I am building a quad copter that will weigh at most 5 pounds. It will need to fly a long way ( not sure but a mile? maybe more), but I am looking for efficient motors with a low amperage take so that the battery will last longer. I was planning to use a 2300Kv motor with a 6" fold-able propeller that has a 35 amp continuous take, but I realized that it was relatively a large amperage take so i started looking at 15 continuous amperage. I was looking for a professionals help on picking a motor for this drone. I am looking for mostly longevity ( so lower amperage take?) that will fly at around 500 feet AGL. I am also looking for a good battery to use, right now I am looking at a 3 cell 5500mAh battery with 50C, but I have to take in account the weight of battery. I am also using a random 4-in-1 ESC with max 40 amps I found since i didn't think it would be that important, but any feedback would be cool too. I was planning to use the 4-in-1 ESC for less weight. We are using the Omnibus F4 pro with a Beitian BN-880 GPS module that I found recommended by INav...is that a trusted GPS module to use? The flight controller comes with a barometer so I was planning to use this all together to program the drone to use the autonomous Way point method or an RTH option. I'm not using any camera. For the transmitter and receiver I was going to use the cheaper option of the TBS crossfire module, which I found to be the FrSky R9 module to extend the range. I am planning to have the drone autonomously going to the way point then manually landing it, but it will go up as high as 5000 feet. Is the FrSky good enough or is the TBS Crossfire going to give me less issues? The transmitter I am using is the Taranis X9D with the FrSky R9 module attached. I am new at drones so any help is highly appreciated on what to get.
