"Have you performed an AutoTune or have you tuned the PIDs manually? If you haven't, the drone doesn't know how to control itself and although it might look stable in certain conditions, in windier environments for example it might lash out of…"

"Hi, yes I did. As far as the frame, here's everything I've learned so far. As it comes from China you might want to sand the edges as they're rough compared to higher quality products. You might also want to rinse with water and some cleaning…"

"Hey bud,

I plot your flight log online here: https://plot.dron.ee/2G4l
Reading the motor outputs while you seem to try to just hover (right before your copter flips) -- I can see your RC2 and RC4 (back motors) being almost at maximum output. If I…"

"You guys are also going to need some toy drones to practice flying if you're not good at that yet. Best of luck. "

"From my observation racing drones are very powerful but also very inefficient. I don't think doubling the battery size to a small drone would work, the reason is because you're also adding a lot of weight. I think you'd get somewhere around 10…"

"Okay, in order to stay up in the air for that long you'll need high efficiency. The bigger the propeller, the higher the efficiency, but also the bigger the drone. I think the smallest form factor that you can use might be a tricopter, but if you…"

"Are you allowed to come down and replace battery? Mustafa Dogan said:
20 minutes. But not all drones will take off same time. So let's say 23-25 minutes"

"Bluetooth has a very short range, I don't think that's a very good idea. What gimbal is it?"

"Hey, I like the idea of it being a small drone. The limitation with that will be battery life will be 3-7 minutes. What's your competition round time?"
