Derek we ran the Red duster up the port side halyard the White ensign up the stb side the Blue national flag from the flagstaff with my neighbors flying the Australian flag at Jamie's place and Bruce flying the Union Jack down the road becoming a tradition both Remembrance Day and ANZAC day all ex sea farers in one street , back to the Tid Tug I like to run cooling water over the side as a feature of the model and use the water as cooling coil around the can just to aid the cooling not that I think it will get to a point of overheating rather a useful detail , i run computer cooling fans over the motor and the ESC just because it makes sense in my mind being an enclosed environment with heat etc just one of those things i do I suppose, one feature is when the head door opens via servo the crew member sitting on the head the pump via switches discharges water out the stb side light turns on as well , nemesis I will look into gearing it down did think about it was going to do some testing when installing the motor tons of room in the hull many thanks for your input crew regards tassie48
