70 kg 31:1 glider is here to stay?

Of course here is the latest in FL sailplanes - not
even in production yet...

For soaring, this is it.
New racing class?
Why fly fast when you can fly slower.
What's a rush anyway?
Race slower, cover less ground, easier retrieve.
Stalls at 31.4 km/h

You've got to take a look at the bungee launch vidro they;ve got.

For this, and any light sailplane, this is 1000% better than foot launch.
Just take 20ft of linoleum and a bungee to the launch site and you're off.

Love that acceleration.

Trike (just) gear and low stall speed leaves little chance of a wing drop.

.... not to mention the car, trailer and time to get the glider up the
hill to the launch site. vbg

Look at the flexing on the side of the fuselage during the
acceleration. Scary.

You still need those things if you foot launch.

Shouldn't be - it's just a lightweight fairing, not structural. The tail
on my ASH 26 E oscillates side to side when the engine is at full
throttle, causing some concern in bystanders unfamiliar with gliders,
but the tail hasn't fallen off any of them yet! Appearances can be
deceiving.

If you think that looks scary, take a look at the fuselage skin of this
A-3D.

I think the fuselage is metal tube structure with a FRP or just P shell around
it. Given that, all the loads are taken by the metal tube structure; the shell
is for aerodynamic and cosmetic reasons.
