S.B.A.C, Show at Farnborough in 1948 (or was it 49 ?) the Airspeed Ambassador did the enire display with one engine feathered. The weight was not given.
( If the weight had been structurally limited by the limitations of an u/c currently undergoing trials, perhaps that one factor would have reduced the MAUW on the day. Just a thought!)
The power available from a nose wheel is greater than that from most tail wheels.
