125cc FS Twin Engine With Starter

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.

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, just connect the servo to the receiver and set the servo deflection. The customer does not have to deal with servo levers or drawbars, everything is original from Roto.
