The helicopter reconsiders. CH77Ranabot

We thought we had made our idea come true, but dreams do not seem to end. And so we have reconsiders the whole world of light helicopter.

Ranabot Ch 77 projet R, reconsidered the Ultra-light helicopter for Europe and the world, in the light of new national regulation as well as new prospect of the sector.

Sport flight has grown, and our helicopter have been following its evolution since the beginning.

Ranabot reconsiders the light helicopter starting from weights, capable of remaining us this the legal limits of the class despite the profound evolution of the aircraft.

Ranabot reconsiders the interior space of the class with new cabin with side by side seat, to meet the needs of the pilots in terms of practicality, interior space and comfort on long journeys .

Ranabot reconsiders technology with experience ,the result of 20 years working in the sector, synthesized and further improved .

Ranabot improves and optimized the characteristics of the propulsion unit, while also reducing cost and maintenance cycles with tbo at 2000 hours and EPA POWER technology.

And we also reconsidered the purchasing cost of the light helicopter, while despite constant technical and technological growth must not deviate from the standards of a category namely sport aircraft , which is increasingly moving away from the initial assumptions of accessibility and diffusion of flight.

Ranabot reconsiders accessibility of the sport rotor wing, while keeping purchasing costs in line with the category- being able to offer a new and evolved helicopter which only 6% more than the Charlie 2

IN THE HEAR OF THE CH77

We have chose the mast advance technology for the motor unit.

In a high-performance helicopter we must be able to get power without compromise.

For years we have chosen EPA POWER and have cooperating to the development of the propulsion unit .

For CH77 EPA POWER optimizes the Rotax 914 with complete disassembly from brand new and balancing of the motor shaft( using a unique EPA techniques and equipment ) to reduce vibration and improving sliding.
