This is the Alpha "Ryan Lutz Worlds Edition" 5+2 Port Competition .21 Engine. After nearly a year of refinement, the Ryan Lutz Worlds Edition Engine has arrived! After the success of the standard “Lutz Edition Engine”, Alpha Plus and Ryan Lutz have tuned and tweaked the 5 port design, taking it to the next level. The goals were to increase durability, drivability, and as always fuel mileage.
The first change is the Dynamic Equilibrium Crankshaft (DEC). The patented DEC design features a stronger crankpin that is much more resistant to wear. But the biggest innovation is the unique way Alpha Plus installed a brass weight into the silicone filling in the crankshaft. This helps to improve the balance of the crankshaft and produces a smoother running engine with increased fuel mileage and smoother drivability.
The next change is the Conrod. Machined from a more durable material, this rod is much more resistant to wear and tear. Finally, the crankcase features increased material, to improve strength, among other minor revisions to improve durability. The Alpha Plus “Ryan Lutz Worlds Edition Engine” takes nitro engine technology to the next level.
