Perfect for 3D, precision and sport flying!
It's the "no mod" way to ratchet up horsepower for more flying fun! The 120AX fits in the same space as a .91 — while boasting 20% more displacement. That means it can turn bigger props with ease, resulting in improved 3D, precision and sport flying. Boost your plane's performance, without compromising weight or mounting space — bolt in a 120AX and see the difference for yourself!
Delivers 20% more power than a .91, and with new CCD technology will bolt right where the .91 used to be.
At 21 ounces, the 120AX is a very minimal weight increase over a .91.
The new angular head design not only looks great, it significantly increases surface area for better heat transfer.
