Stingray Build

Didn't they use an old tap knob for the ratemaster on the original?

I would guess that Mamas will have to make a custom master as the scale is different.

That translucent 'ratemaster' looks like an old style glass door-knob.

David, I may be missing something here, Door Knobs?

[He Who Shall Not Be Named]

Check the hardware stores for suitable door-knobs!

Today I did the fins and the conning tower, all need finishing off. tommorow I will do the periscope head and might start on the dreaded ratemaster.

Some people just have a Knack for it. Others, like me just...........watch.

I agree there... especialy when the watching is ejoyable, educational & yet suspensful all at once. :)

No trade-school or such behind you? Self-taught. You had a good teacher!

David,

Lol, again thanks David. I have been around for a few years but never really put myself in the forefront, Happy to keep a low profile lol. As for my method of building, My fave uncle (No longer with us) used to say. "You visualise something and then it springs from your hands". I guess thats got to be true. Oh plus the fact I'm not a patient guy so I try to work fast. I definitely like to throw it at the wall, lol.

Your trick of establishing the inner and outer contour points on the stern is an example of simple, functional, lay-out work. You make use of rigid materials (the plastic card) for the basic structure, and leave it to the formable filler to fill in the blanks. The basic means of dictating final form of tapers and compound curves to a complicated sub-assembly. Even using the existing stern as a guide. No flubbing around; no mis-steps; and FAST.

You strike me as being both an intuitive throw-it-at-the-wall-and-see-what-sticks sort of guy; but also one well versed in the disciplines of pattern making (plan interpretation, lay-out, materials selection and use).

Who the hell are you, and where have you been hiding all these decades?!....

Thanks David. Done a bit more, Cabin Primered but still needs fine work done and tail mated to the back end.

[He Who Shall Not Be Named]

Damn! ... this is good stuff!

Made a start on the cabin and tail section yesterday and will finish them up this afternoon. Same method on the cabin as the main hull but I'm using plastic bumper (fender) filler on the tail. It retains a greater degree of flexibility when set.

Done the tweaking and happy, just a few blemishes to rub out and then the cabin.

Lol, same way I did with the smaller one I think, that one had a graupner mini jet with vectoring rudder and the side fins were on 2 mini servos and mixed thru my transmitter (Elevons). It worked really well, to the point that it flipped over in the water when I turned to fast. In this one I want to use the same jet as in the Skydiver ones, going right thru the ratemaster which I will attempt to make spin as well. I have an idea how to do that, perhaps a ring spur gear on a small pinion. but thats for later.
BTW the small one now resides with my Brother as he pesuaded me to swop it for a 1/5 scale RC petrol (GAS) car. As I had another one in the works I agreed to it (thats the White shell you see in the early build pics)
