Careful, you'll have STEMO wanting to run his sweaty little paws over you posting stuff like that!     

F**k off, even I draw the line somewhere

  So your standards have gone up after your bromance with Gixer?

Just wait until Mrs Bear reads this... Mrs Opti could probably learn a thing or two

Talking of 0-60,you don't need a roller coaster,how about a milk float

They use  '1ft rollout' to massage the figures, but the Tesla is still pretty quick for a milk float. But why does it need to sound like a milk float?

You want accelleration ? - Two wheels and a 1 litre 180bhp engine is whats required. 
Mmm, summers coming. I must try to resist.

Old bones and tarmac don't make a good mix. 200 BHP and less than 200 KG is more the norm these days.

That and the need to keep my licence is why I must try to resist. It ain easy after 40 years in the saddle though.

Lots of faffing beforehand, mind. FF to 1:50.

Kevin. I have to say I have never associated gliders with stomach churning acceleration.

Serenity and mindful contemplation yes. Drag strip acceleration no. :

Your Westfield must be pretty quick out of the blocks until it runs into an aerodynamic wall.

[Kevin Wood]

Well, you should try a winch launch some time. 

340 kg glider + pilot at one end of the runway, 502 ci V8 at the other.

Yes, the Westfield is "adequate", I'd say.

502 cubic inches is about eight and a bit litres by my reckoning.

At roughly what speed does a glider leave the ground using that method and how long does it take?
 

[Kevin Wood]

It's probably off the ground by 40 knots.

Watch the video:

1:58 Glider starts rolling
2:01 ASI reads 40 knots. Off the ground.
2:02 ASI reads 50 knots.
2:04 60 knots.

60 knots = 70 MPH

2:40 Launch finishes at 1300 feet - not spectacular. I suspect it's a shortish airfield. Still nearly 2000 feet per minute, though.

That's a 2 seater glass glider with 2 POB, too, so probably double the weight.

Granted, I don't know what the wind was doing that day so the glider might be climbing into a wind gradient which would enhance the indicated air speed versus ground speed. Having said that, there's significant lag on the instrument's response too, which probably cancels it.

[Lazydocker]

I have fond memories of both winch launches and the occasional "cable break" which always gave a bit of a buzz

Did all that malarkey for my annual check a couple of weeks back.. Unlike the video I wasn't camouflaged and I called the instructor things... but "Sir" wasn't one of them.
