I want to run the following mission & am looking for any feedback or ideas to help make it successful: using a Phantom 3 Standard I'm trying to lift 2 sodas (24oz) to approx 200 ft, run a 1 mile out-of-line-of sight mission (using the Litchi) that delivers the sodas. I'm dropping them off using the Israeli Sky Hook then returning to the initial lz. My main concern is will my P3S carry the load that distance? Anyone have experience with this?
I can't tell if this is a joke or not. If you consider it to be a thought exercise, then some simple math would tell you that this isn't going to end well for the soda or the AC.
If a 12 oz can of soda weighs a bit more than 350g, your 24 oz cans together are going to be 700g. If you are using the Drone Sky Hook, that weighs 49g, so figure at least 750g or so (not counting the container holding the soda). The P3S with battery weighs 1216g, so you are increasing the weight of the drone by a bit more than 60% and making it seriously off balance (Sky Hook mounts on the side). To fly that payload for a mile is going to be putting extra stress on the motors. It's one thing to use a Sky Hook to launch a glider or drop a fishing line, it's quite another to run an entire Litch mission that way.
To drop the payload from a P3S, you are going to have to rotate the AC a few times counter-clockwise. That's the only way you are going to trigger the drop mechanism. Dropping it with a parachute is going to need at least a
parachute that is at least 30" around. This assumes that you can find the sweet spot that the package was dropped from a higher enough altitude for the chute to open up and slow the descent enough to keep the cans from being too shaken up to open and not hitting anyone. At 400ft, you have about
4.9 seconds before a released object hits the ground. I can see going through a lot of soda getting that one setup right. Too low and "splat". Too high and you'll have no control over where the chute will carry the payload. Which way is the wind blowing at the LZ? That's right, you wont know when you are putting in the Litchi mission.
Or you will set the AC to be low enough to the ground where it can set the soda down. The altitude control is good, but you have no control over wind or curious bystanders. A spinning AC, low to the ground, near people, and beyond VLOS is wrong on so many levels I don't know where to start. If you are in the US, you can start with it being illegal because of the lack of VLOS.
If you want to do this because of it looking cool, then do it within VLOS. And practice without anyone near the LZ. It will look just as cool from 100 ft away and you reduce the wear and tear on the motors.
