From the Developer – Flight Unlimited Helicopter Review

We are aware of the control issues and the flight model issues. It's a bug in the flight engine that made it past testing. We're working aroudn the clock to fix the issue. An update will be released next week with the fix. In the mean time we've made the game $0.99 in an effort to make up for the issue. We have our flight model physics team on the case. In addition to fixing the bug we will update the physics engine to make it more accurate. We will also include a free additional helicopter for you to download. Thank you for your patience and support of the game. We are dedicated to making this the most accurate helicopter flight simulator in the app store. If you have any comments, questions, or concerns, please don't hesitate to visit the webstie and email us.
