Phillips believed that multiple stacked wing planes (or "sustainers" as he called them), in "Venetian blind" configuration, offered advantages.
* His 1893 Flying Machine had 50 lifting surfaces and used his patented "double-surface airfoils" in such a way as to produce an [[Aspect ratio (wing)|aspect ratio]] of 1:152, providing great lift at the sacrifice of stability. As a test vehicle, it was not designed to be manned, but was used to test lifting capability. Its maximum load was found to be {{cvt|400
* His 1904 Multiplane was a development of the 1893 test vehicle in a configuration that could be flown by a person. It had 21 wings and had a [[tail]] for stability, but was unable to achieve sustained flight. Its best performance was {{cvt|50

* His 1907 Multiplane, which had 200 individual airfoils and was powered by a {{cvt|22
Though successful, the 1907 model showed poor performance compared to more conventional contemporary types. This caused Phillips to end his attempts at manned flight.<ref>Angelucci, E. and Matricardi, P.; ''World Aircraft – Origins-World War 1'', Sampson Low, 1977.</ref>
