<p><strong>Plentiful power for sport and aerobatic aircraft!</strong></p> <p>Ease, dependability and performance are what make engines popular - and they're also three good reasons why the 46AXII has become an instant flyer favorite. Lightweight and low maintenance, the 46AXII is as good a choice for easy sport flying as hard-charging aerobatics. An extension cable and an angled high-speed needle make fine-tuned performance and maximum personal safety easy to enjoy.</p> <ul> <li>Simple, side-exhaust design.</li> <li>Power Box muffler features a squared-off shape for easier fits in more cowls.</li> <li>40K carburetor has high- and low-speed needles, plus a mixture adjustment screw. Tighter tolerances between the piston and ABL create a tighter compression seal and improved power.</li> <li>Dual ball bearing-supported crankshaft lowers friction and wear.</li> <li>Head automatically centers and levels itself - and snugs down with just 4 screws.</li> <li>Subtly tapered low-end needle eliminates surging at transition, ensuring smooth,<br />controllable power across the rpm range.</li> <li>Updated liner ports and a ball-milled inlet port minimize turbulence and promote better fuel/air mixing.</li> <li>Minimizes "creep" and resets with seals on both needles and a ratchet spring on the high-speed needle. A rotor guide screw eliminates spring-related movement, too.</li> <li>Includes a lock nut and a longer crankshaft with more thread length to ensure better<br />prop nut engagement and greater pilot safety.</li> <li>Includes glow plug, muffler, cable extension and warranty.</li> <li>The ABL (Advanced Bi-Metallic Liner) includes one layer for better bonding, and another to reduce wear and extend life.</li> <li>A needle-valve extension cable and rear-angled high-speed needle maximum pilot safety and convenience.</li> <li>A generously sized chamber and larger sound baffle help the Power Box muffler significantly reduce exhaust noise without compromising power. Rotatable exhaust outlet provides effective, no-cost finish protection.</li> </ul> <p><strong>Requires:</strong></p> <ul> <li>Glow fuel containing 5-20% nitromethane content and at least 16% lubricant content</li> <li>Propeller (10.5x6, 11x6-8, 12x6-7 are recommended; use 10x6 for break-in)</li> </ul> <p><strong>Specifications:</strong></p> <ul> <li>Displacement: 0.455 cu in (7.45 cc)</li> <li>Bore: 0.886 in (22 mm)</li> <li>Stroke: 0.772 in (19.6 mm)</li> <li>RPM Range: 2000-17000</li> <li>Output: 1.63 hp @ 16000 rpm</li> <li>Weight w/Muffler: 17.1 oz (486 g)</li> <li>Engine: 13.3 oz (378 g)</li> <li>Muffler: 3.8 oz (108 g)</li> <li>Suggested Propellers: 10.5x6, 11x6, 11x7, 11x8, 12x6 & 12x7</li> <li>Break-in Propeller: 10 x 6</li> </ul>
