Why does the shuttle throttle on ascent?

_Tail tank_?! Oh, I've got to see a cutaway of this! :-)
Apparently, some Soviet jets used fuel tanks in the vertical fin.
The Monogram (now it's Revell after the two companies merged)
transparent model of the P-51D has the fuselage fuel tank in it:

The really amazing model was the transparent Monogram 1/24th scale Bell
UH-1 "Huey" helicopter.
It took forever to spin up to full speed, but God help you if that main
rotor ever hit you at full RPM. :-D

Not literally in the tail, if (dim) memory serves, but it was called that
because it was in the aft fuselage.

I didn't have a transparent UH-1, but the one I did their regular UH-1 model
(at least I think it was a Monogram). I modified so that it would spin the
top rotor via an electric motor and a couple of LEGO gears. Luckily on this
model the fuselage cover easily slid on and off, so everything was hidden.
Boy that thing would spin that main rotor *fast*. ;-)

Unfortunately, my painting skills weren't that great at the time, so the
overall appearance was rather shabby and like almost all of my (poorly
built) models from that era, it was likely destroyed by fire crackers.

We loaded pellets into our Crossman airguns, but the principle was the
same. :-)

My brother and I used to sink battleship models that way. Once surfaced and
dried out again, a piece of paper coated with glue made it seaworthy again.
We had many models that started with styrene and ended with paper mache.

We also used to use bags full of those green plastic army men as BB
targets. I will never forget my favorite lucky shot. You remember
that guy who was standing up, arm hauled back with grenade in hand
ready to throw? I once managed to hit one of those guys dead-center in
the head, causing the plastic to extrude into a perfectly circular ring
around the guy's brand-new copper face. :-D

There is a group of ship modelers who build radio controlled warships
out of balsa wood, plywood, and Silkspan fabric that are themselves
equipped with remote control BB guns and go out sailing around sinking
each other.
The radio gear is kept in a BB protected waterproof container so that
it doesn't get damaged when the ship goes down.

This must be a _lot_ of fun! :-)

Yes, they also did a non-transparent version, minus some of the inner
framework parts.

I've seen some pretty shabby looking real ones over the years.
Monogram also did a 1/48 scale Huey and Huey Cobra.
Revell did a 1/32 scale Huey ( in fact they did at least two versions of
it) in 1/32 scale, and also did a 1/32 scale Cobra.
These all were around at the time of the Vietnam War, so Hueys were well
known.

Iirc, this was the 'copter with what my Dad called the "Jesus Nut", that
one nut that allegedly held the whole craft together and, when hit by
enemy fire, gave all aboard just enough time to yell "Oh, JESUS!".
