I bought a job lot of bits and bobs, and in it was this Phantom 4 controller, model GL300C.
The previous owner has stripped the battery and power jack (under the gromet on the lower right side).
But the sticks, buttons seem to be in good order. It still has the selophane on the phone mount. The controller looks in good condition.
I have no need for it, so if anyone can make use of it … they can have it at no cost.
Message me if interested.
