hello,
where I live I need to go really far to fly 》250grs drones. Having lying around a full dji air unit and some other parts I experiment with some bottom plate of a novice 3, some 1106 a zeus and one top plate phantom 2.5".
some zip tie and double side tape to glue the fc and here we go!
As expected at 3s 450mah top mounted it fly....more or less. It is quite heavy not for racing or free style but just for relaxed fly is good!
