Not wishing to tell fellow modellers how to suck eggs but having built two Kort drive tugs , one single and one double , I would like to offer some hard earned advice on Kort drive protection once installed .
I bought a ready made hull from a Tug boat supplier along with a set of 50mm steerable Kort along with all the recommended bits and bobs , but in spite of this found that one of the resin cast Ports became so oval as to be a serious problem and in need of replacement .
Further work was entailed and in the end I became distrustful of the material and asked Protean Design to assist .
They were very helpful and produced new Kort's made of aluminium and at me request fitted a pin in each of the bottoms so that I could fabricate a Skeg set up to protect the Kort base from accidental damage .
This they did at no extra charge and I made up a set of parallel arms which on a piston principal kept them aligned perfectly and I have had no further issues with the set up and regally act as the clubs recovery Tug at club meting should they require recovery to the shore line and would recommend this system to any Tug / Kort drive system model boat owners .
In addition I have recently upgraded the props to 5 blade units which work very well indeed .
