I was gonna say that body looked pretty well detailed for something a little more "vintage". Plus it's still in pretty good shape
If that Kysho came with a half decent "trickle charger", you might be able to get by for the time being. I'd still double check it can charge the batteries you have. If it will, you might just need to get a Deans plug onto your charger or make an adaptor for it.
Dropping a little $$$ on a decent charger will save you some time, and could help keep your batteries happy. Just keep in mind the type of plugs you have (Deans), and what will come with a new charger. Not all chargers will arrive with a Deans plug or adaptor. But, they are some of the better plugs on the market. Not saying always the easiest to pull apart
........but they do their job well
