We decided to show some of the components that we are installing into the VP engine on this and the following page. Due to the issues of protecting our intellectual property we will only show a few of the components used in the VPS, LLC engine in order to illustrate the difference in the quality between our parts and the stock parts that we removed from the original Rotorway engine.

Above the top set of timing gears are being installed into the VPS engine. The bottom set was removed from a stock Rotorway engine. Our timing gears are precision ground to true roundness so that they will not wear out prematurely as can be seen on the stock gears below after only 100 hours of use. This wear was caused by the stock gears not fitting together precisely.

One of the more expensive components in the VP engine is our proprietary connecting Rods. Our rods are engineered and manufactured by a major racing rod manufacturing company specifically for the VP engine.

The VP Connecting Rods are machined out of solid billet steel. They are then cyrogenically treated, shot peened to relieve stresses and then undergo several other processes to give virtually unlimited life.

On all of the rods that we removed from the stock engine, as on the cap shown above, the threads continue all the way through the casting as seen above. These threads form stress risers that could cause premature failures.

On the VPS connecting rod cap you can see the threads continue only to the portion of the rod cap at the end of the connecting rod bolt.

Notice the fit and finish of the mating surfaces of the rod removed from a stock Rotorway engine shown in the above photo.

Now compare the fit and finish of the stock connecting rod to the VPS connecting rod shown above as it is installed in the VPS, LLC engine. Also notice that the quality of the VPS connecting rod and cap is so precise that it is difficult to see where the rod and cap join.

In the above photo our engine designer and builder and lead A&P mechanic Andrew Burr is in the process of assembling one of our customer beta test engines. Each engine component is first blue-printed to insure that every component is fit to the exact engineering specifications before it is assembled. This blue-printing/assembly process takes several weeks to complete for each engine. Every specification is checked and close tollerance fitted to the nearest .0005". The VPS engine is not a mass produced powerplant. Every VPS engine is meticulously and precisely assembled piece by piece by our engine designer and FAA certified Airframe and Powerplant mechanic, Andrew Burr.
