And the rest

Shame that's a captured "recon" bf110 and not a fighter/bomber configured one.

Interesting reading all the same especially the Hurricane comparisons.

True but the differences would not have been great. They allowed for the missing guns and the weight of the armour would seem to have been the main difference and that isn't significant, indeed one would expect the Recce version to have a slighjtly better performance.

Yes it is possible, you need to set the dead engine feathering position, and dont forget to close ALL radiators from the engine, not needed to be open anymore, to reduce drag.

You should fly straight and level well trimmed with 250-260 km/h, and be able to hold ALT. If you are light, you are able to climb a little even, with 230 km/h, but I would not do it if not needed. With the graph from Kodoss what is showing one engine 280Km/h, I am not able to do so.....;)
