The receiver isn't really the main issue in distance (although a better vrx will receive weaker signals better), what you are going to need is a better vtx, or video transmitter. The more wattage you have (which is usually measured in milliwatts) the farther it will transmit. So if you are using a 25mw transmitter with that camera, try going up to a 200mw transmitter. I'm linking to one that I use on my quad and it works fantastic!
Here is the VTX I use -

Going to the goggles, if you are using rubber ducky (dipole) antennas, then get a cloverleaf antenna for whatever Ghz you are running. For the most distance, get a patch antenna which is very directional. Does the eachine go on the plane or in the goggles ? The camera has a mini whip antenna , I already ordered the eachine after you told me abought it lol
