Hi i have a few of these items and i was wondering if any of you scale builder could tell me tue use of them.I think they are for like wiring up lights for your planes.The item under the #1 goes into the white plastic box.My guess would be that a wire can be screwed under each of the screws.on the backside of the board is the name High Sky.The item under the #2 is about the same and it does have info on the board as to where to solder the + and - of a battery.Are these still being used?? Thanks for any help !!
