Hi Phantom pilot uk,
To be honest and i'm not going to spend anymore time messing with this drone,i think the best upgrade is to get rid of it and get a Mavic asap!!
I have a modified antenna already and it's just as useless.
You know what i think would help is taking out that useless 1s battery in the controller and look in to giving it more power somehow,but the fact that too is coded is very annoying,the battery has a microchip on top and needs to be calibrated to the controller

I am selling this..
So as of now i suppose i am better off to just reinstall the older version of DJI GO and at least get my map back.
