New Honda Aircraft Engine Breaks Cover


Well, not really. But we found this project while practicing a little work avoidance (ah, that would be research) here at the KITPLANES world headquarters. It is a nine-cylinder radial engine made up of Honda XR600 dirtbike cylinders and heads. These are single overhead-cam engines, requiring a clever multi-chain cam drive system. The case is CNC-machined from billet aluminum. The workmanship, by Aussie Ian Drysdale, is evidently amazing.

Sorry to say, this amazing engine is destined not for an aircraft but an air boat.
