Excalibur 2.0
The Excalibur 2.0 is an acrobatic glider designed for "VTPR", voltige très près du relief
(literally "aerobatics very close to the ground"). It was designed by Eric Poulain and Rémi
Le Besque, since a good video is worth a 1000 words here is a video where they demonstrate the
capabilities of this glider http://aero35.free.fr/Videos/Menez2.wmv (60mo)
Specifications:
Wingspan: 2.60m (102”)
Airfoil: SB 96 V and SB 96 VS
Surface: 52dm²
Weight: 1.8 to 2kg
The secret to a VTPR glider is to keep it as light as possible, it is on that basis that Rémi
made what he calls the Excalibur light, which weighs 1.6kg that might not seem much lighter than
the regular version but shaving 200g off an already built to the minimum weight glider is quite
a challenge. The main difference is the use of carbon, the 160g/m² fiberglass reinforcements in
the wing where replaced with 85g/m² carbon fiber and the already thin fuse in the regular version
now only has 1 layer of 160g/m² plus carbon strips of carbon tow.
The down side of this glider is that it is not produced and it is very hard to get your hands on one.
I luckily was able to buy (you may say pry) Rémis used Excalibur light. Here are some pics:
