No, lower centre of gravity (which a heavier fuel will give you) will result in more stability. Could also be that the parafin/kerosene gives more energy per kg burned than hydrogen. This is important when you need to overcome air resistance and gravity. It would also help that the heaviest part is dumped first.

Doh! Should have guessed. Although the stability control system should be able to compensate for that.

No. Go on then...

Fantastic!

Top job.

Light blue touch paper and retire

These are J-2's (second stage) And so is this (third stage). The first stage used an F-1 motor (F-1)

Perhaps the nozzles are hiding columns inside them which support the weight of the unfuelled vehicle?

Rich is right. I had the same problem. Just check to see whether the breather is kinked under the mudguard.

When hopping I have the front wheel straight but on balance I have it at 45 deg. As I start to hop I straighten it. Don't worry about losing balance when you start hopping. Most of us had that problem..

Perhaps not the nozzles but where they mate with the rocket.

The force MUST be transmitted through those components. The gimbal actuators will only transmit a fraction of the vertical force. Reminds me of the old story. If a fly is flying in an aeroplane that is itself flying does the weight of the aeroplane include the weight of the fly? (Yes, the force that keeps the fly aloft is applied to the floor of the aeroplane adding to the weight. The key here is the word weight)

It was only after I posted and looked at the vid again I realised that you were talking about the bell distorting during startup.

I'm not sure about this Copey. I've watched the phenomena with interest many times and I suspect it's a resonance. It may be related to the dancing diamonds you see when an afterburner is in full stride.

That's not bending. The nozzles are on a gimble. This is how they balance and steer the shuttle. Why don't the nozzles melt? Well they're cooled. The LOX is fed thru' them prior to being mixed with the fuel. This was Goddards big breakthrough.

Very clever Wayne

I suspect that many of you, like me, are closet moon race fans. I can't get enough of the history of, arguably, the greatest feat of engineering in history. If you are have a look here. It's pure gold, all the stuff they gloss over in "from the earth to the moon": Saturn quarterly reports

Have a search on these forums and all will be revealed.

Yup, that's the one Woody. The only problem I had with the clutch was that it would slip between sections. At that time sections were changing and the new sections favoured bikes with a ight turning radius and less flywheel. Exactly the opposite to the the 349/4.

I had the first and the last model 349. Of the first, the less said the better. The last was a much better bike BUT it had been eclipsed by the Fantics. Put simply riding a 349 against a Fantic 240 was like going to a gun fight armed with a knife.

Ah, thought that might be the case. Thanks Dabster. Looking at that 'arm, do they have problems with the 'arm cracking just forward of the shock mounting bracket? Like they did with the 199?

Jasper, if you have a look at: OzVMX, there's a quite a few guys who have 414's who'll be able to help. Even some from South Africa!

What's with the s/arm? It's a round not square section.

The factory boys seem to be allowed to do the Spanish multi-day events like Cingles and Santigosa but not the SSDT?
