Arm winch servo

[Terry Connell]

The Hi-Tech servo HS-7980TH "Monster Torque" has failed in a Psycho. It was an arm winch servo.

It was programmed to rotate through 180 and had it's failed voltage reduced/set at 50% .

Where can I get a replacement, please?

Thanks.

Have you opened it up to see what's wrong - sometimes the motor wires break and it's an easy fix.  If electronics aren't your thing then I could take a look at it for you.  Message me if you want.

Each to his own but I'm not a fan of arm sail-winches.  If you use 180 deg travel then the sheet travel is almost zero at both ends of the servo travel.  The sheeting force will also get huge at fully sheeted in and could break something if you let it over-travel.  If you can't afford (or get hold of) an RMG then the Kingmax winches are very good value for money.  Sure they are a little slower than an RMG but they are easily powerful enough for an IOM - I use one on 10R.

There are various suppliers of the Hi-Tech servo HS-7980TH "Monster Torque" servo on the internet, You may need to search a few sites as some currently are waiting for stock. However seeing you are in Eastbourne cannot either Ken or Trevor Binks advise you?

John, I am also a fan of the RMG, however my current boat is fitted with the Hi-Tec arm winch and I have been convinced  it is at least a match (may even be faster, possibly too fast if I was using more than 6v) .  The geometry also gives the more accurate sail positioning at the end points without having to resort to radio programming. It is no surprise that my current boat has this winch as it was originally owned by Trevor Binks. (I did wonder if I was doing the right thing buying the boat, but it was a Britpop at a price I could not refuse)

Funny thing is my previous boat (still have it) was  Barry Chism's own Psycho. (RMG fitted)

Also a fan of the KingMax winch, using that in a Marblehead.
