It was bought without a receiver and although I fitted a FrSky S8R, I never used the gyro facilities whilst training.
I had high / medium / low rates set up, but my instructor was very keen that I should learn to fly 'properly',
and we only ever used high rates.
Since I passed the test, I have had a play with them, however!
Having seen several other people bin their Discoveries, I like having the option of an 'automatic level mode' switch.
