The 60HP Champ
Lightweight and Air-Cooled
Hexatron Engineering Company, Inc. has manufactured commercial aircraft components since 1982 and continues to be an FAA-PMA approved manufacturing facility building crew seats for the McDonnell-Douglas fleet of DC9, DC10, and MD80 Transports. Our facility is located in the northern part of Salt Lake County.
DEVELOPMENT
The manufacturing and production of the HEXADYNE P60 engine evolved through the development by Hexatron Engineering Company, Inc. (USA) in partnership with Weslake Air Services (UK) who provided, not only test cell services, but years of experience in designing and building formula one racing car engines - most notably Al Gurney’s famous Eagle.
MANUFACTURING QUALITY
We inspect every part. We perform thousands of individual inspections and thoroughly document each step of the manufacturing process. All in accordance with a MIL-I-45208 Inspection System that is FAA approved, even though the Hexadyne P60 engine is a non-certified engine.
Engineering, manufacture, assembly and production testing is performed at the Salt Lake City, Utah plant of Hexatron Engineering.
FEATURES
 | Our goal is to produce and deliver the highest quality, most economical operating lifetime power plant using proven engine control systems. The cost of ownership is minimized. |
| To justify full scale production, the proto type engine had to successfully complete and pass a rigorous test program on the Dynamometer in the test cells. |
| After initial trials, and many engineering changes and improvements, then after months of continuous running, the basic design was pronounced "go" and production started. |
| Significant advantages for a Hexadyne P60 engine rated against the HKS engines: |
| Lighter weight, by 10+ pounds |
| Larger displacement 800cc for Hexadyne vs 680cc means that Hexadyne has lower peak pressures and temperatures. |
| Engine management system - more economical less likely to suffer variations of mixture, ratio, less likely to ice up; less wear. |
| Cylinders in the Hexadyne P60 engine are in line eliminating a rocking couple vibration; engine runs smoother; less wear. |
| Engine mounts on the Hexadyne P60 engine are designed for rear 4 point dyna-focal mount. The HKS mounts are bed type. |
| The Hexadyne P60 engine is more compact in overall dimensions. |

Design
Crank case and cylinder design of the Hexadyne P60 engine is combined into one piece. This combination provides superior strength, lightness, short cylinder studs and the added feature of more accurate, non-porous structure from the permanent mod gravity casting.
Short push rods eliminates requirements for hydraulic lifters.
Low compression ratio, 9.0:1
Four (4) valves per cylinder provides greater valve area then two (2) and improves engine breathing (induction). While the exhaust ports could be combined into a single one, having two (2) ports permit better heat dissipation.
Plain bearings in the journals have the advantages over roller bearings, which are heavier, expensive and intolerant of wear.
Through finned openings in the cylinder head air side close to the exhaust valve seats, provides superb heat dissipation. In addition, heat is dissipated rapidly due to the rugged low end (con rod/crankshaft).
The engine management system allows for more uniform engine operation to provide considerably more specific output than a non-managed system (fixed, adjustable).
The engine management system adjusts fuel flow and ignition timing based on sensed engine variables including temperature pressures and engine rpm.
Elimination of the necessity for dual systems. The superior reliability of Electronic Ignition system coupled with stable proper fuel mixture ratio negates the need for twin spark plugs.
Both cylinders are in-line. Balanced forces act simultaneously on the same crankshaft at the same station, a major source of engine vibration in in-line engines, called "Rocking Couple" does not exist.
The Hexadyne P60 engine exhausts through each cylinder head, downwards. Standard short stack exhausts are provided with each engine. But each aircraft installation requires a exhaust/muffler system that requires special fabrication. Hexadyne Aviation will provide guidelines on design and fabrication to your requirements.
Cylinder/crankcase half, left and right, are gravity cast in permanent steel molds giving reproducible geometry. Heat treatable high strength aluminum alloy 356 is used. Engine sets are machined in mated pairs.
Cylinder heads are machined singly in a similar process.
