I have no idea as yet how the R?C unit works.  I have 2 and 4 turn sheet winches, a steering servo, transmitter with matched receiver . . but I assume the receiver needs a power supply.  No idea.  Help please !

You will need a receiver power supply to power both it and the servo and winch. The standard is a 4.8V NiMh pack , these are sold as receiver packs. Alternatively you can use a 6V NiMh pack also available as receiver packs. The 6V would probably be better for driving a sail winch as they use more power than a servo.

JimG . . thank you, but . . and this is a complete novice asking . .
Seems I go find a battery pack and plug it in somewhere, but no idea where.  Do all 3 bits somehow connect to this battery pack, and I assume differing voltages will not harm ?

The instructions, for what they were worth . . . said virtually nothing.

Many thanks

Hi Jon, basically the receiver has a set of connectors on the top, these are for connecting the servos and battery to. The plugs on the end of the wires from the servos and sail winch plug onto these connectors and receive power and the controlling signal from them. The connectors are generally numbered with one of them labelled BAT, this is the one where the battery connects to. The voltage of the battery is not too critical as most servos can take up to 6V ( this allows for 4 non rechargeable cells at 1.5V each..)  A rechargeable battery is recommended to power the receiver and servos as they would soon flatten non rechargeable ones.

Hi Jon,
An on/off switch would be useful as well. You can buy a switch harness which has a plug on one end to go into the receiver as Jimg has said, and has a socket on the other end for the battery pack to plug into.  Some harnesses have a second socket for charging the battery pack but that's optional as long as you can reach the batteries to unplug them for charging.

So very grateful . . this is all beginning to make sense . . . at last.  Simpler than I thought.


Off to the model shop soon to get a battery pack and a switch . . then I'll give the winches a try out on the desk !


I bought 2 sail winches, a 4 turn and a 2 turn . . which give 12.5 inches and 6.25 inches of travel.  The sails of course are all of different sizes so the plan is (at present) to fit a boom under the larger jib sail with a 2-1 block from the sheet, similarly the mizzen, and a 1-1 on the main boom . . again I will rig up a testing system prior to installing.
I'll post pics in a day or so as off out much of today


Again . .  thank you for the much needed help

Pics so far . . nothing is fixed in place  except the vertical framing and a few outer deck planks

I need to find a way to connect steering servo to rudder . . and a small pulley and tension spring near the bow to give about 14 inches of line travel

Calcs . . . .
