    I am putting the tyres onto the tug now... A fiddly job.
    I intend to do an few changes to improver the manoeuvrability in reverse. A gent on YouTube did this by scrapping the engine control and fitting 2 ESC units and new supplementary receiver. It worked well but cost quite a bit and he ended up using 2 controllers which seems a little over the top to me.
    I am working on a simpler device.
    My plan is to add a sort of mixer. And a second motor drive ESC equivalent. The main difficulty is that the boat does not seem to have a conventional ESC and therefore the normal 1-2 msec pulse is not accessible. So a bought rudder to throttle mixer is not going to work.
    I am not too worried about going forward, the rudder is OK for that. But going backwards is a different matter and I intend to address that first.
    I will make and fit a copy of the present H bridge motor drive. This is driven with a PWM F and PWM B signal- forward and back.
    So now there are 2 motor controllers,nboth in then first instance driven identically.
    I can sense the rudder position and intend to break that down into 3 areas, small medium and large deflection. Small will do nothing. Medium will stop one motor depending on rudder direction giving reverse while turning. Hard over will reverse one motor which means it will go forward and the model should turn without any movement. Throttle setting will be as determined by the normal controller setting so speed control is not lost.

    Any comments or advice welcome.

    Hi SC,

    There are a lot of posts on here about smoke generators. Try searching in the forum, and the gallery. I use glycerine in my smokers. Thinned a little with water to reduce the viscosity.

    As an extra. I contacted Hobby Engines and they say to use train smoke oil. They also say that the coil will not burn out if there is no oil loaded. They sent a circuit but I think its for an older model as the connectors shown do not line up with what I have. But what a nice friendly company they are!
    Another web post claimed to have measured smoke generator temperatures and only seen 100C. I believe the heating device is like a wire wound resistor. These easily get to 250C and then the solder holding them to a PCB melts. Cue crimped connections.

    Sailed it for the first time today. After web research it seemed that baby oil was the stuff to use. Train smoke oil is expensive and does little more. Paraffin know also as mineral oil is nearly the same as baby oil. Unfortunately the best webpost simply concluded that one does not see much smoke. And so it proved. Oil all over the place to start with and not a hint of smoke. We need to get a VW engineer on this job and find out how to produce smoke properly?. Could I just use diesel oil? What can one add to produce smoke colours?
    Any ideas or information out there?

    Thanks, looks like I need to find cutters and a switch!

    Hi:

    Bear with me; I can’t see very well.

    I have the tug with the smoker. There’s no way to unplug the smoker or turn it off as supplied. You can disable it by cutting the two wires that power the smoke blower motor & the two that power the smoke generator itself. You’ll need to remove the deckhouse bottom cover & cut the two pairs of wires I marked in the attached photo. The smoke blower is in the upper left in the photo; the generator is on the right. The blower pushes air to the generator through the tube with the wire coil on it.

    I’m revising my tug to add switches for the blower & generator as soon as my vision is 100% again.

    I hope this helps. Good luck.

    Pete

    Please tell me, does your model with no smoker have a 2pin connector under the wheelhouse that is bigger than the others? If no smoker it must have less wires than mine and logically the extra ones must be for the smoker. But mine has so many more lights than the original that a comparison cannot be certain. But lights only need small wires and I'd expect a smoker coil getting hot would need something rather bigger.

    Hi Seamancook,

    I'm hoping there is a way to disconnect the smoker!
    I have the Southampton without the smoker!
    But, I do know!
    Don't run the smoker without oil!
    You'll damage it!
    Try to see where all the wires go!
    If possible disconnect the smoker!

    Oh, don't over oil the smoker as well!

    Cheers, Ed
