Today in my distance experiment with the FPVLR I flew at close to 30 MPH to my destination and then was flying against a pretty strong headwind of 20 MPH or so and I got a low batter warning when still about 2,000' away from home. I came down lowered and then continued flying at 6-7 MPH until I was about 100' away and then landed. The battery voltage did not drop any further during that 1,900' or so leg. It got me to thinking that there is probably some optimum speed to fly at to maximize distance traveled on one battery charge. Top speeds are going to have more wind resistance, battery may heat up more, etc. Anybody have experience testing out something like this?
