After many months of hard work, we are proud to present our biggest update yet!

New/improved features include:
 * mini zoom window: make those planes easier to see
 * new plane: ducted fan F18 jet! It's fast and it has massive control surfaces for a wild ride.
 * advanced controller LCD screen (In-App Purchase):
  - expo and rates adjustable for each model
  - adjust trim for each model
  - new quadcopter modes:
    + altitude hold
    + acro mode
    + expert (acro with blend) mode
 * retrimmed all models. Most are trimmed for level flight at about half throttle
 * better iPhone 6 and 6+ support
 * tried to clear up confusion between 3ch and 4ch planes

User interface improvements:
 * nice big fly button so you can get back to flying faster
 * selection swiping direction is now always consistent regardless of portrait or landscape mode
 * relative stick controls: you can now touch anywhere on the control and drag your finger to adjust the stick. Releasing your touch will spring the control back to center.
 * the stick areas are now bigger for some devices (eg iPhone in landscape).

Numerous improvements to quadcopter:
 * IMU calculations: now stabilizes better from upside down
 * quadcopter always starts pointing away from you.
 * quadcopter props now break properly in a bad "landing".

Some minor tweaks to physics and general handling.

Wind! Each field now has different wind conditions.

New model for scale fun flying: P51! (and changed the icon again)

Tweaks to aerodynamics for some of the models, mainly for more upside down flying fun.

Rudder and aileron guide dots: know where your rudder and aileron sticks are pointing. On a real controller you would feel the feedback from the stick springs.

Added mode 3 and mode 4 controllers.

Updated docs for wind and quadcopter flips.

Quadcopter! Full simulation of 4 motors, 3 axis gyro and PID controllers. Practice flips!

Updated for iOS 7.

Improvements to sound. Also, your music will now keep playing when the app starts (there were arguments in the dev team about who was to blame for missing this one)

Update to the Antigravity Trainer.
