David von Oheimb's Photo Gallery: Stratus 1600, Oct 2005

Radio controlled high wing electric powered thermal glider by Kyosho, V-tail version.
Wingspan: 1600mm, Length: 1010mm, Wing Area: 28dm², Weight: 700g with electric drive.
Drive: Graupner Speed Gear 400 7.2V 4:1 with 11 × 8" folding propeller, Battery: LiPoly 11.1V, 1500mAh.
Airfoil: RG14 (semi-symmetrical), Wing Loading: 25g/dm², Flight Time (in dead air): approx. 30 minutes.

I invented a special mechanism such that on hard landings the wings can detach easily, to avoid damage.
