After connecting up the motors, and the battery (props still removed!), the moment of truth was there... No smoke! So no electrical shorts yet. Then for the first time ever spanning up the motors! I had attached a piece of sticky-tape to the motor shafts, so that I could see the turning direction (the tape bends due to the forces of the air, and stays deformed after stopping the motors). Of course, two out of 4 turned in the wrong direction, so I had to swap two wires per motor to get that corrected. I had deliberately connected the motors with bullet connectors, both for modularity, and for being able to quickly correct this. After swapping the wires, and one last check of the spinning directions, it was time to mount the props. Again, observing the turning directions. Then, outside, with the quad in my hand - looking out for the diameter of the props to be well clear of anything, especially my arms - a first spin-up. With about 1/3 throttle, I tested out if the corrections...
This blog is all about my flying adventures with unmanned vehicles like drones, and model airplanes. Initial focus will be on my self-built drone project. As time progresses, I'll fly different drones and airplanes, undoubtedly, because this is such an addictive hobby!
