    What's wrong with threads are that they are spiral. So it is a possibility given enough pressure that you will get a leak because the tubing does not slip down into the root or minor diameter of the thread. It is better if the tubing slips past the thread to where the fitting is smooth and round.

    "Only thing about this thread that puzzles me is what does it have to do with Glue / Solvent?"

    Depends on what you are connecting to as that will determine the size of the connecting tubing (usually something like Tygon which is often used in fuel motors and has good strength, flexible, elasticity, etc., take heat pretty well, plus being clear to observe flow) which will stretch over almost anything.

    Actually a smooth surface is better than threads unless you use a plumbing putty type sealing on the threads. A barbed connection is best. A good fit is when the tubing has to be stretched and pushed to get over the fitting. Make sure that the overlap is good, at least 3X the diameter of the fitting. With a good fit you will not need hose clamps on these small diameter, low pressure projects.

    On the models I have that have water cooling I use 5mm bore copper or brass tube to make my pickup which I position approximately 10mm behind the propeller. If water cooling is required for both esc and motor I feed the esc first then connect to the motor cooler, in 50 plus years of modelling this has served me well.
    Cheers Colin.

    Excellent advice shipmates๐Ÿ‘
    Only thing about this thread that puzzles me is;
    What does it have to do with Glue / Solvent?๐Ÿ™„
    Seems to belong to the 'New water inlets being fitted' post!
    Guess one doesn't have to understand all the mysteries of the universe!
    Just go with the flow๐Ÿ˜‰
    Happy building Stephen, looking forward to some pics of the results.

    Another problem with using a scoop that is too small is that debris can block easily.

    I cannot promise to finish one project before starting another. I know, I tried.

    Probably will not be much of a problem (simple solution) depending on the water flow. If the scoop can take in enough water that causes pressure in the lines significant enough to flush the water through that would not be a problem. The scoop can only accept so much.

    If the scoop and input pipe are too small then there could be a water flow issue for either the ESC or the motor or both.

    Probably the simplest way to figure this out is to measure the ID of both pipes then calculate the area of each and add those numbers together. That would be the area needed (can convert back to a single ID) for the inside of the pipe and scoop at it's smallest point. This would be a minimum number. A bigger number will supply more pressure.

    Keep in mind that the Scoops flow will be virtually zero if you are backing especially for any length of time, for instance a tug going backwards pulling a ship away from a pier.

    I have several applications I use individual scoops or a single scoop both for supplying several units.

    I hope this works for you.

    I would prefer two because you will never be sure how the flow is being split and you might fry the ESC or the motor.
    You might get away with it after some rigorous tests to ensure that both components are getting adequate cooling, but there is a risk
