Can you help me choose a linear actuator?

[MigGat]

Regarding the angle, it seems this unit has a bit more than what I currently have, so that should be good I guess.
It also can push 85kg vs my current 77kg, so that's a win too.

Regarding the installation, the current one is a bit more aft than it should, but i think the previous owner had to trade between optimal mid-stroke point and stroke angle.
I will consider adding a new position to attach the pilot, so I can correct the angle (didn't know i could add an offset).

I would suggest for upwind to mount the pilot farther from the rudder shaft, and offset to either port or starboard if there is weather helm. For downwind, move the pilot closer to the rudder shaft.

Of course if you had a very fast, strong actuator with lots of travel you would never need to move it around, and most people dont, but if it is struggling you could improve it this way.

So i finally bought the pcnautic tiller drive and Sean's motor controller (a while ago, but didn't had time to play with it until now).

It works fine, even the remote controller, which a use with an ESP32 with a super cheap XY-MK-V RF receiver.

But I still have 3 cables comming out of the drive unit that I don't know where to plug 

Acording to this (https://pcnautic.nl/nl/autopilot/raymari...ent-detail), the unit has end switches.

   
   

So now I need to know which wire goes where in the motor controller. Any help, please? 
Thanks!

you could run the wires to the rudder feedback or omit them initially since rudder feedback is optional

[MigGat]

Awesome, so just like this?
   

How do I know which color goes where?

I found this diagram talking about this tiller drive, so I guess colors are correct?

You should check our manual and then the pinout from Sean https://pcnautic.gitbook.io/autopilot/in...controller
So White to Ground Red is signal and Yellow +5Volt

[MigGat]

Great! I never found the https://pcnautic.gitbook.io/ site in all my searches, but it'll be very useful

So according to your info and Sean's schematic, and if i'm not mistaken:

1: White
2: Red
3: Yellow

Yep pinout is ok! But your link is wrong you do not need to log in for reading the gitbook manual, use: https://pcnautic.gitbook.io/autopilot/

[MigGat]

Awesome, i'll solder the connectors this afternoon and try it

I use this from AliExpress 300mm stroke. with 60 mm/sec speed and 100N force. Work well on my 20" Dufour T6. It has a potentiometer on it, that works well with the Tynipilot. They also have the same model in 500mm stroke.

I install it with this controller
