Only 3 MBTs in the bow! So, only 6 MBT vents. The rest were aft end, behind the Engine Room, in the tail cone.

Thanks to David and Sam for their help I'm ready to start a model of USS Tucson SSN 770. I'll do this in a separate thread.

Next Update,

Just soldered up a prop linkage from the shaft on the hull to our Most Esteemed Leader's WTC. As you can see, the WTC is presently positioned aft so that the Center of the Ballast tank is ~1 inch forward of the center of the boat (lengthwise). Thanks Admiral Greenman.

With no battery installed, the CG is somewhere near the aft 1/3 of the boat.

I'm planning on a 6 Volt, 14 AH Werker Gel cell, unless someone wishes to correct the abhorrent error of my ways. This cell weighs ~6.1 lbs, which should drive the dry CG into the forward 1/3 of the boat.

Is there a rule of thumb for where the CG should be in relation to the Center of the Ballast tank, which is positioned as stated above?

CG at the longitudinal center (or thereabouts) of the ballast tank.

Here is a file I pulled of the web but it looks strange. I'm trying to form the forward and after hulls but I can't confirm the dimensions. Can anyone point me in the right direction?

I can do more than help. Send me your address and I'll fix you up.

Tom,
I don't think I sent the plans to you but if you are able to loan me yours I will return them after I get the information I need.
Thanks

When we moved to Arizona I gave up my Greg Sharpe LA plans along with several others. Now I'm sorry I did that. The LA plans I found online are suspect. Can someone tell me the following dimensions?
a. Length of bow to fwd parallel mid-body hull
b. Length of parallel mid-body hull
c.Length of after end mid-body to fwd end of prop.

This will help as I start another model using 3-1/2 inch PVC pipe as my parallel hull.

Will,
Did I get those plans from you? If so, I will dig them up and send them to you.
peace,

I love it when a 9 year old build comes back to life.

I bought it from Prop Shop UK. The model number is....MS/28/7/RH/BR. https://www.prop-shop.co.uk/

I ordered a prop with a 20mm hub diameter, but I believe if you email them, they also have one in a 15mm hub diameter.

Hope this helps.

Good day sir, I’m throwing this question out all over the place hoping I get an answer sooner than later. What propeller are you using for your LA? Do you have a link to the purchase site by chance?

Thank you for saving me from 6 lbs of a battery, I would have needed a lighter than air substitute to trim the boat!

Right now, the CG is within +/- 0.5" of the center of the ballast tank, which is 1" forward of the geometric center of the boat.

And, the boat is wet.....
