If you got it from Bangood you have to flash the flight controller, and reprogram it with betaflight, look at youtube videos, if you bought it from Grayson it came already flashed and programmed with the switches assigned, the error msg has nothing to do with it not flying. You need to put in 2-6 hours to fully get it done, it took me 4, Its annoying but so fun when you are done.
I believe this is on your flysky transmitter. Pretty sure its normal saying you are 99% error free. Does it arm and fly?
Im not the only one! This is how i got mine to but got too cocky and stuffed it up again. I went out and got anew laptop just a little one and then took it to a computer repair place and got them to load betaflight and the drivers $300 latter and i could have been flying but i got to into it and stuffed it up and now i have to reflash the board
