Game Composites contacted us to manufacture the unique exhaust system and intake components to complement the streamlined cowling.


Anequim Project - UFMG (Brazil) - Fastest 4 cylinder equipped aircraft in the world.


August 2015: The Anequim Project has now officially met its goal as the fastest 4 cylinder equipped aircraft in the world. We traveled to Brazil to help the team with the record flight attempts and over a three day span we were able to set five new world records in the FAI C1A class.

The new records are as follows:

1. Speed over 3 km with restricted altitude

Previous record: Nemesis DR-90 - 466.83km/h (Jon Sharp)

New record claim: 521.08km/h

2. Speed over 15 km

Previous record: Nemesis DR-90 - 455.8 km/h (Jon Sharp)

New record claim: 511.19 km/h

3. Speed over 100 km closed course

Previous record: W.Air Race - 389.6 km/h (Richard Young)

New record claim: 490.14 km/h

4. Speed over 500 km closed course

Previous record: VariEze - 387.4 km/h (Klaus Savier)

New record claim: 493.74 km/h

5. Time to climb up to 3,000 meters

Previous record: Pushy Galore – 3 minutes and 8 seconds (Bruce Bohannon)

New record claim: 2 minutes and 26 seconds

The aircraft is using one of our AEIO-360 engines with the full complement of our products.

The aircraft is truly impressive in that it is a fixed gear, normally aspirated design.

David Windmiller - Edge 540

One of our favorite people and another incredible pilot from the northeast US, David Windmiller's Edge 540 uses a few of our products. His AEIO-540 built by PennYan Aero features our Lightweight Maxi-Sump system, 6/1 Exhaust, and Lightweight Flywheel (for LSE Ignition). In the next few weeks he will also be installing our new Top Cylinder Girdle kit and Air-Fuel Ratio monitor.
