have a phantom one (older version) and I have upgrade it to version 4:02. then I reinstall the Phantom, but now my controller is not working properly. I have this controller already recalibrated and sticks on the DJI NAZAM Assistant_2.20. after this stick calibration comes a text that says: After calibration, put all the TX sticks to their center position , and observe whether all the sliders shown in the software are in the middle position or not. If not, there is a problem with the TX owner´s manual to check / adjust the TX stick calibration ( for example, the Transmitter Calibration section in the advanced manual of PHANTOM ). Then click the ´view´ tab to check the center position deviation value, the value between -100 and 100 is allowed. (the left stick of the SR6 controller does not return to the center point). But I have already put the sticks in the middle. ((((for the update, I could put the left stick from the bottom to the middle so that the motors were running slightly harder (not flying) and when I put the left stick to the top the phantom will fly. ((((((after the update: i do the left stick to the middle but the motor does not running faster. and if I use the left stick to the top the motors run faster but increases the phantom not. please tell me what to do?
