hi mate.
leave the control arm where it is on the rudder and put it on the opposite side of the servo arm,
this will mechanically reverse the servo.

ok so i finally worked out where to site the steering servo so it works correctly. the servo is secured and works fine. apart from tidiying up the cables before i secure them, does the receiver and the ESC look like they are in a good position?
thanks

It looks like it will hit the hull when steering to Port.  Please tell me I'm wrong.

you are wrong, it wont Ken, it just misses but it gives me even steering from l to r without putting any strain on the servo

Phew    :}

The reason I wrote was that I find my servos need at least 50 degrees each side of top centre.

Glad it's OK.

hi mate,
your receiver and esc are both on the bottom of the boat.........
.I would have put them on the 'sides' as high as they would go .......out of any influx of water.....also in balloons.

On the other hand, should it flip, they will then be at the new top, and might assist with self righting.  An ESC inside a balloon might suffer with lack of cooling airflow, and in a fast boat its normal to tape the lid for waterproofing.

Looking at the angles of the rudder servo and linkage you might end up with uneven throws left to right..... but it might just be my heli experience kicking in.... servos at 90 when centred lol

its as close as i can get it. its pretty even both ways within a few degrees. unless i buy a new servo, which i cant see will make any difference, i will have to stick with it

As E2V says, this is how you can set up your rudder linkage.

The Servo arm should be of equal length to the tiller (rudder) arm.
  ie. the length from the centre of the servo spindle to the hole use to connect the link - it should be as near-as-dammit the same on the tiller arm.
  iee. The 2 blue lines should be of equal length.

The neutral position of linkages should also be offset clockwise by about 20 - 30o so that you have equal throw left and right , without toughing the bulkheads.
 ieee. The angles between the blue and green should be 90o

Should do... unless you are going backwards too fast!

Make sure the lid / cover is secured to the hull with string etc. and has flotation in case it comes adrift.
Also, fully check the hull for leaks in the bath... mine had several!  >:-o

so you are saying i should move the servo arm to the right a bit more? i am a bit confused

Yes. Reposition both arms as in the diagram, and reset the rudder to neutral in this new position and test.   :-))

Ideally, with the rudder set straight, if you draw a line from the rudder post to the servo pivot point, both the servo arm and the tiller arm should be at 90 degrees to that line, preferably facing the same way.  The connecting rod should then be the same length as the post-pivot line.  If the servo arm fouls the panel, it is permitted to shorten it and use a hole nearer the pivot point.  This means drilling a new hole to correspond in the tiller arm.  Expect a servo throw of about 45 degrees each side.  A rudder throw of this size is usually more than adequate.
