Hi, I have a Vers 3 - The Camera broke and <long story> so I bought a used one whole drone off ebay to get the camera off it and to use the other bits for spare parts. Just received it today and found its a Version 2. Looking at the differences between the two, looks like I can take the cam off the V2 and put it on my V3 and all will be ok. This leaves me with a working V2 (minus camera). I know the differences between the V2 and V3 is the motors, compass, properties, remote. Question is: Should I keep the V2 and use it for parts/spare drone, or apart from the above parts are there going to be other incompatible parts and maybe I should put it on ebay to re-coup costs?
