Ok, so a couple weeks ago or so, I had the brilliant idea that maybe I could make an end plug to attach to the handle, that could charge the internal battery. Did some testing, figured out which of the 4 contact in the slot at hte bottom are + and -, and attached one of my battery chargers to those to see if I could charge it. The charger immediate errored out because the maximum voltage of that battery is lower than the lowest its capable of charging to. No big deal I figured, I would search the vastness of the internet for a more suitable charger. Well, then I realized there was a major problem.

During this test, the charger must have pushed through more juice than some internal components could handle. The radio is on a constant charger loop, the rear LED keeps flashing while its off, as if the external battery is attached, even though it is not. And when the radio is on, it displays the charge icon in the top right (battery with lightening bolt). The radio still functions as it should, but this never ending charge loop kills the battery after about a day.

I contacted flysky, hoping that they might have a fix for me. No idea what that could be, just hoped. They sent me an unreleased firmware, which did nothing (of course, obviously a hardware issue). Was a little excited about that, but there seems to be nothing important in this new update (no sport mode or anything). In the end it was suggested that I contact the seller to get a replacement, which I will not do, because I received a free one already due to shipping issues, and would feel like a real douche asking for a replacement on something I didnt pay for in the first place. This messed up radio, will be my son's radio now (he doesnt use it nearly as much as I do), until a later time when I just buy another one.

But during this whole process, I did open the radio up to see if I could determine any physical signs of problems. So, got a cool pic of internals (which I have not seen anywhere on the webs)



I still have not given up on the cap end charger idea. Just have to figure out a smarter route of developing it. Also, I might devise some kind of battery door for this now messed up radio, so the internal battery can be removed and replaced, without opening it up. Cause (maybe obvious) without the battery, the never ending charging loop stops.



Update:
Holy crap, I didnt think I would find something like this, but this seems so perfect. All it would require is a small hole drilled in the handle.
