As a move action, you can expand one point of Ki to retract your wings into your body. While retracted in this manner, you lose all benefits and penalties from having wings. You can unfurl your wings again as a move action by spending another point of Ki.

While your wings are unfurled, you can fly at a speed of 40 ft per round.

Proposed Cost: 20 gestalt points (based on Carpet of Flying / Broom of Flying)
