O.S. 120AX Engines

O.S. 120AX

Perfect for 3D, precision and sport flying!


O.S. Two Year WarrantyAdmit it: if you could ratchet up horsepower without having to increase the mounting space, you’d probably jump at the chance. Well, here it is. The 120AX boasts 25% more displacement than a .91 (think of the bigger props you can swing!) — and bolts into the same space, with almost no extra weight.
And that’s not all. The 120AX’s innovative Power Box muffler offers mounting versatility that translates into value. Plus, the angled heat sink head not only looks sharp, it adds more surface area, for better cooling. Here's a golden opportunity to boost your airplane's flying capabilities — with almost no modification!
