Really nice video produced by Noisy Skies of France. When P-A told me he was going to visit, I was stoked to host him. The result is really beautiful, and I think captures the Ellwood flying experience in a nutshell. Super cool
I've been using PicaSim (and SSS prior to that) for over a decade now and it continues to get better and better.
Its modeling of slope soaring is second to none, in my opinion equal to Aerofly and vastly superior than RealFlight and Phoenix (both of which completely ignore gliders for all intents and purposes).
Although the graphics are not as snazzy, the flight modeling is excellent and Danny Chapman, the developer of PicaSim, works very closely with experienced pilots to get things just right (ask me how I know )
In fact the aerodynamic simulation has gotten so good I am able to successfully practice "Madflight", a style of slope aerobatics wherein the elevator (and sometimes rudder) is capable of 180 degree rotation, allowing a Lomcevak-like flip around the pitch axis.
Here is a quick video I did showing how to replicate a classic move by Benoit Paysant-Le Roux with his Madslide glider.
Bottom line: PicaSim is the best simulator for those interested in slope soaring and especially hardcore slope aerobatics practice, hands down.
When I'm not flying my Le Fish down at the beach, I enjoy flying my Wasabi and Voltij up in the mountains. Getting video of the latter is difficult unless I've got someone along to film, but I tried an experiment - inspired by Ian "Daemon" Frechette - setting my GoPro Hero2 on "Narrow" Field of View.
I'm not totally stoked on the results - we just have to fly too far away up there for this method to work - but it's better than nothing, and considering it's been six years (!!) since my last precision video I decided to share.
Dawson Henderson and I have been collaborating on a wiki project meant to help support all the Le Fish builders out there - Le Fishipedia
It's meant to be a one-stop shop where new builders can learn about Le Fish, get guidance on what style/weight of build will best suit them, etc. Basically we're trying to help people avoid having to wade through thousands of pages of forum posts to find this important info. It's still a work in progress... it always will be

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 myself Steve “Surfimp” Lange, “Swiss Peter” Richner, and Dawson Henderson of Flagstaff, Arizona.
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.
