TOP: Rotax is a big company these days, and the investments it has made in high-tech
tooling and quality control have paid off in many ways, most notably with much higher
TBOs,meaning lower recurring costs for owners.


MIDDLE: Even with the fairly large number of engines that Rotax builds, aero engines are
still largely handbuilt products.


BELOW: One of the key characteristics of the Rotax 9-series engines is their gearbox,
which takes the high-rpm of the engine, which is more like a car's engine in many ways,
and reduces it by a ratio of more than 2-1/2 :1 in order to get the prop rpm down to
2,300 or lower.
