Ultra-Batics or UltraBatics is short for “Ultralight Slope Aerobatics” and refers to 3 or 4 axis aerobatic gliders that are ultra-lightweight, ultra-maneuverable, and ultra-durable. Hence, UltraBatic.
The UltraBatics movement started here in Santa Barbara, California in the summer of 2011, and is now spreading around the world. UltraBatics is the product of collaboration between “Swiss Peter” Richner, Dawson Henderson of Flagstaff, Arizona and myself Steve “Surfimp” Lange.
Combining ultralight building techniques perfected by Peter with my Le Fish aerobatics glider design and Dawson’s innovative Henderson Pulley, we were able to create ultralight versions of the plane that were less than 1/2 the normal weight, allowing a radically new style of extremely close-in, low altitude flying in very light lift. These planes are fully aerobatic in as little as 6-8mph at a decent slope, but can also fly in 20-25mph and thermal, too.
UltraBatics gliders – “UItraBats” – are generally constructed from EPP and/or Depron foam, are covered in lightweight yet very durable laminating film, use minimal carbon fiber spars for reinforcement, and generally have wingloadings in the 4 – 6 oz/sq.ft. (12-20 g/dm^2) range. Some of the most radical examples employ Madslide-inspired horizontal stabilizers, controlled by Henderson Pulleys, which are capable of 180° rotation. This allows them to do radical filp maneuvers in the style invented by Benoit Paysant-Le Roux.
UltraBatics takes inspiration from three main sources:
1. The Dream-Flight Alula and Weasel
2. The Madslide aerobatics glider of Benoit Paysant-Le Roux of France
3. The French VTPR (“voltige tres pres du relief” aka “aerobatics very close to the ground”) flying style
The intention of UltraBatics is to explore new possibilites in slope aerobatics. We are limited only by what we can imagine.
Another new design from Justin “JGAF” Gafford, which he’s calling the “No Name Plane” for the time being. Check out the rolling circle at 0:21 – really nice! Looks like another smooth flying ultrabat
First time back flying in 10+ months… feels good, man!
Maiden flight of my new Buzz Evo by JGAF’s Custom Aerobats. Frequent visitors to this site will know of Justin’s Buzz design. I really like this new Evo version with longer tailboom, it really flies great. Super tight and fast flips, good knife edge, smooth rolls, and great light lift performance. Really a bitchin’ plane!!
Dawson got some nice weather out in Arizona and got his Buzz Evolution up for a fun flight. Enjoy some smoothness!!
FINALLY!! I was very stoked when I saw this – an ARF ultrabat, how cool!! It’s the new Vagabond 1500 aerobatics glider from Hacker-Model.eu. I came across this very exciting new model on the VTPR and Slope Aerobatics Facebook group earlier today.
It’s clearly inspired in no small part by Le Fish and to my eye they’ve done a good job of it – I especially LOVE the canopy It’s built from EPP, has a 1500mm (59″) wingspan, is 975mm (38.4″) long and weighs 400g (14oz) and up… with what appears to be a fully functional Madslide -style stabilizer, direct from factory. Those specs are all spot-on for a very fun VTPR / ultrabatics / conventional aerobatics glider with great light lift performance.
The Vagabond 1500 product page also makes mention of a “foil” covering, which – hopefully – provides some kind of stiffness and durability improvement compared to the raw foam of the Telink Multifun.
I’m guessing that even if it needs a few mods out of box (and who knows, maybe it’s good to go straight away), this is going to be one of the fastest and most accessible ways to get into ultrabatic flying out there. I’m soooo stoked about it! Great job Hacker – thanks for serving our small segment of the hobby!!

JGAF at the sticks of his 36″ Mini-Buzz at Dave’s Beach in 15mph wind. Rockin’!
Justin “JGAF” Gafford and his new 36″ wingspan Mini-Buzz flying in some 25mph+ conditions at Mt. Laguna. The plane handles the conditions with no problem – check the awesome flatspin at around 2:00min!
Dawson Henderson has recently gotten a Buzz Evo by Justin “JGAF” Gafford and had it out for its first flights on a chilly winter day at Mormon Lake Overlook. He digs it!
