What a week!
Rain, Rain, Rain and sometimes... Rain.
Not a good week for a launch.
Today was the first day to get a glimpse of the sun behind the clouds. So i used the chance for a video session and in depth testing of the new Catamarane hull (with the fins).
I tried various speeds, various payloads and various tracks to see if the new platform is stable.
It was!
1. A new speed-record with 10km/h (running with 8A and a 500g Li Battery-Pack)
2. The big battery-pack with about 1.5kg weight was also OK and had only a slight impact on the speed (about 1km/h slower). With that pack, the endurance of the ship will be around three hours with one charge.
(running with about 5A and a speed of about 6-7 km/h).
3. The straight-line stability on long runs was also OK, but still has some optimization potential.
After that runs, i had enough courage to mount my beloved Sony DigiCam (a DCR P100) with some gaffer-tape on the ship. I made two runs, the first with the cam attached to the front and the second with the cam attached to the aft. The aft-footage gives a nice look, how the ardupilot is controlling the yaw-servo.
All went well.
Despite the fact that the ship had a near-accident with one of the diving teachers of our club, who managed to surface at exactly the moment, i launched the ship.
Maybe we can make a bet, how much lawsuits for "malicious injury" i will have collected until the end of the year.
I have put the footage of some runs here:

Wondering if running a fishing line( just hook a fly fishing line and unlock the spool or what ever it is called) is good idea instead of rescue swimmer or will it cause drag behind?
