Photo #1 shows a 2 channel Futaba receiver connected to a standard Futaba servo for steering. The 3-wire lead coming in from the LHS of the piccy is from…..
Photo #2, which is an Electronize electronic speed controller. This should be plugged into the spare socket in the receiver.
Now it gets hazy………..
I can only speculate about what connections were intended to be made by the builder. What we would really need is a sketch of the connections which are made to those two switches and to those sockets affixed to the switch plate ahead of them. See Photo #3.
That board under the S/S is a total mystery – I’ve never seen a commercial one like it. The battery connection looks like a 9v PP3 clip, and is there an on/off switch at the end of the green wires? The detail of the board is fuzzy – are there fuses on there?? Photos #4 and #5.
On balance I think it might be best if you were to settle initially for
what we can sort out i.e. steering and forward/reverse + speed. The lights are a secondary issue and, unless you use a manual switch to
turn them on and off, won’t be useable with a simple 2-channel set.
Do you have any details of the motor and prop which are fitted?
