This interesting model encompasses several recent developments in radio control equipment. Specifically, the brushless motor mixing technology that is commonly used in R/C drones, combined with 3-axis gyro stabilisation that is now fitted to many model aircraft - drones and planes alike. Based on the Canadair CL-84 'Dynavert' experimental aircraft, it is able to take-off vertically like a helicopter or drone and then transition into forward flight where it flies like a standard R/C aeroplane. Due to the unusual nature of this aircraft, this is one model where a thorough read through of the multilingual instruction manual is highly recommended. Printed in black and white, it contains step-by-step pictures to guide you through the assembly. It is all very straightforward but it is the connecting up of the additional 'electronic board' that requires additional attention, as well as a good understanding of what to expect when flying the model for the first time, especially when transiting to and from straight and level flight. The instructions call for 'a certain level of model flying expertise' to be able to fly the CL-84 and having done so I would say that you should be a competent fixed wing pilot and have a good level of outdoor drone and/ or helicopter flying experience too. Having said this, the CL-84 is not a difficult model to fly and should be within the capabilities of most competent club level pilots.
