Plentiful power for sport and aerobatic aircraft!

Ease, dependability and performance are what make engines popular — and they're also three good reasons why the 46AXII has become an instant flyer favorite. Lightweight and low maintenance, the 46AXII is as good a choice for easy sport flying as hard-charging aerobatics. An extension cable and an angled high-speed needle make fine-tuned performance and maximum personal safety easy to enjoy.

O.S. 2-year Limited Warranty
