Why Choose the EN-P40 40kgf RC Turbine Engine
1️⃣ Precision Engineering for Reliable Performance
Every EN-P40 engine is meticulously engineered with aerospace-grade alloys, precision-balanced compressor wheels, and a brushless electric starter system. The result is consistent thrust output, reduced vibration, and extended service life — crucial for civil model jets and professional UAV platforms that demand both stability and safety.
Its smart ECU (Electronic Control Unit) offers automatic start sequences, real-time monitoring, and adaptive throttle response, ensuring seamless control during all flight conditions.
2️⃣ Optimized Power-to-Weight Ratio
Weighing only around 4.5 kg while generating a maximum thrust of 40 kgf, the EN-P40 is one of the most efficient miniature turbine engines in its category. The engine’s compact form factor (Ø148 mm × 390 mm) allows for flexible installation even in space-limited fuselages — making it an ideal choice for sport jets, aerobatic RC aircraft, and light UAV systems.
This superior power-to-weight ratio gives pilots a responsive, high-speed flight experience without compromising fuel efficiency or payload capacity.
3️⃣ Fuel Efficiency & Low Emissions
The EN-P40 uses Jet A-1 or Kerosene, offering excellent thermal stability and combustion efficiency. Its advanced fuel injection system precisely manages air–fuel ratios to minimize waste and emissions.
This not only extends flight endurance but also helps maintain clean turbine operation — a major advantage for operators running multiple sorties or using engines for research and testing.
4️⃣ Advanced Control & ECU System
Energy-RCJetEngine’s proprietary digital ECU features auto-start, shutdown protection, data logging, and telemetry support via RS232/RS422 communication. Pilots and technicians can easily monitor parameters like:
-
Thrust output
-
RPM speed
-
Exhaust gas temperature (EGT)
-
Fuel flow rate
-
System voltage and current
The ECU’s smart algorithms optimize startup performance and reduce operator workload — a perfect fit for both experienced RC pilots and professional UAV engineers.
