We prefer power units with light aero-modelling engines that are modified for the liquid cooling and supplied to us by the Leonardo company, represented by Mr. Eduard Holánek. Currently there are two Praying Mantis 2 (Kudlanka 2) machines in operation, powered by the horizontally opposed (flat) twin-cylinder ZDZ-210B-2RV of 210 cm3, made by the ZDZ Valašské Meziříčí. In the nearest future we expect finishing the development of a 120 cm3 flat twin – see below.

This is the future "wild heart" of our Praying Mantis 3 (Kudlanka 3): the engine weighs 2,7 kg, its presumed output is 12,5 kW (17 HP).
There is no stopping to progress – new engine – MANTIS model. (technical data - see backpack)
Welding, cutting and drilling in precise tooling and assembly jigs guarantee the absolute interchangeability of spare and replacement parts.
Prototype after completion with carbon fibre parts already in place
Our comfortable harness under test; it is adjustable to fit various sizes of human body
Have you ever been so nervous during a flight with a backpack that you made some mistake? Now you now longer need to worry. New Kudlanek microprocessor technology will think for you!!!!!! - automatic pinion uncoupling at engagement - never starts when motor is running - never (drowns the motor) - handle includes battery under voltage indicator - fully functional fuel gauge - over-heated motor indicator - A boosted starting relay on limiter current around 300 A Are you still worried?
