This is ancient 1/16 tank parts. No idea if they work or anything. I don't know anything about these. It looks like it was broken off of another tank with some damage to the wires and plastic. I would put it in the bin but trying to raise a little money.
It also comes free with parts from a old Sunny Smile tank (the top, flag and a metal rod with wheels on both end).
And brand new 4 gears for a model kit, never used.
Also open to trade it all for 1 essential item.
If you are wondering why it is only £3 and pointless, I am trying to raise money for art supplies and every little helps.
