This E series was produced from 1958 through the late 1960s.

E series: These includes the E500, E510, E550 from 2003 - 2004.

A modular series, the E series had standard bores, with capacity increased using more cylinders or larger strokes.

All systems were developed in-house except for the later E series which was developed by Acer.

The E series was the final development of the prewar Waco line of biplane designs.

Model changes for the E series 3 are minimal.

The Luftwaffe continued to develop the E series.

Whether a E series Do 217 ever launched a Hs 294 glide bomb is unclear.

The E series was developed by Unisphere, which Juniper acquired in 2002.

Like previous models, the E series has the ability for a second (3-cell) battery in the modular bay.
