What the industry has

been waiting for, a

significant leap forward

in unmanned systems

engine performance and

reliability. The compact

design of this system

makes it a perfect choice

for integration into small

UAV platforms. The

robust engine control

capabilities are perfectly

suited for use in the UAV

industry.

Reduce the time to Successful Flight

Cloud Cap Technology offers complete turnkeyEFI solutions for UAV powerplants.

In partnership with industry leaders, the STRATUS

family of powertrain solutions provides a completeoff-the-shelf system including core engine,Electronic Fuel Injection (EFI), Engine Control Unit(ECU), vibration isolation mount, propeller andgenerator.

Our EFI solutions are the key to increasing fuelefficiency, improving engine efficiency, reducingmaintenance, and reducing costly engine failures.By increasing reliability, fuel efficiency and thesystems performance envelope, total systemendurance and performance increases while totalcost of ownership decreases.

Cloud Cap can also provide custom enginecontrol systems and hardware configured for yourspecific application.

- Full integration services and engineeringsupport

- Seamless Piccolo autopilot compatibility

- In-house calibration across the entireperformance envelope (not only the prop curve)

- ECU using proven automotive-qualityprocessors and algorithms

- Positive displacement high performance self-priming fuel pumps

- Intake manifolds and throttle bodies

- All required harnessing, sensors, and injectors

Lower Fuel Consumption

Small engine carburetors deliver an excessivefuel-to-air-ratio at both low power output andat high power output making effective altitude

compensation difficult to achieve. EFI allowsthe proper air/fuel ratio to be maintained withaltitude and other changing air density conditions.Depending on the engine expect a 15% to 30%reduction in fuel usage in both two and four strokeengines when converting from carburetor to EFI.

Improved Starting Performance

The EFI system can calculate the optimum air/fuel mixture for starting in all conditions. Thepressurized fuel system and fuel injector providesuperior fuel atomization at colder temperatures.

EFI mitigates the need for the user to makecarburetor adjustments that can later adverselyaffect flight behavior.

Improved Engine Reliability and Durability

EFI control systems maintain optimum air/fuel ratios during all phases of operation. Thisreduces the number of random engine outagesand prolongs engine life reducing costly enginemaintenance, and significantly increasing theMTBF/MTBR (Mean-Time Between Failures/Mean-Time Between Repairs or Replacements).

Maintain Peak Power and Better Fuel

Economy

Because EFI maintains proper air/fuel ratio underall conditions, peak power can be maintained

while also improving fuel economy.

Expanded Engine Performance Envelope

Since the ECU can automatically adjust the fuelingfor ambient pressure changes EFI engines canoperate effectively at sea-level or in the mountainswithout having to be re-tuned or adjusted. Thisfunction is required to reduce the power lapse ofthe engine at higher altitudes. Less power lapsemeans a higher altitude envelope.

Engine Data Collection

Onboard data logging comes with each ECU.The ECU logging feature is fully user configurablefor channels and data rate as well as trigger and

overwrite settings.

Plug and Play Operation with Avionics

STRATUS EFI systems are easily integrated withthe Cloud Cap Technology family of Piccoloavionics. In addition, through the open and fullydocumented API and the CANbus interface, theSTRATUS EFI system can be readily integratedwith other avionics.

Cloud Cap offers more than EFI we

offer everything you need to elevate

your hobby-grade engine to a fully

integrated purpose built power plant

solution.
