Hello, I fly just for fun, not a racer, not aerial photography, just fun for me. I have been flying the 65mm "Tiny Whoop" class drones. Mine are of the "Toy" classification as I fly mostly inside. I have watched numerous YouTube videos for upgrading. Although I have done most of the standard modifications (batteries, motors, props), I don't buy the expensive flight controller boards and I don't have a costly radio transmitter (remote controller). What I fly inside is either stock or have only minor upgrades. On the other hand, I have done some "frame kit" builds that include everything but the flight controller board. I just use a board from one of my toy quads (mostly Eachine E013, E010, and Furibee F36). I also build my own canopies and antenna guards. I am looking for a place to learn more and share information. iFly4Fun
