ℝ𝕆𝕋𝕆 𝟙𝟚𝟝 𝔽𝕊 𝔽𝕣𝕠𝕟𝕥 ℂ𝕒𝕣𝕓𝕦𝕣𝕖𝕥𝕠𝕣 💫

The new rc plane scale engine Roto 125 FS is completely maintenance-free, has high performance and is also suitable for use in aircraft such as the towing machine.

Our developers have managed to tune the engine for the use of propellers with a large pitch to achieve a realistic sound, and therefore we recommend for the Roto 125 FS engine a propeller with a pitch of 14 "Propeller diameters are from 28" to 30 "for two blade propellers.

The maximum engine power is up to 6 kW.

A unique novelty on Roto 125 FS engines is the factory-installed carburetor control. To control the throttle, we chose the Savox SV-1232MG servo, which is verified in practice on our UAV projects.

The reason for this improvement is to make it easier for customers to install the engine on an aircraft. With the bottom suction feature and factory-installed carburetor control, customers can simply connect the servo to the receiver and set the servo deflection. They don't have to deal with servo levers or drawbars, everything is original from Roto.

ℝ𝕆𝕋𝕆 𝟙𝟚𝟝 𝔽𝕊𝕀 💥

The Roto 125 FSi is a new engine for inline engine aircraft. The design of the engine was aimed at easy installation in an aircraft with a narrow fuselage. Engine performance is comparable to 125cc four-stroke engines, low idle and easy starting is a given.

The engine has been developed with all the experience provided from the Roto - UAV development group and meets the highest possible standards of production quality and output testing.

The Roto 125 FSi is a twin cylinder, four stroke, air cooled inline engine with a single carburettor for ease of user setup. The engine is completely built on roller bearings and is completely maintenance free. Engine lubrication is provided by a system adopted from Roto - UAV and no relubrication is required. The valves and their gears are developed so that their inspection is not necessary before 40 hours of operation.

Introducing a new starting system for Roto engines called RSS Roto Start System.

It is a very lightweight yet reliable remote engine starting system using RC transmitter ( PWM command ).

The design is based on a unidirectional special bearing and several gears to ensure an optimal gear ratio from the BLDC starter motor.

The starter can be powered by 2-4 LiXX batteries with normal current load.

The system is designed to serve reliably for the lifetime of the internal combustion engine in RC operation configuration.

ROTO 85 FSI 270 - The 270° crankshaft is used exclusively for Warbirds.

The sound of this engine is enhanced by this specially designed crankshaft design specifically for use in WWII fighter aircraft.

The long awaited increase in engine power, by changing the camshaft timing, is also a big change. Another new feature is the use of two carburettors, which take care of separate cylinder filling.
