Hi, I`ve got a Jcc in my Smit Zeeleeuw (nangi). I have used 8mm pipe up the funnels attached to a fabricated "y" piece of same size and material. I then used clear tubing for a flexable joint as I need to remove the cabin, this then goes onto a 8mm to 22mm converter (manufactured) into the unit.
When running off 6v the unit runs for around 35Min's so far, as this is only a bench test. As for sailing unfortunately i forgot to take a warm flask of water as it was a cold day, it doesn't like the cold :( (same as most of us). I ran the model on the water for a good 1/2 hour on 6v but didn`t know if the unit drew any current due to no exhaust smoke.
I`ve heard that you can put black food dye in the water to give black smoke, is this possible ?? as i don't want to damage an expensive unit, In the instructions it says don't use coffee (cos it leaves a sticky residue). If so where can i get some as the local cake shop says it doesn't exist!!
Hope this helps Dave
