The He 100 had some problems with its condensation cooling system, but these were solved with an additional retractable normal cooler under the fuselage and the original condensation cooling system proved that it was able to take as much battle damage as well as normal cooling systems. The C serie proved that this fighter can carry a armament superior to all enemies of its time. The expectable dogfight tactics would have been similar to the F4U Corsair and Fw190A (hit and run). Why didnīt this plane succeed? Even with a standard cooling system (and no condensation cooling), it would have been still fast enough to be state-of-the-art until at least 1942! The only weakness I found was the small wing area of 14,50m2. It later would have limited the amount of additional armour, horsepower, armament and fuel and resulted in a high landing speed. In fact, the allies wouldnīt have had any chance in the Battle of Britain against 800 Heinkel 100D instead of 800 Me 109E!
