These are the parts I think I need for a KV-1 with flash & recoil:
7305095 Tamiya DMD Control Unit T-08
7305094 Tamiya DMD Multifunction Unit MF-06 KV-1
4205024 Tamiya 1/16 Recoil Unit
4305611 Recoil Gear Bracket
3450179 Gun Barrel
7255033 Flash Unit
7305093 Light Unit
Is it possible to wire the Tamiya stuff to the HL recoil unit?
