I've had my P3s 2 weeks and only taken it up head level 2 or 3 times. Once I purchased it I realized how intricate these really are and refused to operate it much until I felt a bit more informed, (not about the money, more about I don't want anyone getting hurt on my account). Using simulator with the blades off only wears down battery 4 or 5%, but you aren't supposed to fly unless you have 100% charge. Ex. I flew sim last night when I began I had full battery now it is at 94% should I charge battery and rc before actually flying today or does that weaken it? I've only had it on the charger twice in two weeks.
