I don't know if ya'll know this about spawns but they were made to mimic regular takeoff procedures. The current oneonone mission just has the spawn on the runway for convenience and a quick furball. However, it doesn't make for an immersive mission. The following is an example of how to take advantage of the AI movement:
Set your spawn points perpendicular to the initial TAXI segment and a reasonable distance away (spawn points circled in cyan):
When the mission starts, note how all the planes are seperated and visible to each other. This route with three flights of P51s were set to Spawn Type 'Vee':
Once the planes start rolling they will approach the point on the taxi segment directly in front of the flight. They will approach the taxi segment in order of fartherest flight from the end of the taxi segment to the closest flight to the endpoint. As you can see, it makes for a more immersive mission experience.
Anyway, you guys are doing great. Just thought I'd toss in something you may not have discovered yet.
