Up for auction is a used Magnum XLS.46A 2-Stroke R/C Engine W/Muffler. The carb on this engine was swapped out for an OS 40K carb and then broken-in using 10% nitro with 20% castor oil. Three 8 ounce tanks total were run through it during the break-in. The OS carb was a HUGE boost to the power of the engine and it ran smooth as silk using an 11x6 prop. This definitely is a "sleeper" engine and would be great for any .40 size plane. Glow plug, muffler and instructions are included but the original carb is not. If you never run a Magnum engine with an OS carb on it....here's your chance! A great running engine!!!! Shipping to North America only.
