The Dragonfly JB3 Helicopter:

The Dragonfly JBIII helicopter is a remarkable piece of aviation engineering that combines efficient design with robust performance. With a maximum gross weight of 1,540 lbs (699 kg) and a useful load capacity of 584 lbs (265 kg), this model offers an excellent balance between weight and payload, making it versatile for various applications. Its lightweight yet durable frame, paired with the powerful Garrett PBS turbine engine delivering up to 240 shp, enables this helicopter to achieve a commendable cruising speed of 80 knots (148 km/h) while maintaining fuel efficiency. The Dragonfly also has a maximum speed (VNE) of 110 knots, providing a significant range of operational flexibility.

For those seeking an alternative to the turbine, the Dragonfly can also be equipped with a UL Power 520i piston engine, running on 98-octane MOgaz fuel. In this configuration, the empty weight is 1,275 lbs, offering a lighter setup that maintains high performance and fuel economy.
