ULTRALIGHT CONCEPT SV4-RS Stampe

The Stampe SV4-RS is the ultralight replica of the famous Vertongen Stampe SV-4b from the 1930s.

Ever since I installed an E-Props on my SV-4 Stampe, it feels like the plane wants to do loops on its own! It climbs like a mountain goat, sips fuel like a moped, and turns heads on the ramp. Even my wife thinks it looks sexier now (the plane, not me). In short: lightweight, efficient, and built by folks who clearly love what they do. Highly recommended – just don’t close your eyes while flying !

DURANDAL-2
Did my first flight today, very satisfying.
I adjusted to 16,7 degree, this gave me 5550 RPM and 125 km/h in straight flight. RPM during climb is roughly the same as in straight flight.
The sound is very good, a lot lower than with the propeller of firewood I had before.
