hello So my stock (advanced) controller is no longer an option. It's deceased! Ha. So looking to buy another. eBay seems to sell right around $200. Give or take. So that being said I have done a little research into aftermarket controllers and was wondering if anyone had some advice on the subject? Main reason to go aftermarket would be to try and get more distance? But that's where I get lost on the info. I've tried reading and learning what I would need. The up and downsides. The work involved ( do I need to change out interal stuff in drone itself? ) anywAy. Just looking for a few simplified answers ? I realize price will be more, but I'm open to thAt depending on the benefit? ThAnks for any help.
