You can make a 1v1, but you have to make another one or modify the mission to change plane type. The beta version of staged missions seems to work much better than the AHII. The offline drones in AHII are not aggressive, but they are aggressive in a custom arena. The Beta drones are aggressive offline. I can easily make a 1v1 if you tell me what plane types and if you want it for the Beta or AHII. Also if you want to spawn in the air let me know what altitude. I can post the mission file so you can modify the plane types. See the staged mission forum also. Also note that in air spawns don't work in AHII custom arena, but do work offline at least most of the time. We can use a normal takeoff and than a warp segment in a custom arena for AHII to get to altitude quickly. In air spawns work well in the beta in custom and offline arenas.
