Thanks Brian. I was apprehensive about the curved coamings and thought I might have to leave out the tight curves at the ends but thin ply came to the rescue.

I like that design too and with the added torque it makes for a good rudder control mechanism.

Hi Ronald. I was looking for a micro servo with a bit more torque than the ones I'd got and came across wing servos and thought they'd be just the job due to their slim profile and way they mount which I thought would make things easier for installation.
The forces generated under power (due to its low speed) or even under sail (lightish winds only!) are only going to be low but it's good to have some in hand but was surprised that such a small and slim servo could generate 3.5kg of torque. I guess that with aircraft that the forces generated can be quite high at speed. ▲

The flat servo has a fair amount torque. 34-45
Did you have these servos on hand or was it bought specifically for this model? ▲

The rudder mounting looks good Chris.

That brass horn will look so much nicer than a plastic one.
I think mounted on the spindle like that looks perfectly in keeping with the hull. It will also make it easier to remove if need be, but as you've said, secure too. Will ▲

Thanks you are very kind, I was originally going to go with pintles etc. but couldn't find any big enough. Also using a spindle makes it easier to make it so that the rudder doesn't come off. Spindle is 2mm which I threaded to take the domed nut.
I've made the rudder horn now from 1mm brass sheet, so much better than plastic! Chris ▲

Excellent detail. That rudder looks like something that came straight out of a jewelry storeโso beautiful and incredibly precise.
Your level of craftsmanship is on another level. Truly impressive work. ๐ ▲

Thanks Bob and Will.
Not for the speed merchants obviously, but I'm glad to have built the Fisherman and Faun as they are so different to the the other Faireys in looks but mainly their construction. I'm certainly looking forward to getting the Fisherman on the water with it being sail and power. Chris ▲

Fisherman 27.
That is looking nice Chris, and the fixed superstructure will make it a lot more water-tight too ๐ Bob. ▲

Fair play Chris, she's really starting to take shape now. That jump from just a hull, to having a superstructure and decking on has made such a huge difference ๐๐

I think so. You forget sometimes that parts and materials from other model/hobby areas can be useful. I happened to come across it when I was looking for a micro servo that had more power than the one I used in Faun.
It's prompted me to have a look to see if any Tamiya vehicle parts can be adapted for one of my future builds. ▲

That's a nice compact little unit Chris. Should do the job nicely tucking into the stern like that.

Chris your drawing doesnโt indicate the manner in which the rudder will be controlled. Please draw or sketch that detail. Top Side End Orthographic

Yes, as you say only low load whether from power or sail. But even that servo will pull 3.5kg so plenty of power.

You'll suss something I'm sure Chris.
I would think you will get away with using a smaller servo, as the rudder loading of a slower, less powerful model such as this, will be considerably lower than the likes of a H31, or Rapier for example won't they. Will ▲

Photos of the full-sized Fisherman and the cockpit area and for the model. I did think of running a rod through the cockpit area but as it will be towards the centre of the model I want to avoid it if I can.
I think by using a wing servo, which is only 10mm thick and cutting out some of the balsa at the stern to give room for the swing of the servo arm I can keep the size of the boxing to a minimum and make something in keeping with the design of the cockpit. Servo should be arriving soon so I can see how that works out. Fingers crossed! ▲

Not sure what the finished model is to be, thus if comments are not fitting with your design then please ignore. Several of my sailboats have rudder controls which require two rods to pass through a cabin wall to connect with the servo control arms. The push rods are #12 aluminum knitting needles. I get them used for .25cents. ▲

Having had another look I'm having to discount using a snake. The curve of the stern and the balsa blocks I've used there mean that the bell cranks would be further forward than using a servo. With working models sometimes compromises have to be made.

I'm sure it has been a big build so far, especially as it's a scratch build, and having to figure things out along the way. You're doing a grand job of it though, and will be rewarded with a really nice, extremely rare model at the end of it.
I was going to say, how about a snake cable, as at least the servo could remain remote then. I know they don't give quite as precise operation as a directly acting rod (unless fitted as a pair), but on a slower model, it wouldn't be such an issue. ▲

Cheers Will. It certainly is steady progress. There's been an awful amount of work in the build so far and still lots to do including the mast and sails but I'm enjoying it as it's so different to my usual builds. Plenty of challenges and thinking required but that's why I scratch build.
One is positioning the servo for the rudder. Space is very limited due to the seating area and I'm probably going to have to modify it compared with the full-size by having some boxing. One option is to use an airplane wing servo which are slim and easier to mount (one ordered) or run a snake along the side of the cockpit from a servo in the cabin and a bell crank, but that brings its own problems.

Steady progress there Chris, adding small details like that makes such a difference to the model, and it's realism ๐๐
