I have run gas engines ranging from a single Zenoah 62, First Place 4.2, First Place twin cylinders, DA 150, and Moki 250 radial. I did not used a header tank in any plane, and never had a single engine stop in flight. So my personal opinion based on experience, it is not needed.

CH,


Gas engines all (virtually) have a diaphragm pump in their Walbro/Tillotson carburettors, to easily draw fuel from anywhere in the model (tank on C/G).

They don't need a header-tank, so there are obviously only cons (another potential point of failure); no pros at all...
