I think the builder did a lot of fine work but fell short by not replicating the articulated nose.

Hopefully itís in the pipeline?

That is freaking assume! Almost as noisy as the real thing too
I wonder what he used for engines? That must have cost him a fortune - no such thing as cheap jet engines - even then they are small.

JetCat P-series microturbojets run from $2500-ish (5.5 ftlbs P20-SX model) to $12000 (89 ftlbs - P400-PRO model, as used (x4) by Yves "Jetman" Rossy for his rigid-wing flying suit).

I'd assume this Concorde uses something within a similar range (also x4). 150Kg airframe weight - you of all people can estimate the thrust selection needed (certainly better then I )

No, not cheap if you want 4 - but still less than a Piper Cub.

For the similarly uneducated -
"Lick my ass, that's incredible"

Amazing tribute to the most beautiful aircraft ever built.

I don't own this space under my name. I should have leased it while I still could

Very impressive!

I am amazed at how well it handles. The aerodynamic qualities of the S-Delta are unusual to say the least, and I would have guessed not directly scaleable. I wonder if there was some degree of fly-by-wire added to enhance stability?

Thrust is measured in lbs. No feet involved.

Well kind of in lbs - this piece of wiki should make it all clear - as MUD
"The pound of force or pound-force (symbol: lbf[1], sometimes lbf,[2]) is a unit of force or weight used in some systems of measurement including English Engineering units
[a] and the Foot–pound–second system.[3] Pound-force should not be confused with foot-pound, a unit of energy, or pound-foot, a unit of torque, that may be written as "lbf⋅ft"; nor should these be confused with pound-mass (symbol: lb), often simply called pound, which is a unit of mass."

It like a Monty Python sketch - I recommend going metric on this one if you want to get closer to what is going on. Indeed the manufacturers use the SI (International System of Units)unit of force (Newton) as their primary statement of the engines capacity to do something useful..

JetCat P20-SX micro turbine for small model jets with a thrust of 24 Newton or 2,4 kg
JetCat P20-SX Micro Turbine with 24 Newton ,5,25 Lbs ( 2,4 Kg) Thrust.

What this means is that the engine above (P20-SX) will just barely hold a 5.25lb bag of potatoes off the ground, using a suitable system of frictionless bearings, pulley and weightless cable so that the engine is not supporting itself or its fuel etc.

There were some cool ones flying at Brunties Jets do, including a Frightning with a ring of lights in both jetpipes that just looked like lit burners, sadly after lift off and banking over the trees that was the last we saw of it, the two guys standing out of the field for a while in shock before departing in a transit to try and find it, I do hope they did and it wasn't badly damaged as it was a superb model.

I see Concorde is 1/6th scale, to put that in perspective, action man figures are 1/6th.

and the reheat! Wonder if it can be built into those mini turbines

A nice bit of heat haze in the head on long shots though

Shifty six used to lose the real ones regularly too. Probably ran out of fuel. 😁
