A newer old version that I altered the colors of, at one point

1 - Unlock / lock transformation

2 - Parachutes

3 - Engine power control unlocked / locked

4 - Open / close canopy

8 - Unlock / lock legs & activate / deactivate gyroscope

Yaw - Walking

Throttle - Transform / hand open & close

Pitch - Arms up / down

Roll - Robot mode steering

Robot mode flight:
Keeping the gyro active and the throttle around <50% is recommended, pitch controls forward & back, roll controls steering. Throttle somewhat controls altitude.

Jet mode flight:
Unlocking the engines & getting airborne before transforming (with the gyroscope active) is easier. Deactivating the gyroscope allows for more control in flight, though deactivating too soon is not recommended, along with using Trim to keep level without the gyroscope active.
