Im trying to make a mission in CFS2's Mission Builder using Add-On jets as the default aircraft. 

However, the AI jets dont want to follow their waypoints like the stock props do - they just fly round the mission area in a wide circle doing nothing! 

I've checked my wapoint commands dont say to 'loop' or 'loiter' and tried moving waypoints but it doesn't help.

I was wondering if anyone out there has had the same problem and knows what to do to fix it. 

Any ideas would be really great! 
Thanks!

I once set up a simple mission, where 4 of MaxTac's P-80s engage with 4 Ta-183s. Was a pretty interesting dogfight. One of my wingmen shot down 1, I shot down 2 then proceeded to spin into the drink
