Note the three gears on the upper, right bulkhead -- that's how I'll get three outputs from one input.

Just mentioning this by the way?

You know your gears sir....it's not so simple to get it the same as the original regarding rotation of the propellers.

This is really nice.....am I right assuming you are going to align the PS and SB output shaft in the horizontal plane and offset the central one horizontally (down) and vertically (to PS)?

Not really Zulu but its filling in the time between Zulu tasks - the new tail for the Delta III.

Much better mate......think you are infected with the “rivet counter” microbe.

Fitted the fore and aft safety lines and the rear antenna support.

Form an orderly cue... all those who have a clue to the back; those without, take charge!

That makes perfect sense. I'm really looking forward to seeing this thing and getting it installed. Can't wait.

OH!? .... explain it to me then, I don't have a clue!

These shots will demonstrate what we have in the way of the SD for your fine looking ZULU:


In the hull is a 2" diameter Lexan tube, off-hull is a 2.5" SD


See how high out of the water (in surface trim) the 2.5" cylinder is? Yuck!


Here's the 2" SD cylinder -- its top just about even with the designed waterline. This is more like it!


Ready to start 2" SD fabrication, Scott. Waiting to hear from you. Note the three gears on the upper, right bulkhead -- that's how I'll get three outputs from one input.

The single-shaft 2" motor-bulkhead to the right illustrates how your get your unit: servos and pushrods installed. Before it gets out of here it will be tested for water tightness and function. All you'll have to do is populate the SD with the usual devices and non-sense.

No problem. 2" sounds fine to me (since I know no better). Thanks for the feed back too. I'm happy that its an improvement on the last one. Slowly, slowly.

Scott,

OK, got your ZULU kit broke out and examined. First, pal -- a big improvement over your neat little ROMEO. You are on the 'fast' learning track, sir! Good job. And no significant warping of the GRP hull parts. And I love your breaking the upper and lower hull at the waterline.

Speaking of waterline ...

... A 2.5" cylinder is way too big. One-third of it will be out of the water in surface trim. So, our SD's will be of the 2" flavor. I'm currently working on a gearing that will give us the three propeller shaft outputs from one single motor. Trust me, it will work. Pictures soon.

A 6" long ballast tank, using the 2" SD cylinder -- even accounting for the displacement of the gas bottle and conduit tube and other happy horse-**** inside it -- will give us a floodable volume of six ounces. By the way, I came up with the same above waterline weights (assuming that the GRP and resin have a specific gravity close enough to 1 as to not matter) as you did. We're on the same page.

I'm cutting Lexan tomorrow -- so get back to me if you have any heart burn with this arrangement, Scott.

Damn it "might not", not "might be be". Curse these plastic fingers.

[HardRock]

Hurrah! Enjoy the moment - it might be be so wonderful after you open the package! (I think my father said that to me along time go - just after my first marriage).

(squeal of joy)

It's here! Film at Eleven!

Thanks Mate. I suspect that because of the tight internal diameter, a portion of the ballast tank will be above the design waterline - maybe up to a third. I can get by with a forward battery space of 5 inches so I'm leaning toward 5 inches for the aft space; 6 inch ballast tank; and 5 inch forward space. What do you think?

Very good. 5" X 6" X 5" it is.
