We had a good flight day on Sunday at Doonside. Although the wind was fairly strong we managed to get 3 flights in.
The first flight was that of a modified rocket giving us a different perspective of the rocket. We were using the technique to investigate what happens inside the lowest bottle during flight. We mounted the camera on a long boom sticking out the side and looking back at the rocket and nozzle.
The full writeup with pictures and video of the flight is here:
I want to fly this one again, but actually remember to put the food colouring in it this time for better contrast enhancement. The fins also need to be painted a darker colour to work better with the camera's auto-iris.
