    New round trip world record 100/200 Km!!!

    Hi everybody.
    At last my challenge for this year came true. I had planned this flight many times but the conditions never were as required. Two days ago everything worked flawlessly and the weather was special, thermals were amazing, sometimes the lift was almost 7 m/s.
    After a short motor launch (54 s.) inmediately I found a powerful lift that lead me to a convergence line of lifts topped by a long pop corn cumulus avenue.
    In 3 hours I was already crossing the 100 km milestone. I couldnīt believe it, the video quality was enough for a safe flight using the Heliaxial 12 and the RC link maintained 30-40% RSSI in the low output (0.5 W).
    The way home was hard until 77 km to go then I found a good lift that pushed the glider up to the cloudbase again and the wind veered to tail. That was time to relax and autopilot. In 5 hours total time I was landing at the base. I couldnīt believe it. The average speed was 40 Km/h, amazing if you think that the cruising speed for this glider is 50 Km/h. Almost all the flight was made with some tailwind component and taking advantage of magnificent thermal lifts.

    Here you are some tech information:

    Glider: Fascination (Top Model CZ).

    Completely blown away at the quality of the video at that range, a true master of the long range thermal soaring. Dam great accomplishment. What's next, you'd have to take into the account the curvature of the earth at the next longer distance.

    Congratulations Roberto!

    3. One to hold the light bulb and two to turn the ladder.
