The nitro version Nimbus 550 comes stock with a new upper swash plate to remove unequal cyclic and collective differential. Longer outer swash plate balls are also included to improve servo to swash plate geometry; combined with the new uoper swash plate this keens the same good control ratio proven on the Nimbus 550 electric.

The original Nimbus cyclic and collective range has been proven to work with many flight control systems. Now the rotor head keeps the same proven ratio but has no linkage differential further improving the flight feel and making bench setup easier.

The Nimbus 550 Nitro features a proven tapered clutch system adopted from the Nitro 700, making it the smoothest and easiest-to-align clutch stack available on the market.

The core of the airframe consists of a single-piece 7075 aluminum bearing block assembly and servo mount, which provides rigidity to the frame and drivetrain. The cyclic servos are arranged in a 120-degree layout for optimal control geometry.

The parts are easily removed using simple tools included in the kit. including a crank lock, clutch liner gap tool, and heavy duty Allen keys for the special tapered parts.Engine maintenance is also easy, with the ability to remove the engine from the bottom without disturbing other assemblies in a matter of minutes. The engine cooling fan shroud can be independently removed by side and without disassembly of otherparts.

With a 7.7 gear ratio, it is perfectly matched to achieve a good rotor RPM while providing enough torque for demanding maneuvers with 550-580mm blades. Optional parts are available to stretch it to a 650-Size with an 8.5 gear ratio. The main gear directly drives the head and has been designed to efficiently transmit rotor torque, producing peak power through extreme rigidity.
