Interesting first build!

Hi I am very new to building but not to rc. My uncles all build and fly rc planes, and when I ask for help they are useless, personally. So I'm coming here. A buddy of one of my uncles builds racers all the time, so I home to build me a dji f450. He said he flashed it with simonk and clear sky, (if that sounds right), anyways been flying for a month now, (actual flight time), and the other I was flying and someone moved the ground on me. Needles to say ordered the parts changed everything out, and my uncles friend said I need to recalibrat the esc's. Okay how do I do that?, and he said check youtube. Then he basically falls off the earth. I haven't heard from him since June 21st. So I think I did everything right but now when I'm just hovering in front of me I see one of my motors is dipping even so often. Now noticeable change in any other flight. So did I not do something right or maybe just a bad motor? Please anybody. I'm in it for the long run. Thanks

Not to add to the many different things you've been suggested and confusion but I'd suggest BLheli if you already have the tools to flash. It is a lot smother than simeon K and really helps flight characteristics. If you put the quad in accro, or stabilize mode (just normal flight wihtout autolevel and all of that) do the motors start up at about the same time? If not you should calibrate. Some ESCs are differnet, and if they program via sticks you can mess some thnigs up, but normally you turn them on while they have 100% throttle, they do some beeps, and then you drop the throttle to 0%. After that they usually do some beeps and then when you move your stick up they will spin up.

As a saftey and as part of it's job to stabilize the flight controller does not allow you to give raw stick input unless it has a mode called throttle passthrough, if you are using the KK2.x.x it will do this if you push and hold the far left and far right buttons while powering it on. Hold those down while you start the stick out at the top, then move it down or it exits throttle passthrough mode.

One rather easy way to do it is to connect the 3 wire cable from the ESC directly to the throttle channel on your pwm reciever ( a reciever that outputs PWM which is about all cheaper ones).

I hope this helped rather than adding to the confusion, but if you have any questions feel free to ask.

Yes this does help alot. But that's what I thought I did when I connected it via micro usb. But I guess I gotta do it manually. It's real easy for me to understand when I take things apart. Maybe I should've build it myself. Haha. I do have other questions but one thing at a time I guess. Oh I don't have anything for flashing.
