It does not auto retract when you manually take off.
Is this in a waypoint or mapping mission? As it does auto retract the landing gear on a mission, but doesn't when flying manually. It also drops the landing gear automatically on a try, but again does not if landing manually.That is interesting. Because when I take off and I get about 50 feet in the air and the landing gear automatically retracts up. Then when it returns home the landing gear lowers itself down automatically.
