    Great video Kermit, I like the slo-mo’s

    Have you been getting video lessons off Moose as well?

    Nice video Kermit, well done. I think your video quality has improved after washing your camera.

    P.S. The flying lessons you got of Moose certainly paid off.

    Rudder tubes installed, again using another 3D printed jig to hold them in place.

    There will be a support added near the top of the tubes as well.

    Shouldn’t be any prop walk, counter rotating props!

    Shaft Install.

    Next problem is to align and install the prop shafts into the hull, they are 235mm apart and are separated by the tunnel.

    To keep them perfectly aligned I made some 3D printed jigs to hold them in place while glassing them in.

    This one lines up the motor with the prop shaft.

    To space them correctly and to be able to adjust the height, they are joined together with this part,

    Next is this jig that holds the shafts on the outside of the hull,

    Like this,

    The inside jig in position

    The tubes were roughened up with the Dremel and to seal the outside of the hull to stop any resin seeping through I used something that would never leak – Joysway’s Hatch Tape!

    It was then just a simple task to glass the prop tubes to the hull,

    Great video’s from all. Looks like I missed a good day.

    Good to see Moose’s Epoch back in the air, but a shame about the Fox.

    Thanks all for the encouraging words.

    Next job is to install all these parts.

    Rudders,

    Again there is nothing commercially available, so for the tubes I used the same size stainless tubes as the prop shafts.

    Brass bushes were turned up on the lathe and held together with Loctite.

    The rudders are made out stainless sheet and some more of the 3/16″ shaft silver soldered together.

    After a lot of shaping, cleaning and polishing they look like this.

    Who’s Kermit?

    A nice peaceful day at the field.

    Well done Mike, Ralph Jnr. looked good at that speed!

    in reply to: Cougar Cat #9942

    Thanks Moose, but I should be OK.

    Next bits,

    As this a large boat so I will use standard 3/16″ Props, as these a easy to get and come in lots of different sizes and pitches.

    The only trouble is they are normally used on fast racing power boats and they tend to use flex shafts.

    This makes it very hard to find a solid 3/16″ prop shaft, so the only option is to make them.

    I used 5/16″ Stainless tube with a 3/16″ stainless shaft running in some brass bushes that I turned up on the lathe.

    Made the support struts out of scrap brass & tube.

    The couplings also needed bushes in them for the shafts.

    Now all I need to do is fit them in the hull.

    Aren’t you supposed to be fixing the shack?
