@vrandan just create a separate BBDOC and change settings until your character flys the way you want then put all these settings in your game play action. Also try checking out some of the presets and adjust them as needed and then you can also put those settings in the game play action. Just tinker around until you nail the settings down. I think that's the easiest way. Also if there are any build box users who have games that have the effect you want, you can always try asking them for some help as well.
Okay I will try if I need help on it later Ill pm you on what object and if you could do it I would really appreciate it
