The rear engine was Teledyne Continental IOL-200, liquid cooled and 110
hp. The front was Continental 0-240, air cooled (and not as effecient)
130 hp, used for the first 70 hours and when climbing over weather.

Yeah - Rotax? Maybe the DAR was having a little joke.

As I understand it, they wanted to use one of the Garret F-109,
developed for the canceled T-46, but only a few were made and none were
available. The FJ44 was plan B, and not as effecient.
