Wouldn't expect that any first flight would last for 10 mins and probably less.
Take off , a couple of handling turns, check how the rigging makes the plane fly hands off , quick check of instruments and engine parameters on downwind, followed by a wide turn on to final to a landing. On a retractable, you wouldn't even cycle the gear.
The real work then starts to check if anything has come loose or needs adjusting/refitting / replacing.
