of course! very sensible. I hadn't thought of that.

I am still not convinced though. In full size flying the gear is selected up as soon as a positive climb is established. To mirror that I hit the gear up switch immediately after the model leaves the ground.

As well as scale fidelity, that ensures that not too much airspeed is gained before gear retraction. I have seen many cases where the gear goes up late, by which time airspeed has risen to such an extent that the gear will not go up, or it fouls on a gear door which has been partially closed by the high speed airflow, often exacerbated by a bit of sideways yaw in a turn, or a bit of rudder waggling.
