For my videocam rockets, I use the Dolphin PenCam after I heard about it on info-central. It was $40. I used a rocket that was the BT-55 tubing. This is almost a perfect fit fot the camera, but it needs a little bit of tape to keep it sug in the tube. I would slide the camera into the tube and leave the nosecone off. I took and old estes launch key and epoxied it onto the bottom of the nosecone. When the camera was on and set to video mode, all I had to do was push the nosecone on, pop in the plastic rivets to hold it in place and launch. The key on the nosecone held the shutter button down so it would take video. When the launch was over, I just hooked it up to my computer and downloaded the video. I had and eyebolt attached to the top of the nosecone so the parachute would attach there so when the rocket was coming down, the camera would still be facing the ground, via mirror. Well, the video would always cut off after the ejection charge went off because the parachute would tug on the nosecone a little bit and make it let go of the shutter button. Well, that isn't a problem now. I chose a 7 second delay one day and it was way too long. The rocket came in ballistic and buried itself into the ground, well the nosecone at least. The charge went off a second after the rocket hit the ground. I figured it was a total loss. The payload tube was destroyed, and the top of the camera was shattered. The actual shutter button was ripped off of the circuit board!. Luckily, there was soemone who fixed it for me. Instead of using the button that I had to hold down, I attached a switch so I wouldn't have to hold down the button. Now, all I have to do is turn the camera on, flip the switch and run. I am now able to get video after the charge goes off. The crash was actually for the better! Anyways, here is the picture of the camera.
