The pull-pull cable linkage for a standard servo (20 mm) is designed to be screwed to the rear former. Three M3 screws are supplied for this; they pass through the former into the T-nuts of the mounting plate.

A central M4 socket head screw tilts the swivel unit with the servo forwards or backwards. This makes it very easy to tension or slacken the cables running to the rudder. The annoying and fiddly adjustment with crimp sleeves and clevises is no longer necessary. Once the cables have been installed correctly, cables that are too slack or too tight can be corrected in seconds.

The mount can be installed completely hidden behind the former. To do this, a slot must be cut into the former to give access to the socket head screw. A drilling template can be downloaded here as a PDF and printed out (German). Cut it out and stick it onto the former. The holes in the former can then easily be drilled from the front.

The formers we supply already have these holes.

A spring keeps the swivel unit under tension, so the socket head screw cannot loosen or move. The setting is therefore retained.

The adjustment range is 10 mm: from the zero position, the swivel unit can be adjusted 5 mm forwards and 5 mm backwards. This can be influenced by how the cables are set up.

On the version with sliding carriage, the plate with the servo can be unlocked via a spring pin. The carriage with the servo can then be pushed back by 25 mm, and the rudder can be pulled out to the rear together with the cables. This makes the often hidden clevises much easier to access.

When assembling the model, the clevises are hooked in and the servo is pulled back again. The spring-loaded pin engages in a detent and is operated mechanically. It snaps into position automatically, and the cable tension is exactly as it was before the rudder was removed.

The cables can still be adjusted as before.
