Rotor tilt was controlled through gyroscopic precession. One effect of turning the front wheel is a roll moment caused by gyroscopic precession. Phase lag is a separate phenomenon from gyroscopic precession. Precession or gyroscopic considerations have an effect on bicycle performance at high speed. This difference is caused by phase lag, often confused with gyroscopic precession. There is an easy way to understand why gyroscopic precession occurs without using any mathematics. For instance, quantum mechanical spin can exhibit phenomena analogous to classical gyroscopic effects. Unlike traditional rifling, the rotation of the slug imparts no significant gyroscopic stabilization. Navigation relies on acceleration data, gyroscopic data, and global positioning data. Also, a faster-spinning discus imparts greater gyroscopic stability. Moreover, flywheels leak energy fairly quickly and affect a vehicle's steering through the gyroscopic effect. They would have a total angular momentum of zero and no gyroscopic effect. Florine chose a co-rotating configuration because the gyroscopic stability of the rotors would not cancel. The Wisps' powers are now controlled using the Wii U GamePad's touchscreen and gyroscopic features. They are grouped according to pitot-static system, compass systems, and gyroscopic instruments.
