    Yeah, exactly, this crossed my mind, but I didn't want to speculate, guess we will wait for Steven to clarify.
    Since it sounds like you are familiar with the more expensive Arrowshark unit which I am not, are the bevel gears machined in such a way that it can only go one direction?

      No the gears in the AS unit are straight cut, so you can spin them either way.

        Straight from arrowsharks website:
        The M8 gear set is not machined from just standard hardened alloy, but from alloys made with a compacting process of powder metallurgy; this is the same technology used for gears in full size automotive transmissions.
        The gears have thicker and stronger teeth designed to permit engines up to 10hp to be used for blistering speeds. As well, the gear design allows for counter-rotation when you go for the ultimate and fit twin M8 drives on your boat.

        SO if it's made like the AS unit we are good to go:)

            Hopefully it's gear driven:)

              Hi Steven and moderators,
              I just realized I got carried away a bit , please delete my posts if you deem necessary, I didn't mean to go off topic here in the TFL product thread.
              I love these units BTW, they are as I said earlier beautifully made and I have to find a hull to do justice to them!

                I am making this a point because I want to build a twin Out Board Pursuit and i have the TFL mini OB, the problem is no one makes a custom CCW cable for that unit, it is square end 4 mm cable. I have been researching and so far no luck, therefore I am flying Multi Rotor Quads to kill my time . lol.....

                  yes the gears are straight cuts. here is a parts diagram.

                    Wow, so they really are gear driven, and it looks like all solid shafts, so no need to worry about unraveling a cable!

                      That's what I was assuming as well based on the shape of it all. Good to know it really is gear driven. Wheels are turning for this. I'd think they'd be a little small for mean machine, no? I'd like a more scale looking hull though. Maybe even a twin pursuit instead of a cat?

                        You may absolutely correct, Mr DCMW! Keep an eye on here, you will find out the truth. :--)

                          can you post the dimensions of the unit.
                          Thanks

                            Hey, thanks!
                            I will ask, last when I investigated, the strands are not identical, they don't feel the same in my hands. I would have gone nuts with that situation. But may be just the one I got?
