hi Ron only noticed afterwards you are in Canada. If you try your on-line access to US aircraft RC spares and accessories you will find the more powerful servos now available all in standard servo sizes. Otherwise I expect postage from UK too expensive.
They are usually metal geared servos with more powerful motors, however these are fast and can be slowed down.
There are 2 ways. You can buy in UK a servo morph which selectively slows the action down. Action Electronics in UK make such a kit, possibly they have an outlet in USA or Canada?
The other method is a bit more radical and involves the Transmitter.
If you obtain a high value capacitor say 500 micro farads and put 2 small clip connectors on the wires. Take the back off your Tx. and work out which pot is the sail winch control and clip it across the terminals of the pot it will slow down the servo operation. The passive capacitor will not damage the electronics of the Tx.
If this is not enough then try a higher value.
I did this about 30 years ago and it works OK.
If this works for you then you might want to wire it in permanently with a switch to disable it for other uses.
The servo expander is very small about the size of a servo connector pair and seems more available now, it connects in as I described.
I did not show a picture of the RC in my Bella now called Pelican, see my harbour, as it uses a sail servo that is over 60 years old.
It was originally in use with about 20 others to control air flaps in a wind tunnel at the UK Building Research Establishment. The unit fell out of use and was dismantled and the servos were removed and under someone's desk for years until a clear out happened. A good friend of mine then working there and into model boats obtained them.
I had 3 or 4 of them, I had to adapt the o/p shaft and also I took them apart and inserted miniature 1000 ohm capacitors at each of the ends of the rotating potentiometer. This also extends the throw of the servo but a bit radical these days. This was done 20 years back when sail servos were specialised and expensive.
The servo lead was also changed for a modern one as the electronics were compatible with the current systems.
They were already slow and make perfect arm winches for my size of model yacht.
So not much point in showing photos, as the servos are the last of their kind. Having thought about it I believe 'World Engines' did the electronics.
