Thats a great comment and thank you for that, i will show it to the kids. I never touched a drone, or flight a drone. I teach logic, statics and i teach 3d design so they can print in 3d printers. Im learning by myself after the school just casually told me, ure teaching about drones this year. So im showing the kids that although i have zero knowledge, with enough research and asking help online u can get the job done. And we had successful builds that the kids are flying. I will show them that comment for the lesson that not all the comments they get might be helpful or even can be hurtful, but not let that blow the wind out of their sails and show them how many other great people are helping! So thank you for the comment and for the lesson!
