The guy purportedly built the engines from scratch too.
I want one.

I used to watch the real one's all the time. Awesome plane

awasome some people are very clever !!!!

Hahaha
Know it all (harsh guess) starts backing away at 40 secs, and does one altogether at 50 secs........

Quality.
I've been showing my <2 year old model planes and heli's for the last week as he's obsessed with turning everything in the house into a rocket or plane at the moment.
I've been watching some cool stuff;-

Had a work colleague who was posted to Beale AFB, (home of the SR71).
Apparently, the fuel tanks were only 'sealed' at supersonic speeds, when everything expanded due to kinetic heating. (A lot of titanium was used in the build).
When parked out in dispersal, the aircraft had huge drip-trays located underneath, because the fuel system leaked like a seive.

Puts Concorde in perspective. Mach2, up to 120 passengers, wear a suit and drink your gin&tonic. 3 aircrew
SR71, 2 pilots in space suits. Mach3.

That looks a bugger to land!

Make a bottle rocket!

I've got an awesome one. It's a 3l bottle of coke with a 2 litre bottle glued and duck taped to the top, then another 2l bottle slid and taped on for lengthening it. I put fins on the side to keep it flying true made of an estate agents sign, and added a m10 nut and bolt through the top cap for weight. With the 3ltr bottle strapped with tape it can take 100psi.

I made a launch pad from a 2ft square bit of timber with stud bars holding a plate which it presses onto, that has a bit of nylon, an o rind and a schraeder valve in the bottom of. A couple of bits of angle iron then and a car radio removal key is the launch pin.

So you put the bottle on the pad, adjust if needs be, lock it in with the radio key with string on it and secure the thing to the floor using tent pegs. Then attach your foot pump, give it 100psi, run away and pull the string.

It makes a sound like a gun being shot and goes so high it's unreal, I've found 2l of water to be the optimum in terms of flight time!

I taped a mobile in it once to capture in flight video, not recommended........

All that needs is afterburner glow!

wander if it gets the blue cones...

If you ever get a chance, try reading the book called "Sled Driver" - it's written by a SR-71 pilot and gives a real insight to these aircraft. Apparently they were absolute bar-stewards to fly! Imagine flying at Mach 3 when all of a sudden your helmet gets slammed into the canopy as one of the engines stalls... the pilot had to keep adjusting the cone in the intakes to make sure the engine ran properly.

Lots of humour in the book, too...

Amazon linky (bit expensive there, though).

Oh - before I forget - nice model!

Don't forget that it was Mach3 at 80000ft!

I'm hoping to leave the nerdy area of rc planes and helis and move into the slightly less nerdy area of kit car building in a few months xD

No, it was 100,000ft. However at 60-65,000ft, the G&T was with ice 'n' a slice.
