We are going to repeat the runs over the next few days. This flight had slightly rising terrain so the signal was partially blocked at max range. The next flights will be from a location where the terrain drops away. This should improve distance. Also the battery on this flight was not topped off. Launched at about 95% and landed with 20% remaining. Some manual flight up to 40mph. Started run at 350ft and the altitude dropped to 190ft while in manual - that's a little scary. Will do the next runs in standard fly mode for better altitude control. 13,000ft is about the limit I'm willing to push and come back with reasonable battery remaining.
