Update: Camera installed 20th july: I have donated my phone to put in the rocket. Even if the parachute doesn't deploy it will probably survive. It will be quite a rapid deacellaration. phones are made to be tough. The camcorder on it works and it will be in use shortly

Update: Parchute tests 19th July: Parchute deployed brilliantly payload to go in to the rocket soon. The recovery sysytem works. Thankfully there is a 2 sec delay for the parachut to deploy after recovery as it needs to unfold and open.
