Put more power in your .40-size model the easy way: just drop in a 55AX engine. It has the same bolt pattern as the 46AX for no-mod retrofits, but it also has the added displacement it needs to swing bigger props — and everything you need for better 3D, precision and sport flying.

Features:
Direct, bolt-in replacement for the 46AX.
A diagonally-placed needle offers more pilot safety and eliminates the need for a remote needle valve.
The 6-sided, angular head offers unique looks and significantly increases surface area for better cooling.

Recommended props: 11x6, 11x7, 12x6, 12x7, 12x8 & 13x6
