Mattes Engine Rework specializes in modifications and repair of Nostalgia and Vintage engines for Free Flight and Control Line model airplane events. Rework is also performed on current production engines for non-throttle use. A major modification is making heads for engines to improve glow plug durability and performance using the vertical coil Nelson plug. Other work performed is summarized on the Engine Rework Summary (Hop-Up) page and described in detail on associated description pages.
A Nelson Head has been developed that replaces the stock Cox Glow Head on the Cox 0.020 engine. This head uses the unique flat coil Nelson plug and has provided superior performance and outstanding durability. Replacement glow plugs are significantly lower cost and more available than the Cox 0.020 head.
This site provides an overview of the engine rework performed by Bob Mattes, that’s me, in my shop. I have been flying models on and off since I was about 10 years old changing from control line to free flight during my years at college. Worked at McDonnell Douglas, now a part of Boeing, and finally retired in 1999 at which time I reentered Free Flight big time in some of the power events. Started working on AMA Power engines and Nostalgia engines to improve performance leading to this little venture which helps keep me busy. I am a member of the AMA, NFFS, SAM, and MECA.
I have chaired the NFFS Competition Committee and the National Cup Rules/Scoring Committee for the past few years. In October of recent years I have been organizing and CDing a contest at the Lawrenceville Airport located on US 50 between Lawrenceville, IL and Vincennes, IN. This year, 2010, the contest is on October 16 and 17. A flier is included on this web site and you all are welcome to attend the contest.
