I install anything new on my quad, and the weather will immediately become wet or gale-force. Works infallibly! Worked again today - got the new immersionrc 600mw installed, and in came the rainstorms. I could make a fortune breaking droughts all over the world - just turn up with my quad and use all the money from the last job, to put on some exciting new mod, and the storms will arrive. They can pay me generously and I can use that money for the next mod that I'll use to bring the next rain. I wonder if it's still "commercial use" if you make money from NOT flying it?
