if you just want it to fly on the latest suported firmware then you can get a f405 controller for under 30, if you want all the bells and whistles like lua scripting then you need an H743 controller and they are around 70-80.
Thanks for the reply.
So, with the F405 controller, what else do I need for it to fly?
I assume it wont have anything like GPS or anything fancy.
The drone has 6 ESCโs. Will that controller support it?
Sorry for all the questions but I am not clued up with this at all.
I donโt think you will get an answer to that. A much newer flight controller than that, the APM, has virtually no support because no one remembers that far back. You are in the stone age with that one.
Or are you asking about configuring a new controller? If so there is a standard procedure to follow.
