Those who instructed on Das Teutor told me that it had an even worse roll rate than the Firefly
I only got just over 300hrs on the Firefly compared to over 600hrs on the Tutor. In my recollection the Firefly had a significantly slower rate of roll than the somewhat pedestrian Tutor. However, unlike the Tutor it didn't bleed energy in aerobatics, it was quite possible to complete an energetic sequence and gain altitude from 5000ft base height even with a significant use of - g. An outside loop was not difficult, my arms were too short for that in the Tutor which really bled energy.
None of which had much impact on its suitability as a basic trainer.
A much nicer basic trainer piston aircraft was the (unfortunately) tandem seated Socata Epsilon.
