Onboard the Graupner kleine RC-Uhu of my son. He gave me his permission to fly it :-)
AUW 305 gram
Propulsion: 240 rubber bands and 50 meters of fishing line.
Onboard footage shot with Flightcamone2 (FCO2) adding 60 (equals 20%) grams and a lot of drag, hence the short flights.
If you have a 9-year old son who likes to fly RC-aircraft like you do, buy him an Uhu and build it together. It is so rewarding.
