Hi Mark,

Interesting stuff... Petrol power in F3A would be nice, simply by reducing fuel costs and complexity of the engine... Now if only DA would make a rear exhaust version of the DA50...

BTW, the ZDZ engines are available through Amelung in Germany [link=http://www.zdz-motor.de/]http://www.zdz-motor.de/[/link]

For a pipe look at the new ES composites pipe made specifically for the ZDZ 40: [link=http://www.escomposites.com/test_stand.htm]http://www.escomposites.com/test_stand.htm[/link]

Good luck, and let us hear the result!
