Today was mild and calm in Portishead so I thought I would take the model for a sail. The photos show it on Portishead Marine Lake which is the main sailing water for the Woodspring Model Sailing Club. The light level was quite low and so the photos aren't quite a sharp as I would like, but I took quite a few and picked out the best ones. The model was motoring more or less continuously for 50 minutes and there was still still some life in the NiCd battery at the end, so the 5 pole 385 motor really doesn't draw much current. The motor was also barely warm by the time I finished.
As I mentioned above, I have had to set the tension in the rubber o-rings on the drive pulleys quite carefully. They are 1.0mm width o-rings which means they are quite stretchy and it is possible for the motor pulley to slip on occasions, for example if you hold the prop and then operate the motor. I don't think it was slipping while the model was underway today, but it is hard to know for certain. I have also bought some 1.5mm width o-rings which are quite a bit stronger and I might make up another set of aluminium pulleys for these in due course, just to make sure that the slipping doesn't become a problem.
Otherwise the Molendinar Pilot boat ran very well today. I need to get on with making a proper box for it and then I will be more inclined to travel around to float it with some of the other local clubs. So there it is, another model in the collection and maybe time to start thinking about the next build? Happy sailing.
