THE PREMISE

The “Shock Ultra” represents the natural evolution, into an Ultralight version, of our LSA Shock Cub, an aircraft created in 2016 and proposed with an overall vision and specific technical features, strongly oriented to bushflying. The much-appreciated growing demand, for our more-specialized aircrafts, even in the European market, where most of the time, “empty weight” represents a critical factor, has led us to design an Ultralight version of our Shock Cub which could satisfy and be compliant with some of these European Countries strict regulations.

Through the general weight saving process, which has impacted the whole airframe, keeping at the same time a 600 kg (1.322 lbs) MTOW, we have managed to reach a minimum empty weight of 340 kg (750 lbs, with Rotax 912 ULS-100 hp) including radio, slats and a specific optional weight saving program, which offers carbonfiber parts, light weight battery, oracover in place of classic heat-shrink Dacron, etc. The effort necessary to obtain this result has required a long, meticulous revision and optimization of the whole airframe, of the cockpit interiors, of the brake system, of the suspensions and of the wing’s structure with its control surfaces. A new basic engine cowling, derived by the one of our Savage Bobber, helped to reduce the overall weight too (an optional completely enclosed cowling is available on demand).

Our work has enabled us to propose, to all markets, where it is requested or desired, a Shock Cub in all respects but more lightweight. The consequent outstanding characteristics, due to the Hyper STOL behavior of our wing, together with the extreme lightness of the aircraft, allow us to confirm that we have reached a class of performance which can be considered at the top of the market, in all those phases of flight below 60 km/h (37 mph, more typical for a Para-Motor than for a robust 3 axis aircraft), all the while maintaining interesting cruise speeds.

The name “Ultra” has been therefore chosen, especially to embrace all these factors, creating the perfect link between the superlative performances of the more powerful and heavier Shock Cub and the need of a lighter aircraft.
Shock Ultra, “the lightest” aircraft specialized for bushflying on the market, is ready to meet your requirements with no compromises and no inferiority complexes.

The plane was even chosen by Microsoft /Asobo Studio, for their new Flight Simulator “MFS 2020”.
The Shock Ultra is our second plane inserted in this simulation game, being our Savage Cub, the first one.
