why can't my drone fly more than 100 meters after the remote control is modified?
this is usually an error in the remote control during the modification process. it is recommended that you check the interface between the antenna and the remote control, and the internally modified coaxial cable. 1. the interface of the antenna is qma. when you plug the antenna into the remote control, you will hear or feel a 'click'. this means that the qma is in place; otherwise, what will block the signal because the qma does not snap into place. 2. you need to turn on the remote control again and check whether the internal coaxial cable is squeezed or broken? due to the working principle of the coaxial cable, after it is squeezed or broken, it will cause signal leakage. in severe cases, what will block the signal? 3. you need to turn on the power of the antenna during use. 4. select the correct frequency band in the hd setting item in the flight app. when using the pro series antenna, please pay special attention; you must lock the 'custom' and set the same frequency as the antenna. learn more
