Hi all, I took the plunge and sawed off the upper bridge deck. It was glued on with 'hot glue' and very strong too. I can see how to turn it around, so O.K with that now.
The prop shaft is non standard as the ends are threaded!!!! I tried removing the tube but it was stuck fast.
I found a 4mm shaft which is a good fit and have used the Deans prop tube mix in the tube, will test tomorrow to see if there is any water incursion.
I am fitting a slow turning Buhler motor and a 4 blade 40 mm prop which on test looks fine and very low current but churns up a lot of water in the kitchen sink.
The Buhler motor is labeled 12 -18 volts, it is slightly bigger than a 540 motor and I tested on 7,2 volts. The measured on load current on 7.2 volts was just 0,25 amps, less than 2 watts! Motor stall current was 1 amp.
I think I shall make up a 12 volt pack from 2 off 5 cell packs. I think 7.2 volts will give scale speed but I like to be able to stop quickly.
Does anyone know the displacement of the model? Looks about 5 -6 kgrms.
I am missing the main mast so will have to make another one, can you get odd fittings from Caldercraft kits?
Thanks again for the pictures. I have also found tug-kennys build blog, very useful.
regards Roy
