Leaving aside the charge to castigate the LAE looking after the aircraft that the OP flies, I think it prudent to share this with the rest of you,
Some of the Robin DR400 range have no toe brakes. To apply braking, you pull a lever on the centre console, and brakes are evenly applied. Large rudder inputs, or indeed steering angles while moving the aircraft on the ground, results in the brakes coming on, (possibly one sided) and this makes pushing or pulling it around on concrete tough going. This also exacerbates the large inputs issue when steering with the rudder during roll out.
Personal experience is that PA28 and Cessna drivers struggle to keep the DR400 in a straight line as it needs flown all the time that it is moving.
I love the DR400.
