|Dan explains the basics of rocketry to Monte Sano 4th graders|
The Snitch was launched for the 5th graders - it flew to about 70 feet or so, landing right beside the school building. One rocket launched, one rocket recovered. Der Red Max flew for the 4th graders; it was the one I was almost sure would hang in a tree, as it returned via parachute. Fortunately, the wind was calm and the rocket missed the trees by a few yards. Two rockets launched and recovered. Last up was my flying badminton birdie, which had the best altitude of the three flights on its A10 motor. It too landed right beside the school, making for 3 perfect flights.
The Go Pro Hero was easy to operate using my iPhone. I managed to get it pointed so that it got some launch video looking "up the tail pipe". The day was cloudy, so the vids were a bit dark; I was pleased nonetheless.
Here is a 1/3rd real time movie of the Snitch leaving the pad, created from the 100 fps footage:
and this is the real time footage of the Der Red Max flight. I love the kids' enthusiasm, and was amused by their reaction when the ejection charge fired. Even though it looks like the rocket was heading for the tree on the right, it missed it.
The rain moved in soon after the Birdie launch; it was a good thing our stuff was scheduled for the morning! Next year I will bring more motors along so I can fly for each individual grade. Of course, I will probably hang one or more in a tree then, given the perversity of Mother Nature.
