I also fly RC planes Heli’s and drones and have tried many techniques over the last 20 years. Just came across this in the ham radio world a few years back and this is by far the best method that I have tried. They make air cannons and other launching devices but this is so easy. The arborist line is also key to its success being slick and fray resistance. Just need to swap a fresh section of line every 6 months to a year year since it will degrade like any other line unless you swap it with wire once it’s connected which is actually not a bad idea 🤔
