Flew 328 feet away attached to a 600' roll of rope and dropped it onto the target.
Just testing to see how mavic performs.

The intent is to use a Gannett bait release. I didn't have one, so I built a realease mechanism for about $5.00
It senses when mavic's red led is turned on.
You can turn the led on/off with the app.

Outstanding proof of concept!! That will be a very helpful tool!
Thanks for sharing. I don't want to wish people into danger but it'd be neat to see a real rescue.

I am not a very good videographer, but I want to film a somewhat realistic "ice rescue" video and actually deliver a rope/floatation device to a "victim" Who has fallen through the ice.
I have been talking to a local fire department near where I live to see if I can do this during one of their trainings.
It is not practical to do it at work because of certian restrictions. I am a career firefighter.

Move and pin this to the mod section
My kids are going to trip once we start dropping parachute men (from a reasonable height)
Wonder how light we can make this,
first change I would do is go with 2 CR3025 batteries and measure the expected life
2nd maybe the micro servo, I know for your scenario a larger motor maybe needed but parachute men, nope
3rd loctite has a great 2 stage plastic glue that may help reduce the amount of Legos needed

I like the idea of a solenoid. This one only moves 2mm - 5mm. I wonder what sort of rigging would be necessary to make a drop machsnism with this or if a similiar one with 15-25mm stroke is available.
The voltage needs to be a minimum of 5 volts plus the one thing that we would need to be cautious of is the magnetic in this device.
The next modification I am likely to make is adding 1 more battery to increase the voltage to approximately 4.5 volts.
Under heavy weight, I often have to jiggle mavic back and forth slightly to get it to release.

I am not an angler but was researching fishing line the other day and am impressed with how strong and light some of it is.
That would make for a fun "rescue." Flying 1/2 mile away and attaching a line to a boat.
Excellent question!
I was searching for the strongest lightest rope I could find and ran across this. It's lighter than paracord and 3x the strength. Plus it floats and looses no strength when wet...and is super chemical resistant.
