Perfect for 3D, precision and sport flying!

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. Here’s a golden opportunity to boost your airplane's flying capabilities — with almost no modification!
  • Model Application: Ideal for 3D, Precision and Sport flying
  • Mounting Application: Mounts in same space as the .91FX
  • Construction: Steel piston ring and liner, aluminum piston
  • Carburetor: 70D with rearward angled needle valve for safety
  • Glowplug: O.S. #8 supplied with engine, A5 (OSMG2693) will also work
