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.Simple, side-exhaust design.Power Box muffler features a squared-off shape for easier fits in more cowls.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.Dual ball bearing-supported crankshaft lowers friction and wear.Head automatically centers and levels itself — and snugs down with just 4 screws.Subtly tapered low-end needle eliminates surging at transition, ensuring smooth,controllable power across the rpm range.Updated liner ports and a ball-milled inlet port minimize turbulence and promote better fuel/air mixing.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.Includes a lock nut and a longer crankshaft with more thread length to ensure betterprop nut engagement and greater pilot safety.Includes glow plug, muffler, cable extension and warranty.The ABL (Advanced Bi-Metallic Liner) includes one layer for better bonding, and another to reduce wear and extend life.A needle-valve extension cable and rear-angled high-speed needle maximum pilot safety and convenience.A generously sized chamber and larger sound baffle help the Power Box muffler significantly reduce exhaust noise without compromising power.

Typically it sells for approx. $20/gallon. There are gas engines made for hobby aircraft and they would require 2 stroke fuel such as you describe......this engine is not one of them. **Q: can this engine work wih the normal 2 stroke gas as a weedwacker would use?** A: No this engine must run on a 2 stoke nitromethane based fuel **Q: Is this engine ready to run. If hoses connected from the glow fuel tank and is a full starter** A: Engine is ready to run, but you must break it in. Just hook up the lines, prime it by cranking with your finger over the exhaust and fire it up. **Q: Will this work in a truck also. Like for say a traxxes TMaxx 1/10 replacement for a 3.3** A: Not the right application for this engine. This one is designed for aircraft. Go to the O.S. website and you will find several models for car and buggy use. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Engine *by S***R on November 1, 2023* Fast delivery, great running motor. ### ⭐⭐⭐⭐⭐ THIS IS ONE GREAT ENGINE! *by B***G on June 5, 2018* I'm a big fan of all O.S. engines and have several.
