Asymmetric Stall (for uncravating)

 

Slow down symmetrically by at least 30 cm (after the contact point) and wait to stabilize the pendulum movements.

For an asymmetric stall to the right:

Weight shift on the left.

Look at your right wingtip.

Right arm: raise the elbow above the hand (to have strength).

Bring the right hand down sharply! Quickly and completely: arm extended under the buttocks while watching the wing.

During this time: maintain counter weight shift and brake on the left to avoid turning.

At the moment of the asymmetric stall:

  • the wing deforms (wingtip warp backwards)
  • the right brake softens
  • you feel a sideslip on the yaw axis

And also:

  • the wing deflates
  • you feel a slight imbalance in the harness

 

Immediately release both brakes quickly and completely: “hands up!”

Let the wing begin its dive (aerodynamic dive)…

Make a “short timed brake input” type catch: 50 cm quickly and not maintained.

 

The goal is not to deviate from your heading (less than 45° change of heading).
The more it turns, the stronger the dive will be, the more you’ll need to catch strongly.
 
Be careful not to accidentally unhook your reserve handle!
