Does anyone know if his Nimbus 4DM has had special
modifications to increase the vne at altitude, or does
he just not care about operating limitations?


Exceeding the standard Vne was not necesary for this record flight.


I don't have the POH of the Nimbus at hand, but the DG-1000 numbers
are this:

http://dg-flugzeugbau.de/Handbuecher/flugh-1000s-d.pdf page 2.3

Vne (IAS) at sea level: 270 kp/h
Vne (IAS) at 8.000m: 205 kp/h IAS = 317 kp/h TAS

TAS calculator he http://www.flightplan.za.net/trueAirspeed.php

Given the 15 kp/h higher Vne of the Numbus 4D and a similar
Vne/altutude calculation scheme I expect a maximum legal TAS of about
325 kp/h at 8.000 m.
