Keeping up with AI?

[Remair]

I have been putting off buying/playing this game till the patch came out but finally gave in with the latest beta and got COD. It runs alright but I am having serious problems in the campaign.

I finally worked out that the hurricane's engine has to run for about a minute before attempting to take off but it seems these rules do not apply to the AI who take off and fly out of sight within a minute. With the non-functional ground control (how did they break what seems to be a direct copy+paste job from the original?) I have no idea where the leader went. I just get shouted at at 5 minute intervals for not being in formation. Is there any way to make the AI planes have the same engine requirements as yours so at least they have to wait or do I need to turn off CEM just to play?

On a side note does anyone know why my mixture setting resets itself every time I adjust the prop pitch or radiator?
