Hi there

I too would be interested to see how the stabilisers performed in a video .. due to the fact that when I built Leeds Castle, which had independent control of stabilisers which worked from a free swinging pendulum, mounted into the centre of stability axis of the model, and this pendulum has sensors on it which picked up which way the pendulum moved.  The problem being, you cannot get the model to respond and roll like a 'real' ship as the model movement tends to be too quick and jerky.  Therefore the sensor system used to over react and sometimes you could get a quick corkscrewing movement out of the model.  Other times it wasnt noticable, you could see the stabilisers working but the model not really responding. The Leeds Castle is 1:48 scale.

hi there 3rd attempt hope this works

3 photographs of the internals of the LEEDS CASTLE - first one should be the pendulum which is mounted between the 2 main drive motors

2nd one should be of the part of the electronics which basically is a heavily modified servo driver

3rd one - 2 drive servos which drive the stabilisers independently

Joe, utmost respect to you for a job extremely well done.

In Naval parlance: BRAVO ZULU!

If I'm correct in assuming that you sail on Walpole Lake in Gosport then I look forward to seeing COVENTRY on that lake soon.

We launched our version of War Department Train Ferry No3 on that very lake today and were blessed with good weather, calm water and light winds, critical for a vessel with such a low freeboard.

Whilst discussing the stabilisers on HMS COVENTRY I'm reminded of a sad tale regarding her sinking and her stabilisers. As the ship's company abandoned ship, her First Lieutenant was almost last to leave. As he slid down the heavily listing ship's side, and being uninjured, he apparently caught his chin on a still extended stabiliser fin, was seriously injured and perished as a result.

Our thoughts go out to his and all of the families bereaved in the Falklands Conflict, especially as Armistice Day approaches.

Your excellent model should be a fitting memorial to those lost aboard the COVENTRY.

Kind regards,

Sandy.

Hi Sandy
Thanks but there seems to be some confusion Coventry was completed 18 months ago.
