The Alien is a fully moulded HLG flying wing from the team Christophe Bourdon / Anton Ovcharenko (OA composites). The idea is to propose a flying wing with wide speed range, high manoeuvrability, but still with great ability to thermal soar.
The Alien can be flown at the slope or on a flat field with discuss launch. It can be ballasted to fly in higher wind, especially at the slope, and can be even used to do some light dynamic soaring.
Specifications are the following:
- Wing span: 1.20 m
- Wing area: 17.1 dm2
- Length: 62 cm
- Flying weight from: 240 g
- Wing loading: 14 g/dm
- Aspect ratio: 8.4
- Wing airfoil: 6% proprietary
- Dihedral: 2.5º
- Centre of Gravity: 29.5-30.5 mm from wing leading edge
- Controls: Elevons, rudder (3 servos)

Wonderful video Pierre! This flying site is impressive, to say the least. Lovely model and great flying :)

I like how the tail on this plane initially caused me to question what was going on. But where’s the eleva.. oh, it’s a wing. :)

Can you let me know at which settings you've had the "flaps" during this flight? Tks

The wing remains in section for trimmed flight. Any camber or reflex effects the pitch, hence the term 'elevons' for the control surfaces on the wing.

Hello Pierre, I'm living in the same area than you (close to Grenoble) and learning (again, last time was in the 90's) how to fly RC gliders at 45. I discovered the Alien with this video a year ago. Having recently flown several small foam gliders for training, then Dream Flight Alula, then I got to try a 2 axis1m F3K. But this F3K seems really optimized for thermal on the flat, on the slope I think it will be limited to very "soft" wind conditions. The problem I have when I go hiking is that I have to carry several models of different sizes, because it is still difficult for me to anticipate the wind conditions. So I'm looking for a model that could do both F3K and slope, even with stronger winds ~30-35 kph. In your opinion, is the Alien suitable for a "beginner" like me that knows the basics, but has a lot to learn ? With 250gr and 15gr/dm2 wing load, can it be a rather good F3K on the flat ? Or F3K is just the icing on the cake, for a wing designed primarily for slope ? The other options I have found (for beginner and affordable) are the 1m Hawk from OA composites, or the Stiletto Lift, 1m20 from Jim-Aero, with split-wings. Ps: as a long time hiker, when I've been looking for slopes I ended in the same spots than you : Connest, Pierre Percée, Sénépy, Glandon, Beaumont... I also know the Puy de Manse ;-)

Bonjour Florian, le stiletto ou le MicroMax devraient mieux répondre à tes critéres je pense. Si tu peux trouver un micromax avec aile en 2 pieces se serait encore mieux.

@@Planet-Soaring Merci pour la réponse en Français dans le texte 😉 A priori le Micromax n'est pas un F3K, mais en effet j'ai vu les vidéos de Pierre Meunier et la tienne à la pierre percée ; ça me semble être un bon compromis pour du vol de pente, cela dit avec 90gr de ballast pour 5-10 m/s de vent, et au-delà ?
