Hi All, I have been reading like crazy, but just can't find the answer to all my questions, so figured I would try to post here and get some help from some experts. I have been flying a 250 racing drone that I got off banggood for a couple years now, it was a complete kit with a radiolink AT9 radio, no camera, CC3D FC. I am very impressed with this little drone and have crashed it like crazy and it still works great. So a friend of mine got me a camera and monitor for it, for Christmas and I got to thinking that it would be fun to build a drone that had some more features to it, and one that I would not want to crash all the time, keep my other one for that. So here is what I have and what I want to do. I already have the following, 250 frame, radiolink AT9 radio, Radiolink 6 channel receiver, MT2204 2300KV motors, plenty of 3S batteries I want my build to have the ability to return to home, position hold, return to home or land on low battery. So the first thing I really need some help with is selecting a flight controller that will work with what I already have above, and give me the new features that I am looking for. Can someone please give me their thoughts on what FC’s I should be looking at, and perhaps links to get them, with all the necessary components, GPS, power board, etc… that I would need for them. I have several other questions, but if I can pin down which FC I want, then I can bug you all with the other questions. Thanks so much for any help that you can give me.
