After an extended period of evaluation and numerous delivery delays our new Hirth H37 engine has arrived.

Hirth have produced two stroke engines for over 100 years and we are very confident with the expected results. They are now a preeminent manufacturer of unmanned aircraft engines so we may be able to fit the Hirth to both our manned and unmanned helicopters.

Having 20% more power and 50% lighter than the original Porsche engine it replaces, we expect a significant improvement in the performance of our 20′ helicopter.
