Duane,

When I am neutral and positive and do not want to prove anything I can warn you,
Be carefull with you Taurus II because I think the centre section (of the fuselage) of your plane can be from the oldest taurus on Earth.

When that is not thrue, then Ed did use the design of my Taurus, of the crate to design yours, but!!!

There are too many details the first point is true.

Again with the tank, Ed did all to get the optimum of fuel to air ratio and less influences of G- forces, so did look to the controlliners, just I do,
But I use a fuel pressure controller and tank pressure controller, that's better for my Enya 60 4C and I can make them.
BTW same story about air-speed. On the point Ed did stop by not having the controllers I continue.

About the tank, its has a design background probably of a control liner tank, only Ed did use it 90 degrees turned.
He could not use pressurized tanks, they did not have mufflers and he did want to fly inverted and loopings.
The air input is in the centre of the tank that's why the pressure above the fuel is - p = h x y ,
controlliners use this (Bernoulli) so you get no extra pressure of the g-forces during control line flying see picture 2.
For RC this solution is not optimal but is is the best they could get I think. And filling the tank, that's the trick!
But yes, a ST 56 with a tank of 180 cc, you know the tricks!

See picture 1. I already did make it yesterday for you to show and with the K & B, no Veco no ST.
