ROTO 85cc FS Inline engine with Starter/E-Controller GST Inc (AUS Warehouse)

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

for hobby industry, modellers only need the version with starter/generator (carby version) Config 85D 

• 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
