Simon - Model Radio Workshop - Southampton offer a range of switching devices, their "Standard Relay Switch" would do
the job at £18.0, which is more expensive than the HK job but is in stock.
My HK - FW190 has lights but these are permanently on.
Look forward to you "flashing " us as you pass serenely by.
If it is the model depicted in the video then I think the lights are permanently on which means they probably plug into a Y-lead from spare channel on RX. As you say there minimal info on plugging in and setting up.
In the video it is defined as "Super Scale"! What? 40 size at most.
Phil, In China 40 is SUPERSIZE! Quite small people in China you know.
Anyway called in at Sussex models today, they sold me a bunch of cables with the correct female ends so that I can plug up all the lights, combine the red wires and black wires to a HD servo lead and plug them in for a hopefully fantastic light show. We will see!
