I caught the itch its official! I'm flying a nano qx right now and its a blast but I want to start getting into custom builds. I really want to build a fpv racing quadcopter so I'm looking for kit ideas that are easily upgraded. I also want input on batteries, I'd really like to have the high C rating battery for obvious reasons, but also want a setup where there is longer battery life in the 10-12 minute range just for practicing and cruising around. I'm not sure if this is ideal at all but was hoping for input.
