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:

Set Up:

Glider: Fascination (Top Model CZ).

LRS: Thomas Scherrer TSLRS (433 Mhz.)
RC: Graupner MC-24
Video Tx: 1.2 Ghz. 850 mW.

TSLRS antenna: Yagi 13 db.
TSLRS plane antennas: 2 standard dipoles.
Ground station video antenna: Heliaxial 11.5 dB. (Sircana)

Batteries: Lipo 16000 mAh. 3s
Camera: DX 201 Pixim
Ground station monitor: Tokai 13.3".
Video reccorder: Archos 604.


Total time: 04h58m.
Motor time: 54 s. (hand launch to 150 m height).
Batt consumption: 3280 mAh. (video, osd, gps, servos...).
Max. Range: 100 Km.
Max. Speed: 113 Km/h.
Outbound time: 02h48m.
Inbound time: 02h10m.
Average Speed outbound leg: 34.7 km/h.

Average Speed: 40.5 Km/h.

You can download here the KMZ file with the whole flight track:

Here you are the 100 Km. turning point screenshot:

And the maximums summary screen after landing:

The full flight video is ready. It takes about 11 minutes so it is 32X compressed.

Record 100 Km. (11 min 56 sec)

Oh, and one last : are you never worried about crossing actual planes way ? I usually stop thermaling my easyglider (!) at 1200m for this reason...
