The new version 2.00 software of P2V has a serious bug. When you set a new Home position, by flipping S2 5 times, the altitude of the new position is not set. Instead, the altitude of your original start position is kept. This is a serious problem in areas with hills etc. Scenario of what goes wrong: - Start in a valley. I call this altitude 0. - Fly to a nearby hilltop of say 50 meter altitude. - Set new Home position. Now 2 things can go terribly wrong: 1. Fly back to the valley and switch off the controller. P2V will climb to 20 meters, turn towards the hill and fly straight into the hillside. 2. Fly to 80 m altitude and switch off the controller. P2V will fly to the hilltop position, then crash into the hilltop with a vertical speed of about 3 m/s.
