I have gone off-grid solar last spring and have been dealing with the challenges of trees getting in the way of unobstructed sun on my PV panels.

Some trees just need to be pruned. But how to get a bull rope up there? Here's how I did it using my P4P drone and an appliance called Fli-Fli Airdrop:

The good old P4P.
Nice job!

Aloha Mark,

     Good solution!  BTW, where did you get the lift and release device?

     Take are and be safe!

Aloha and Drone On!

I bought that at least four years ago. It's called a Fli-Fli Airdrop. Here's their website. I may have bought direct from them. https://www.flifliairdrop.com/

I thought you were moving to Japan???

I was all set with a flight in April 2020, but the flight got cancelled due to you know what happening. So I'm stuck here for a while now.

Maybe Amazon or another outlet has them. Or there may be a competing product.
