Flat sheet dive vanes
« on: February 10, 2017, 10:02:26 AM »

The dive vanes on the Jelly Bean are made from flat styrene sheet, with the operating rod made from brass rod. The plan suggests to simply epoxy the rod to the plastic sheet...that would probably work ok, but I'd like to make a stronger joint of it. Any ideas, lads?

Could you cut the planes from 2mm sheet copper or brass and solder the rods to it?
Be nice and strong then but a bit heavier if mass is an issue.

 Just drill a small hole in the rod then push a brass rod through the rod and the dive vane.

That's all right, Mr Ryan. My Morse is so rusty, I could be sending him dimensions on Playmate of the Month.

'L' Bend in the outer section of the brass. Then sandwich TWO sheets of plastic, top and bottom. Cyano and clothes peg together. Then sand to a nice smooth finish..nice!

Thanks Fred...good thinking. Hadn't thought of that.

Hi Rich,
Alan's way would also streamline
the plane , Good :-))
It doubles the weight though,  :embarrassed:
if extra weight aft could be a problem
If JB can take the weight, that's wot eye
wood do. 8)

Then one servo for the left plane, one for the right plane, and run it all through a V Tail mixer function, "xxxxx" about with the C of G and see if you can do a barrel roll...no, tried it with my Deep Dive many years ago, silly idea as it turned out!

I can remember Dave Stevens (a mate of Bernie Wood's) doing that with a scratchbuilt submersible, it went all over the place, he gave up in the end.

Take a Dremel with a cutting wheel and cut a slit into the brass rod. Stick the planes into the slit and then glue it into position.

Or on a similar plane (pun not intended) cut the slit, and solder a thin sheet of brass as a fixer with holes like a ladle and then epoxy two thin sheets of styrene - one above and one below - the holes - to reduce weight and allow the glue to connect both styrene sheets together, profile to suit.

Thanks to my old friend Pete (subman) the dive planes are now well and truly sorted. Top and bottom rudders from a Revell Skipack...spot of filler, quick rub over with the wet n' dry...proper job.


Thanks Pete.... I owe you one.
