One of the major problems of the new class of 4-inch long-range quadcopters (Flywoo Explorer LR 4, Diatone Roma F4 LR, and similar) is weak GPS performance. Some people suggest twisting wires, some to power up GPS before VTX, but deep down, we all know that this kind of magic solution only masks a problem. You need a better GPS module.
