Now that may not be a bad idea, and it would be pretty cool to build a RC
plane to go on top too! Dang Dan now I have to build another toy!!!!! My
wife is gonna shoot me for sure!
Seriously , that is not a bad idea, may just do that. Will check out the
math stuff first. If it befuddles me to bad I may have to resort to a plan
B, or Plan Dan!

Hee Hee,
No simple answer huh? Thanks guys, I looked more on the web late last
night and I do think I will have to make the shapes into smaller
measureable shapes and add the totals. I do think figuring up something
before you actually build it is alot cheaper,...you don't have to build
it but once. Well we all hope anyway!
Also planning to build a set of floats and that's where the volume
formulas really get funky. I would sure hate to spend a grand just to
fill it with water and say, well not right can't use it. Heck my old lady
would kill me if I wasted 200 bucks on a ruined gas tank! HAHA
It won't be to bad figuring it all up "cutting it into basic shapes" ,
just will take some time. For the gas tank, it will be in a VP-1. I am
welding aluminum instead of using the fiberglass. An old high school
buddy, certified nuclear welder is going to weld it up for me. So I need
to send him a drawing of it, thus the need for getting it right. That
math stuff is pretty cool when you can remember the formulas ain't it?
So for the gas tank, I just wanted to see how much fuel a aluminum tank
would hold with alittle mod. But the floats , I definitely have to know
the volumes of each compartment before I even think of starting the build
there.

Nothing says you have to build a full size model. Make a fiberglass model
at 1/8 to 1/4 the size you SWAG, fill it with water and measure it out.
You can now scale as needed mathematically.

Don't forget to take into consideration material thickness, baffle
thickness etc as you plan.
