German engine manufacturer Stuttgart Engineering have developed a small turboprop powerplant aimed at the LSA and home build market, which promises to create a sensation when it begins flight testing in later this year.

The company is developing two versions, 100 and 130hp. Both have more than 800hrs on the test stand in all flight regimes, burning an average of around 38lph of diesel fuel.

The engines weigh 28k g for the 100hp and 30kg for the 130hp and have a length of 555mm.
