The MAX-11AX Limited Edition by OS Engine is a strong choice for advanced flyers and collectors who want a small, high-revving engine with a unique provenance. Its solid design and usable RPM band make it easy to tune for precise flight behaviour.

The MAX-11AX performs best in experienced hands due to its high RPM range and tuning needs; beginners can use it but should seek guidance on setup and break-in.
Prop selection depends on the airframe, but for 10 Class planes try common sport or scale props in the recommended diameter and pitch ranges and adjust for peak RPM around 15,000rpm.
Follow a staged break-in with richer needle settings, short runs at varying loads, and regular inspections. Use quality fuel and a suitable glow plug to ensure a proper seating of components.
