Regarding Roto Motor 85cc FS UAV engine (Production & Testing around 20 days)

• There are up to 18 configurations for different solutions.
• The engine has carby version and EFI (Electronic Fuel Injection)
• There are two generator in 400W and 1000W and Voltage regulator in two voltage outputs

Rotomotor makes one key starter (STG/Starter) and EPU (Electric Power Unit)/generator in 1000W and 2000W

STG-EPU (Start Generator-Electric Power Unit)

Rotomotor makes E-Control which Is designed to remote starter, turbo mode, charge and use battery from 12S Lipo battery for the project (servo, RX, camera Gimbal, task payload etc). This is the best solution to integrate other gears (One Key starter/EPU) for long endurance and battery life time circle. It is very useful for both carby version and EFi version

E-Control is an electronic system designed to control the motor generator, which allows the start of the internal combustion engine, charging batteries and hybrid operation, increasing the power of the internal combustion engine

BMS (Battery Management System) is used for battery lifetime maintenance, which use Lipo, Li-ion, LifePO4 cells or other cells with operation voltage range 1.8V-5V each cell. BMS provides protection and increase the lifetime of the batteries by measuring its temperature, controlling the voltage and flowed current.

Configuration explanation:

If the customer wants to achieve up to 5000 meter altitude and long endurance and long life time of the battery, select Config 85E or F

For 85cc EFI version, Engine Management (EngManager) package with control Module/Panel is optional and supplied, which is designed to manage and control petrol engine from one central injector to four sequential injectors, which the flight control display, input voltage, engine temperature,RPM, timer, fuel level info, Fuel flow info, Altitude correction, injection delay, automatic choke/temperture choke at cold engine start, fue tank volume, fuel indicator calibration/cosumption, fuel pump etc can be adjusted.

The engine management package does not need to be connected to a PC, which is often difficult when running the engine on site. It is optional. This package is not necessary unless the customer wants precision settings.

EngManager includes Main unit, injector, fuel pump, fuel filter, 2pcs CHT sensors, main cable connector, Oxygen sensor, controler for oxygen sensor, Glavanic separation module for ignition, control module, and flight control display.

ROTO 85 FS AL is suitable for UAV projects within the range of 4 meters and weight up to 35 kg.
