Never seen anything like it since.

There used to be a model aircraft show at Elvington airfield every year in the nineties. The star of the show was always the extremely noisy pulse/ram jet (similar type of engine to those used in the German V1's).
They used to climb so high that they were out of sight, before diving back down and flying along the runway at high speed (if I remember correctly it was claimed that they reached 200mph).
I think I'm right in saying that once the engine is fired up it can't be controlled, it just keeps going until the fuel runs out.
The controllers couldn't afford to take there eyes off them for a second......blink and you've lost it
Maximum respect to those who flew them.

Hi all

Yes some models are amazing, like the Boeing 747 with a 22ft wingspan and 4 perfect mini (or not so in this case) jet engines, the guy had to build a special trailer to take it to shows, and 200mph for a model plane is nothing nowdays, the ones without engines will do near 400mph dont believe me? have a look at this, remember NO ENGINES just a slope soarer and clever use and massive knowledge of the air flow over a hill http://www.youtube.com/watch?v=WaQB16Za ... re=related this is what got me into slope soaring

Fantastic

thats what i thought when i first saw it, you always think of a 'glider' being some slow old thing that falls to the floor 20ft in front of you but in model form at least they are actualy better than the powered ones, but then stuff like this is just fantastic too www.youtube.com/watch?v=fbITzCI2AU0

Re. the 400mph glider.......

how?
How can it reach such speeds?
How can they keep track of it?
How do they stop the wings falling off?
Amazing


Re. the B52..........

That's not really a model, it's big enough to carry a pilot, it should be classed as an aircraft . Wonder if they have to inform the CAA......
Very impressive though. Does it actually have eight turbine engines? Sounds nice.

Hi Paul re the glider

they use the turbulent air over the back and top of the slope along with witchcraft i believe
Drugs?
clever design with carbon fibre i believe

re the B52

i know you have to have an A and B class model aviation license (no really) to fly at shows and a giant scale license to fly one of the monsters, it is big isnt it. Some are just increadible and your right about the sound, i would have thought the sort of bloke that built it wouldnt skimp on the turbines tbh

Do you realise it's almost 10 years now since the demise of the late great SRN4s

That's right Ken, and this hovercraft 'enthusiast' never got round to going on one

I never went on Concorde either and now that's gone too

I never imagined we would take such big technological steps backwards

.

Shame on you

I clocked up lot's of miles on the SRN4s, you can still see them, but alas not working anymore, they're at the Hovercraft museum Lee on Solent.
Concorde, never actually flew on it, but have been on several on the ground
QE2, yes I've sailed on that a few times, once sat chatting with a fellow XMer on board

What do they all have in common?

Model aircraft, only once! I built (with help) a keil kraft kit of a rubber band powered aeroplane 36" wing span from memory, it only flew once and was seriously damaged on landing, so I vowed never again

What do they all have in common?

Great machines lost forever although ive heard rumours the QE2 is coming home? ive been onboard concorde at that air museum on or near the A303? i was surprised how small it was both inside and out, but it is a beuitiful piece of engineering.......

hi Ken,

I was always going to take a trip across the channel by hovercraft. And take the Concorde trip to New York and return on the QE2...........one day .
I just waited too long..........and now it's too late

I've seen the SRN4's at the museum, one of them is open to the public on show days, so I have actually been on one........unfortunately it didn't go anywhere.
Sadly, it doesn't look like they'll ever move under their own power again. The current owner bought them for the engines, to use in his vintage Vosper power boat.

I never missed an opportunity to see Concorde if I was near Heathrow and on the few occasions it came to L&B airport.
Here's a reminder..............

um, the model B52 bomber does have eight turbines, but not anymore, tbh this vid reminds me of many of my early attempts , poor bloke
