CubCrafters Upgrades Rotax 916 iS Engine with FADEC System

CubCrafters Introduces FADEC Software Upgrade for Rotax 916 iS Engine
CubCrafters has announced a significant enhancement to its aircraft powered by the Rotax 916 iS engine through the introduction of a Full Authority Digital Engine Control (FADEC) software upgrade. Developed in collaboration with Red Bull Air Race and STOL pilot Luke Czepiela, alongside RS Flight Systems, the upgrade aims to improve engine performance while maintaining the simplicity and reliability that the Rotax 916 iS is known for. The new software promises noticeable gains in acceleration, climb rates, and cruise efficiency without requiring any hardware modifications.
Development and Performance Enhancements
Luke Czepiela, recognized for his daring aviation exploits—including the notable Bullseye Landing on Dubai’s Burj Al Arab helipad in a customized Carbon Cub—leveraged his extensive experience flying Carbon Cubs in demanding conditions to help fine-tune the engine management software. CubCrafters reports that the upgrade results in a more responsive and enjoyable flying experience across the entire flight envelope. Pilots can expect faster acceleration during takeoff and go-arounds, improved climb performance, higher cruise speeds, as well as enhanced deceleration and energy management.
Unlike conventional performance upgrades that often necessitate physical alterations to the engine or aircraft, this FADEC enhancement is delivered entirely through software. This approach simplifies installation, reduces aircraft downtime, and has been successfully tested on CubCrafters models equipped with both Hartzell and MT propellers. The upgrade is now available for eligible Rotax 916 iS-powered aircraft at a cost of $1,500.
Brad Damm, Vice President of CubCrafters, emphasized the value of Czepiela’s input, stating, “Luke has accumulated thousands of hours operating Carbon Cub aircraft in some of the most demanding flying environments imaginable. His deep understanding of the aircraft, combined with the engineering expertise of RS Flight Systems, has resulted in a software enhancement that makes an already remarkable airplane even more responsive and capable. Pilots will notice the difference from the moment they advance the throttle.” Czepiela added, “The Rotax 916 iS is already an incredible engine, but we saw opportunities to further optimize how it delivers power throughout the flight envelope. The goal wasn’t simply to increase performance on paper. We wanted to make the aircraft feel more responsive and enjoyable to fly.”
Industry Implications and Market Reception
The integration of a FADEC system into the Rotax 916 iS platform represents a notable advancement for CubCrafters, reflecting broader trends toward digital engine management in light aircraft. Achieving seamless integration and ensuring reliability required extensive testing and validation. Early responses from the market indicate strong interest among buyers seeking advanced and efficient engine technologies, which may bolster CubCrafters’ sales prospects.
This development could also prompt competitors such as Lycoming and Continental to accelerate their own efforts in digital engine control systems, potentially intensifying competition within the light aircraft engine sector. As manufacturers strive to deliver more sophisticated and efficient propulsion solutions, pilots and operators stand to benefit from continued innovation.
The Rotax 916 iS Performance Software Upgrade is available immediately. Further details can be found at CubCrafters.com.
