Admit 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!
With the 120AX, there’s no need to buy an expensive aftermarket muffler!
The included Power Box comes with two adapters — one of which turns the muffler 90° to become a “Pitts style“.
With the 120AX and .91 side by side, you can see how they’re virtually identical in size — but you’ll enjoy a big difference in performance!
