The test model measures about 7m long, 5m wide and 2m tall, and the purpose is to test its technical possibility of a payload capacity of over 200kg and a cruising range of over 100km, and further, to evaluate the product marketability as a “flying pickup truck”. It has 8 motor propellers powered by electricity generated by three of our high-performance Ninja ZX-10R motorcycle engines.

And while pocket-sized jet engines have been boosting radio-controlled model airplanes for decades, the company calls the Monarch 5 the first commercial-grade microturbine.
