY drone - there don't appear to be any good resources out there for building any of them! For me this is a good platform/base for building on. I'm not going to continue with it like this but it allows me to have a working drone and to buy other bits (real motors and props, for example) as I go along. I do kind of hope that my 6s battery doesn't fry the motors but I'd be OK with it - I have real motors coming.
