That's how I initially envisaged my set up. Two sheets on one winch which was divided into two. I set the sheets up so one turned clockwise and the other anti clockwise so as one wound in the other wound out.
However, as one wound out and released the sail, the other sheet was winding back in and tightening the sail, unless I was missing something.....?

I will let you know how it goes and hopefully get some video footage.

Look forward to seeing it sailing and how the winches work. I’d made one of the Flyer models and two winches worked fine. The one controlling the jib, would let out one sheet while pulling the other side in. Used the same system on the Katie pilot cutter I built seems quite reliable

Good luck

I have solved the problem, I hope!
I have read read the instructions many times and disregarded the opening gambit "Two sail winches for the mainsail, one for port and one for starboard."
Fourth paragraph reads "Prepare both sail winches (one for foresail and one for jib), by fastening the sheet rope on the drum and wrapping it round twice. Also use the remote control to set the winches to completely lowered and insert the drum. Then pull the winch in and so wrap the sheet rope tight. Incorporate a small ring on the sheet rope. The port and starboard sheet ropes are placed on this ring."
I understand this to read 'One winch controls the jib, in and out, and one controls the foresail, in and out.'
All will be revealed on Wednesday when I propose to launch.

I cannot see why you need a port and a starboard sail winch unless they do something else as well?

Hi thanks for the post but I cannot read the writing! Can you PM me the text and I will see if I can get it so I can read it?

Hi Ron I use extension arms on servos as well. The fore sail system control I explained is separate from the mainsail and jib control. It is easy to implement.

I use winches and also the self contained winches that do not require an external loop and arm winches depends, what you have room for.

Roy

Yes, good idea to use a boom with the jib.

I do not use sail winch systems but tend to use a long or modified control arm. Maybe one of these days I will give the winch a try.

A very easy to follow video. The deck layout of the sheets is very similar to mine. However, very different below decks.
Oh that I had seen this before getting the stage of the build that I am at!

Have you watched how Gary tackles the controls for the extra sails?



You can begin an email conversation with Gary as I find he has a wealth of knowledge.

Thank you for that, I may very well copy you.
Having read Variant 1, which I have attached (left hand side of the page) for your info.
Though I have mounted all three servos as per instructions I am still at a loss.

Thanks Dave. I too have come across this series of videos (after much searching), but it really doesn't help with the connection of the three servos.
The first line of the instructions (translated from German),
"Variant II.Two sail winches for the mainsail, one for port and one for starboard."
I have attached the rest of the page.
Is it me.....?

Hi, having looked at the finished model I would recommend a boom for the jib, it was common practice full size and makes sure the sail does not fold up on itself.
Another solution is to slide a very flexible length of piano wire through the seem of the lower part of the jib sail.

Hi first of all looks great on the water, very nice.

I have a similar sail set up with a slightly smaller yacht which works well. I use just one main sail winch, this is for the main and allow parallel travel for the jib.

I mount the fore sail on loop so that it swings either side of the jib a sort of halter. I tie one end off on a bowsie on one side of the hull to allow for just how much movement you want and the other end through the eye in the foresail but not attached to it across the jib forestay and into the other side of the hull.
I allow enough movement to easily cross the jib if there is an overlap.

I bring this other cord end in to a second but standard servo with an extension arm say 4 -5 inches long. Suggest this is mounted on its side to allow a vertical movement of the arm. You will need another access point to get into the hull, try and keep them in line.

The servo is securely mounted and the free end of the cord attached to it.
The movement of this servo will tighten the fore sail and flatten it.

When sailing / tacking allow the adjusting servo fully out and when onto the new course bring the sail (standard) servo in until it flattens the sail i.e. just stops fluttering.

This will dramatically improve the efficiency of the jib and main. You can see the yacht gain speed, so the fore sail is not a decoration but a working part of the rig.
You may have to adjust the other end of the line with the bowsie to suit wind condititions.

It is best if you can use a transmitter knob or lever which does not spring centre. I have some 3 ch. 40Mhtz sets with the third channel a lever at the top of the TX which I can activate with my finger and it stays in position. Try for the lever coming towards you and the servo flattening the sail.

It becomes second nature when tacking and a modern sail winch will handle the other 2 sails easily.

Hope this helps

Regards

Roy

I had a similar problem with my Robbe Atlantis and it took a lot of searching other sites and U-tube before I found the info I required. There is a U-tube post in about 4 parts and the last one does show the mainsail connection if that is any help. Part 5 show even more detail

In my experience multiple sail controls become difficult to use at any distance and although I have used them I have replace with free setting jib/foresails or they are linked to the mainsail.
Hopefully someone on the site will have more info on the actual model
