Ok, my first drone, Typhoon Q500 4K, is turning out to be a BLAST as I learn how all the various technologies come together to provide an exhilarating flying experience. I direct a STEM (science, technology, engineering, math) camp for young people. I'm always looking for new technologies to introduce to our summer activities. This summer (Ci 3.0) it will be drones. But having crashed 4 times in the past month, I need help. Help understanding what other's have experienced after repairing their drone from a crash landing. Here's a summary of what's taken place. had several successful flights over the course of 2 weeks lost control in a sudden wind gust that pushed the drone into a tree and crashed, breaking off one of the motor mounts ordered 2 new bodies from Yuneec learned all about desoldering and soldering, but didn't understand the significance of ESC and motor placements flew again, it lifted off to about 5-6 feet, very smoothly, then in an instant it took off on a sharp left, out of control, crashing into a pole, smashing the 1st replacement body learned where to put the ESC's and motors and rebuilt again (but didn't know about ESC ID assignment) flew again, this time instead of taking off it flipped over on take off, never getting off the ground, destroying my 3rd set of props called Yuneec customer service, Eric was extremely helpful, teaching me about ESC ID assignment and calibrations did the ESC ID assignment and also learned the app will allow me to override the 400' height limit fearful of another bad take off, I flew again, very carefully, this time it lifted to about 20 feet, stabilized, I tested rotations and turns, up and down, was working flawlessly switched to follow me mode, walked briskly to my left about 20 feet and stopped, drone followed along and stopped began to run in the other direction and suddenly, without warning, drone darted in that direction and flew away, crashing about 50 yards away, busting another motor mount and disintegrating my 4th set of props called Yuneec to return the drone for inspection - learned that if you keep an SD card in the controller, it will record the mathematical details of your flight - WISH I HAD KNOWN THIS BEFORE MY LAST CRASH So here's my question - assume something went bad after my first crash, that is causing the drone to do these random fly aways. Anyone else ever experience this? Any ideas on what it could be? I'm hopeful that Yuneec will be able to diagnose and tell me what has caused this and guarantee a fix. As a camp director, the thought of flying this drone with 40 campers scares the daylights out of me!!
