MGL make really good products. On this, no caging is needed, from their manual:
"Extended range of operationBank operates over a full 360 degree range allowing unlimited use of the horizon for aerobatics, provided that maximumpublished bank, pitch and yaw rates are not exceeded. Maximum rates under normal operation are approximately 165degrees per second, valid for all three axis simultaneously. Depending on conditions maximum rates may reach 180degrees per second. No caging of the electronic gyro system is required during excessive maneuvering or aerobatics,unlike systems based on mechanical gyros. Simply correct the horizon when you are finished or let the horizon right itselfwhich will happen during straight and level flight."
