Polaron III payload attached

Last night I attached the payload section to the rest of the rocket. I also added a horizontal cardboard tube into the payload section. This tube will hold a second parachute that is pulled free when the deployed parachute opens.

A second parachute was added as this a fairly big rocket and one small chute would not have been enough.

The entire rocket including camera, flight computer and parachutes weighs 689 grams empty. It stands at 1520 mm long, with 110mm diameter.

The water fill capacity will be just over 1900 ml, so basically almost the entire lower bottle.

At the first launch pressure of 120 psi, the simulator predicts around the 125 meter mark, with slightly higher pressure and no camera predictions are around the 150 meter mark.

Hopefully the weather will be good this weekend for a launch.
