Maiden flight

Today was the big day, the maiden flight of the ascending aid. I choose a small hillsite near Toledo (Magan, Cerro del Aguila) for this first test as the height is only 90m and I had to go back by walking with 15kg of equipment and 4kg of motor/battery.
The wind direction was perfect for this site, north-west with about 5-8 km/h. The test was conducted with the old battery set and the 30" propeller with 10kg thrust.
The ground handling is very easy, the battery pack does not disturb too much. The start procedure is like a normal paraglider. The motor is switched on when airborne to prevent any hazzle with the lines. The motor is also switched of before landing for the same reason.
I flew 2 nearly parallel tracks to compare the sinking speed with and without motor. You can see the details in the track log. The 10kg thrust gives me a ascending rate of about 1m/s. It could not compensate the 1,2 m/s sink rate at this moment, but it would have made the flight much longer if I wished.
Next time I will try the 40" propeller with 15kg thrust. In this configuration, a positve ascending rate should be possible.
