The **67166/52-37 Ultralight Wood Propeller** is a meticulously crafted, high-performance propeller designed for ultralight aircraft, sport planes, and light general aviation applications, offering an optimal balance of efficiency, durability, and ease of maintenance. Engineered with precision, this **52-inch diameter propeller** features a **37-inch pitch**, making it an ideal choice for engines ranging from 80 to 160 horsepower, including popular models like the Rotax 912, 914, and 135 series, as well as Lycoming and Continental engines in the 80 125 hp range. The **67166** designation indicates a **two-blade, fixed-pitch design** with a **67-degree blade angle**, which enhances climb performance and cruising efficiency while maintaining smooth operation across a broad RPM range.

Constructed from **high-quality, lightweight hardwood** typically ash or maple this propeller is built to withstand the demands of high-speed flight and repeated takeoffs and landings without compromising structural integrity. The **52-hole shank** allows for precise balancing and easy installation, ensuring optimal engine performance and reduced vibration. Each blade is meticulously shaped with a **hydrodynamic airfoil profile**, featuring a **thin, aerodynamic leading edge** and a **smooth, tapered trailing edge** to minimize drag and maximize thrust efficiency. The **wood core** is reinforced with **epoxy resin and fiberglass**, providing exceptional strength-to-weight ratios while resisting moisture, warping, and fatigue over extended use.

One of the standout features of this propeller is its **ultralight-specific design**, which prioritizes **low weight without sacrificing performance**. The **lightweight construction** reduces inertia, allowing for quicker engine response and improved throttle control, particularly beneficial in high-performance and aerobatic applications. Additionally, the **fixed-pitch design** eliminates the need for complex variable-pitch mechanisms, simplifying maintenance and reducing potential points of failure. This propeller is also **easily repairable**, as damaged blades can be sanded, reshaped, and rebalanced on-site, making it a cost-effective solution for pilots who value both performance and practicality.

Safety and reliability are paramount in aviation, and this propeller delivers on both fronts. The **balanced shank** ensures minimal vibration during operation, contributing to a smoother ride and reduced wear on the engine and airframe. The **durable construction** means it can endure the rigors of frequent flights, including short takeoffs, steep climbs, and high-speed maneuvers, without losing structural integrity. Whether used in a **homebuilt ultralight, a high-wing trainer, or a light sport aircraft**, this propeller provides the **efficiency needed for fuel savings** and the **responsiveness required for agile flight**.

For pilots who demand **performance without complexity**, the **67166/52-37 Ultralight Wood Propeller** is an excellent choice. Its **proven design**, **lightweight build**, and **ease of maintenance** make it a favorite among general aviation enthusiasts, flight instructors, and aerobatic pilots alike. Whether you're looking to optimize climb rates, improve cruise efficiency, or simply ensure a reliable propeller for your next adventure, this **high-quality, handcrafted propeller** delivers the precision and durability needed to keep your aircraft performing at its best.

### **Pros and Cons of buying a Ultralight 67166/52-37 Wood Propeller (52-Hole Pattern)**

1. **Performance and Efficiency** Wood propellers are known for their aerodynamic efficiency, especially in high-performance aircraft. The 67166/52-37 design is optimized for speed and climb performance, making it suitable for ultralight and light sport aircraft.

2. **Lightweight** Wood propellers are generally lighter than metal counterparts, reducing overall aircraft weight, which can improve fuel efficiency and maneuverability.

3. **Durability in Certain Conditions** Wood propellers can handle minor impacts better than some metal propellers, as they are less prone to cracking under light stress (though they are not immune to damage).

4. **Cost-Effective for Some Applications** Compared to high-end metal propellers, wood propellers can be more affordable, especially for hobbyists or those operating on tight budgets.

5. **Customizability** Wood propellers can sometimes be repaired or modified more easily than metal ones, though this depends on expertise.

6. **Aesthetic Appeal** Many pilots appreciate the classic look of wood propellers, which can be a personal preference for vintage or custom aircraft.

7. **Good for Low-Speed Flight** The design is well-suited for ultralight and slow-flying aircraft where metal propellers might be overkill.

1. **Maintenance Requirements** Wood propellers require regular inspection for cracks, delamination, or moisture damage. They must be protected from water exposure and UV degradation.

2. **Limited Lifespan** Unlike metal propellers, wood propellers degrade over time due to environmental factors (humidity, temperature fluctuations) and wear. They typically need replacement more frequently than high-quality metal propellers.

3. **Sensitivity to Impact Damage** While wood can absorb minor shocks, severe impacts (e.g., bird strikes, ground contact) can cause hidden internal damage that isn t immediately visible, leading to catastrophic failure if not detected.

4. **Lower Strength in Extreme Conditions** Wood propellers are not as strong as metal propellers under high stress, such as sudden power changes or high-speed flight in turbulent conditions.

5. **Repair Difficulty** While some repairs are possible, advanced woodworking skills and proper materials (e.g., epoxy, fiberglass) are often required. Poor repairs can compromise safety.

6. **Limited Availability of Experts** Finding qualified technicians to inspect, repair, or replace wood propellers can be challenging compared to metal propellers.

7. **Not Ideal for High-Horsepower Engines** The 52-inch diameter and 37-inch pitch may not be optimal for high-power setups, where metal propellers with better stress resistance are often preferred.

8. **Environmental Sensitivity** Wood propellers must be stored properly (e.g., in dry conditions) to prevent warping or mold growth.

The **Ultralight 67166/52-37 wood propeller** is a viable choice for pilots operating ultralight or light sport aircraft where weight savings and aerodynamic efficiency are priorities. It excels in low-speed, leisure, or training applications where durability is not the primary concern. However, its maintenance demands, limited lifespan, and susceptibility to damage make it less ideal for high-performance, high-stress, or commercial operations.

For pilots who prioritize **cost efficiency, lightweight operation, and classic aesthetics** while being willing to invest time in maintenance, this propeller is a solid option. For those seeking **long-term reliability, high-stress performance, or ease of repair**, a metal propeller (e.g., McCauley, Hartzell, or Warp Drive) would likely be a better investment.

---

- You operate an ultralight or light sport aircraft with moderate power.

- You are willing to perform regular inspections and maintenance.

- You prefer the weight savings and aerodynamic benefits over metal alternatives.

- Your flying conditions are mostly smooth and low-stress.

- You fly frequently in turbulent or high-stress conditions.

- You lack experience in wood propeller maintenance.

- You operate a high-performance or high-horsepower aircraft.

- You prioritize long-term durability and minimal upkeep.

For most serious pilots, a **high-quality metal propeller** (e.g., a 52x37 McCauley or Warp Drive) would offer better longevity and safety, but the wood option remains a practical choice for specific applications. Always consult your aircraft manufacturer or a certified propeller specialist before making a decision.
