I am attempting to use this application to plan flights for a drone carrying payload with an RFID reader. I’m not interested in mapping or photography. I just need the drone to fly in a defined pattern at a defined speed at a defined altitude. Your application seems to meet my needs perfectly except I need to be able to fly at 7.5m and at 17.5m. Both of those altitudes seems lower than the minimum your application allows. Is there a way I can force the application to allow my drone to fly at 7.5m and 17.5m?
