Sounds all too familiar. I have a dual string stunt kite that uses kevlar lines, probably 200 lb test. The kite requires plenty of space and brisk winds to do its thing.. Since I can't fly it on my own property (not enough space) I used to put the kids and the kite in the car and head out to an open space. I could leave the house during a hurricane and by the time we arrived at a park or the beach, it was dead calm! I could run up and down trying to get the kite launched and it would not happen. It didn't matter when and where we went, I could stop all wind and air movement anywhere.
Now if I took my RC helicopter or something that required calmer air....you could bet your bottom dollar that the reverse would hold true.
Instead of giving up I pushed through and doubled up. I bought a small 28 foot sail boat. Surely that would sail with the wind...Not if I went out. By the time we reached the marina I would be motoring out of the harbor, motoring in the Gulf and motoring back!
I think I have a solution finally. I am going to start packing my drones and kites and go on the sail boat and have my wife follow me with the Whaler and see if I can trap Mother Nature into making up her mind. I have to win this battle somehow.
