[QUOTE=He Who Shall Not Be Named;n188920]So after watching the videos you posted, I have my first questions.
During the video of the 1/128 Moebius kit in the big pool, I believe you said you thought you should add some bow planes to the front of the Seaview as she tends to dive with that big wing in the front.
Did you do that? If so, was it a cut of the wing and how wide did you go?
That's something I will have to plan for in modifying my Ken Lane files.
Also, I think it might be best if I create a new topic based solely on the Ken Lane Seaview so as not to disrupt this forum.

[QUOTE=TAGood827;n188961]I've assembled four of these wonderful Mobius kits, but only one was outfitted with practical 'bow planes'. The other three -- assemble and profiting from lessons learned on the first, bow plane equipped unit --only required practical INDEPENDANT (and that is an important distinction) stern planes and fairwater planes. The practical bow planes turned out to be an ugly and redundant means of controlling the submarines pitch angle. Let let the following illustrations make my argument:
That first SEAVIEW was totally uncontrollable in pitch once achieved submerged trim; any advance of the throttle and the shovel-bow pushed the nose down and control could not be regained without going all-back-MF'r. I retrofitted the bow planes, and only with that rather ugly arrangement (see below picture) could I control the boats pitch angle. The stern planes and bow planes were mechanically linked together and worked in unison to rotate the boat about the pitch axis
Ellie and I produced an entire range of fittings kits for this subject. Here you see the bow planes, control horns and a portion of the stern plane-bow plane push rods.
Though the retro-fit bow planes continued the compound curved lives at the tips of the 'manta fins', once they assumed any angle the entire aesthetics of the submarine were ruined!
And here is the linkage that ran from the bow planes to the stern planes. As to the dimensions of the bow planes -- those were driven by the engraved outline represented on the kit parts by deeply engraved lines. Just follow the lines and you have the shape of the bow planes.
The stern portion of the bow-stern plane linkage.
Through extensive testing, evaluation, and experiment I came up with the fix: pre-setting the stern planes at a slight 'rise' angle and incorporation of a fixed stator van in the bottom of the nozzle to also produce a pitch-up moment whenever the pump-jets were pushing water. These two steps eliminated the need for the bow planes.
I have no problem sharing my thread -- the objective is to interact with you guy's, not to spout off without challenge from on high.

I’ve never seen anyone perfect parts of the boat that will never be seen by anyone as you do. For some reason I’m the same way. I take pride in my limber holes being correct and square. It’s kind of weird, isn’t it? I would even say anal. I’m the same way with ham radio equipment. If I see a used piece of gear, and it’s got one smudge on it, I won’t buy it.Of the approximately 40,000 men who served on U-boats in WWII, it is estimated that around 28,000 to 30,000 lost their lives.Comment

What kind of model are you performing repairs on in the last pictures? Victor III/Akula semiscale?Comment

I don’t think I’ve ever seen you use a gloss color. Also, that particular shade is a new one on me. Excellent build.Of the approximately 40,000 men who served on U-boats in WWII, it is estimated that around 28,000 to 30,000 lost their lives.Comment
