Engine on Kohler powered tractor will start and run for 2-5 minutes then die. It will not crank for 5-10 minutes. After...

There are 2 motors that turn clockwise and 2 that turn counterclockwise. The props are also different and each is marked to go on their matching motor. On each arm of your drone there is either an A or B and on the props 2 have an A and 2 have a B. Make sure that the props are on their proper motor. I don't feel calibration is your issue but.....to recalibrate the gyro: After you bind your Tx and drone with the up/down throttle sequence(and have solid lights), move both Tx sticks to bottom right. The gyro will recalibrate after a second or 2 and the lights will flash then return to solid. I hope this helps and you are flying again soon if not already.
