AR Drone 2.0 Rebuild

I wanted to rebuild my AR 2.0 drone I just started arduino and was wondering if i could keep the drone body sonar and optical sensors intact and redo everything else from scratch.I was wondering is it possible to keep it wifi or should i just go rc i want to learn it all.

Any suggestions?

Get PS3 controller driver for windows 10 "AutoFlight"
You download PlayStation now 5 day trial it gives you the driver. I think if you just cancel it and leave it on your computer you should be good. After a day or 2 my controller was acting finicky i just reset it and it works flawlessly now

ps i need some advice on an ar drone rebuild
