Ultrabatics: ultra light, ultra maneuverable, ultra durable gliders that enable a new level of unlimited aerobatic performance in slope soaring.
The glider is Le Fish, an open source design developed by Steve ’Surfimp’ Lange (me) in the USA with lots of inspiration from the French VTPR tradition (voltige très près du relief / “aerobatics very close to the ground“) as well as the tremendously influential Madslide of Benoit Paysant-Le Roux aka BPLR.
