How to flip the aircraft for backwards flight

Method 1 or the cool method

Step 1: bring the VTOL to neutral
Step 2: slightly yaw the aircraft
Step 3: when backwards yaw in the same direction to stabilize the aircraft
Step 4: bring the VTOL back up or down in the opposite direction

Method 2 or the slightly less cool method

just go from VTOL up to VTOL down and stall the aircraft

THINGS TO KEEP IN MIND

• Yaw is overly powerful
• Yaw is inverted when flying backwards
