Flysky IBUS Sensor

Not sure if you´re going to answer, but the IDE simply gives an error compiling for board when including and modifying the .cpp file. Any ideas? 12.6v lipo's surpass the 99.9v display capacity the Flysky has. Which means I need to use 42-35. Considering the diplay has a battery symbol, it isn´t much of a problem. But looking at the numbers and getting 38-39 doesn´t feel good.
