Here is the video from the last test, there is an offset to the right due to mis positionning of the support.
Also you can notice the limit of my current calibration for the heigh !
Zoom was disable and servo speed was a little bit to high, I hope the 10Hz GPS will improve the smoothing.

I tweaked some things :
- Changed setting in the neo 6M GPS (pedestrian mode for example)
- Added HDOP GPS base value on the OLED while not tracking
- Switched IR control to another µC, a mini pro 5V wired to the last serial output available on the mega.
It allow to send the command start / stop / zoom that takes 90ms without slowing the MEGA that is making the GPS computation.
- Ordered 10HZ neo 8 GPS
I tested 3 flight with 30min idle positionning to be sure that the FIX is solid, however the HDOP value from tinygps++ was never belove 95 .. I need to contact the guy that did it to ask some questions.
It worked well !! I need to upload the video on youtube, this time the test subject was my EXTRA 300 78" (2m) from Extreme flight.
It showed also that I need to tune the tilt angle computed from altitude.

The device did not work well, lot of offset for positionning ... video are garbage.
Zoom command is working but need tunning

=> Start and Stop recording : I implemented the command to start the recording and stop it when tracking start and stop.
=> For the zoom, the IR control was already working, the computation was not.
I will use speed / distance like the rotation to zoom or not. I added a switch to have 2 presets of "max_zoom" as in RC model video you don't want to zoom to much.
The only problem I have is the time used for the IR command as is take 3 x 30ms and increase my loop time decreasing the rotation response time.
I need to go to the field and fly my quad again, the goal is to find 2 presets that will be change according the speed of the airplane.

Not the first test of the V2 but one after disabling the kallman filter GPS 2D I found on github
It works great, need to smoth rotation and work on neutral position.

Video of the first version prototype outdoor.
For the first outdoor test my test subject was my girlfriend riding a horse, for the first test it is beyond my expectation !
It seems to be good enough for me to validate the concept and go on for CAD drawing, time to install sketchup and learn CAD.
