Finally, a speed record I've been involved in has succeeded, as you may or may not know, my quest for speed was sadly unfulfilled buy being on the Bloodhound SSC team, so I moved on to be lead mech design engineer on an electric airspeed record attempt......anyway, could could say it was a success.

She's a "sassy little thing" (quote Phil O'dell), very tricky to fly, but hey, it's done the job.

Congratulations to yourself and all those involved!

Any chance you'll be involved in Air Race E too? I've had some initial interest for involvement.

Congratulations to all the team.
I saw if flying over the house several times, looks a very sleek machine.
And when flying in formation with either the Spitfire or P51 Mustang chase aircraft also sounded rather good smile

Well done. Is there any video footage about?

Congratulations!

Much more relevant and impressive these days than an LSR attempt.

What's the range/endurance profile like?

I assume that for the timed runs it pretty much flattens the batteries in the 2 passes in opposite directions, but what sort of potential would be on offer for a light aircraft of more conventional levels of performance?

I'm a little disappointed that it's not a proper Heath-Robinson affair, it looks too much like a proper aeroplane! smile

What flight duration will it get at those sort of speeds?

There's a link at the bottom of the press release.

Probably about the same as a Supermarine S6B back in 1931.

Congrats to the team.

Why is it tricky to fly?

I had no idea what it was going to sound like, but I am surprised it sounds... just like any other prop aircraft.

Just goes to show how many loud aerodynamics are happening around propellers.

Surely not? The Schneider Trophy race was 220 miles, run flat out for the whole race, of course... one surely wouldn't burden an electric speed record breaker with enough batteries to do that, when all you need is two passes over a measured kilometre/mile?

I was thinking more of the principle rather than the exact numbers. The Schneider Trophy planes were also used to set records as well as win races.

Why do have to be such a pompous ass about it?

I was quite impressed with this until I read your comment. Now I can only see this achievement as another miserable bit of parsimony that's coming to take our fun away.

Probably for the same reason you have to be such a touchy little princess.

The LSR is a dead horse... has been for some decades, and you'd have to be a fool not to recognise that.

This record is genuinely pushing our knowledge forward in a field that is going to be extremely important.

Excellent stuff very exciting for the future, I think RR underplayed what it was capable of quite a bit which possible led to less headlines than it deserved.

Definitely a lot of Schneider about it.

Yeah, thing is, if you were to pack the amount of fuel energy that the S6B carried into something like a Cessna, you'd have a 1,000 mile range.

It would be interesting to know the comparison for this.

You can argue the relevance angle, but to dismiss the LSR bloodhound attempt as 'unimpressive' is deeply disingenuous and much more to do with projecting your self-perceived moral superiority.

My point is that climate change is going to be process of winning hearts and minds. Mocking those you perceive to be on the other side of the fence is going to do nothing but alienate and prejudice them against making the changes necessary to reduce climate-affecting emissions.

Wind your neck in.

You think, sweety?

Ultimately, Bloodhound failed to achieve anything, and if it had, it would have only have been to break a record we already held and that nobody but a handful of nerds is interested in any more - that's why it failed.

The LSR had ceased to be relevant long before climate change reached the top of the agenda, so no need to get your panties in a tangle about 'mocking the other side'.

Don't get me wrong in thinking that I am aligned to the 'other side' in any case: I have a long standing interest in the LSR and WWSR. I can be counted among the handful of nerds who have any interest for them and I'm willing to bet that I know a lot more about both than you do (almost up to Eric Mc levels of nerdism in the subject, in fact), but even I recognise that the importance of both records is now almost entirely historic. They're almost exactly as irrelevant as the piston--engined airspeed record.

In theory, at a cruise after 250ish it could fly from London to Paris

Small tail fin means it's quite active in yaw, it's a trade off, drag v stability
