Hey JazAero... Take a look through this guys material https://onedrive.live.com/?cid=cbcd63d6340707e6&sa=822839791
His name is Phil Thompson (goes by the name "SpazSinBad" on many forums) and is an ex Aussie scooter pilot from back in the day. He is very knowledgeable on the A4, and has tonnes of info. I began developing the A4 for FSX some time ago and he was quite happy to answer any questions.
