picture of access pipe
everything should be mounted inside the pipe
nothing can stick out, no solar panel, etc etc
the longer the battery lasts, the better, I mean, I have some 4500 mah 3s packs, they can keep a 1 kg quad in the air for 20 minutes, so I guess maybe power is not the most difficult problem (although the lighter the better, these batteries are 300 grams, the heavier the more difficult to mount without damaging the pipe, althoug minor damage is allowed)
designing the arms that will close and open the valve will, any ideas on which fora people might help out with these designs?
