How to fix the "I am stuck behind a hangar on takeoff" issue:

Open Airfields.ROFCampaign in the RoFCampaign\Data\Inputs directory
Look for your airfield
Change the offset parameter (this number is distance in meters)
- Decreasing it moves you more towards the field (this is what you want to do if you are in the hangars)
- Increasing it moves you more towards the hangars (this is what you want to do if you are in the trees)

When you get the right value, let me know. I will make a permanent adjustment in the release copy of the config file.
