At its core, the Arc 46660-11100 excels in clarity and range, featuring a **broadband coverage** of 108.00 136.975 MHz for COM operations and 108.00 117.95 MHz for NAV (VOR/LOC), with an optional **GPS capability** for enhanced navigation accuracy. The unit incorporates **frequency synthesis technology**, ensuring stable and interference-free transmissions while minimizing drift, a critical factor in maintaining precise communication and navigation signals during flight. Its **solid-state construction** guarantees durability, resistance to environmental stressors, and long-term reliability, making it an ideal choice for both recreational and professional pilots who demand dependable performance in varying conditions.
The Arc 46660-11100 is equipped with **dual-conversion superheterodyne design**, which enhances signal processing and reduces noise, resulting in crisp audio output for both voice communications and navigation signals. Its **adjustable squelch control** allows pilots to fine-tune sensitivity, ensuring that only relevant transmissions are heard while minimizing background interference. Additionally, the unit supports **direct entry of frequencies**, simplifying the tuning process and reducing pilot workload during critical phases of flight. For added convenience, the radio includes **identification (ID) and test features**, enabling easy verification of proper operation and compliance with FAA regulations.
Installation of the Arc 46660-11100 is streamlined, thanks to its **direct plug-and-play compatibility** with the original Cessna wiring harness, ensuring minimal downtime and ease of upgrade. The unit adheres to **FAA certification standards**, including DO-160 environmental testing for vibration, temperature extremes, and humidity resistance, ensuring it can withstand the rigors of flight operations. Whether used in a single-engine piston aircraft, a light twin, or a high-performance trainer, this radio system provides the confidence and clarity pilots need to navigate safely and communicate effectively.
For those seeking an upgrade from aging or unreliable original equipment, the Arc 46660-11100 offers a **cost-effective, high-quality alternative** that maintains the legacy of Cessna s aviation heritage while incorporating modern advancements in radio technology. Its **compact yet robust design** ensures it fits seamlessly into existing cockpits, and its **long-term reliability** makes it a sound investment for aircraft owners looking to enhance their avionics without compromising on performance. With the Arc 46660-11100, pilots gain a trusted partner for both communication and navigation, ensuring every flight is conducted with precision and confidence.
### **Pros and Cons of buying a Cessna RT-385A Nav/Com Receiver-Transmitter (ARC 46660-11100)**
#### **Pros:**1. **High-Quality Performance** The RT-385A is a well-regarded aircraft radio designed for reliability and durability, making it suitable for both training and recreational flight. It operates on VHF frequencies, providing clear navigation (NAV) and communication (COM) capabilities.
2. **Compatibility with RC Aircraft** Since it is designed for radio-controlled aircraft, it integrates seamlessly with RC setups, allowing for realistic flight simulations and training. This makes it ideal for hobbyists who want to mimic real aviation equipment.
3. **Durability and Weather Resistance** Built to withstand the rigors of aviation environments, the RT-385A is likely constructed with materials that resist corrosion and electrical interference, ensuring long-term functionality.
4. **Easy Installation** As a plug-and-play unit, it can be installed relatively straightforwardly in an RC aircraft frame, reducing the complexity of wiring and setup compared to more advanced systems.
5. **Realistic Training Experience** For those involved in RC aviation training or simulation, this radio provides a more authentic experience by mimicking the controls and functionality of a real aircraft s NAV/COM system.
6. **Widely Available Parts and Support** Being a Cessna-branded component, replacement parts and technical support are likely easier to obtain compared to lesser-known brands.
7. **Frequency Coverage** The RT-385A covers standard VHF aviation bands, allowing for communication with other aircraft or ground stations (if equipped with compatible transmitters).
---
#### **Cons:**1. **Limited to RC Use Only** Unlike full-scale aviation radios, this unit is not designed for real aircraft. It lacks the power, certification, and regulatory compliance required for manned flight.
2. **No Real-World Certification** Since it is not FAA-approved or certified for actual aviation use, it cannot be used in real-world flight scenarios, even in experimental or ultralight aircraft without modifications.
3. **Potential for Interference** RC aircraft radios can be susceptible to interference from other electronic devices, especially in crowded frequency bands. This may require additional shielding or tuning for optimal performance.
4. **Cost Relative to Functionality** For hobbyists, the price of this radio may be higher than simpler, non-Cessna-branded RC radios that offer similar basic functionality. The brand premium might not justify the expense for casual users.
5. **Dependence on External Transmitters** The RT-385A is a receiver-transmitter, but it may still require an external transmitter (e.g., a ground station or another aircraft s radio) to fully utilize its communication capabilities. This adds complexity to setups.
6. **Limited Advanced Features** Unlike modern aviation radios, this unit may lack features such as GPS integration, digital tuning, or advanced navigation aids that are common in contemporary systems.
7. **Maintenance and Longevity Concerns** While durable, RC radios are not built for the same level of ruggedness as professional aviation equipment. Over time, wear and tear from repeated use in RC aircraft could lead to performance degradation.
8. **Learning Curve for Beginners** The RT-385A may be more complex for absolute beginners compared to simpler, all-in-one RC radios, requiring some familiarity with aviation radio protocols.
---
### **Conclusion:**The Cessna RT-385A Nav/Com receiver-transmitter is a high-quality, realistic option for hobbyists and enthusiasts who seek an authentic aviation experience in their RC aircraft. Its durability, brand reputation, and compatibility with RC setups make it a strong choice for those prioritizing performance and realism. However, its limitations such as lack of real-world certification, potential interference issues, and higher cost may not justify its purchase for casual users or those seeking simpler, more affordable alternatives.
For **serious RC pilots, aviation hobbyists, or those involved in flight simulation training**, the RT-385A is a worthwhile investment due to its reliability and professional-grade feel. For **beginners or those on a budget**, a more basic RC radio might suffice without the added complexity and expense.
### **Recommendation:**- **Buy if:** You are an experienced RC pilot, involved in flight simulation, or prioritize a realistic aviation experience in your RC aircraft. The RT-385A s durability and brand reputation make it a solid long-term choice.
- **Avoid if:** You are a beginner, seeking a budget-friendly option, or plan to use the radio in a non-aviation context where simpler alternatives would suffice. In such cases, consider more affordable RC radios with comparable basic functionality.
