But Castle Creations is back with a vengeance, introducing the Hydra XLX 2, a speed control that’s been proven reliable in the car world. Let’s take a closer look at what makes it stand out.

Key Specifications

The Hydra XLX 2 ESC boasts impressive specifications. It offers a continuous current rating of 180 amps and a burst current rating of 350 amps, making it suitable for high-powered setups. But what sets Castle Creations apart is their transparency. Unlike many other ESC manufacturers, Castle provides amperage ratings AND an explanation of the standard used to obtain this rating. From my point of view with the RC Car version of the XLX2, these current values are conservative. With conservative current specifications, transparency and an understanding of how these values are obtained, it sure ensures us that we can trust the reliability and performance of their ESCs.

Continuous vs. Burst Current

Understanding the difference between continuous and burst current is crucial. The continuous current rating of 180 amps is sustainable for five minutes with proper cooling, connectors, and batteries. Using inadequately sized components can stress the ESC and lead to failure, which is not covered by warranty. The burst current rating of 350 amps, on the other hand, is for short, momentary periods lasting no more than two seconds. Knowing these limits helps you use your components optimally and avoid overloading your ESC.

Managing Ripple Voltage

One of the key factors affecting ESC reliability is ripple voltage. This phenomenon can be problematic if not managed correctly. Castle Creations addresses this issue by providing data logs that show the performance of their ESCs. In a data log from a run with the RC Car version of the XLX 2, we can see that the voltage of the battery drops significantly during high-power bursts. This is also at a current draw in excess of 300A, meaning the Castle XLX 2 has excellent ripple voltage management. We calculated the ripple voltage to be 4.4%, which is below the 5% threshold or the starting range of when one should think about using a capacitor pack to mitigate ripple voltage.

Conclusion

In conclusion, Castle Creations’ return to the boat market with the Hydra XLX 2 ESC is a significant step forward. With their commitment to transparency and clear amperage ratings with an explanation of how they were determined, you can trust the reliability and performance of their ESCs.

Shocking truth of the Wye vs Delta Brushless Motor Wind

Today we’re diving deep into the fascinating world of RC brushless motors, specifically exploring the intriguing differences between Y-Wind and Delta-Wind configurations. If you’re an RC hobbyist, understanding these distinctions can be crucial in optimizing your motor selection for your unique applications. So, let’s uncover the truth behind these motors and which one might be the right choice for you.

Wye vs Delta Brushless Motor Wind

Understanding the Basics

First and foremost, let’s address the fundamental concept behind these motor types and their impact on RC hobbyists. To provide a fair comparison, we’ll consider motors of equal size. When we wind a motor with a Delta configuration and give it one turn of wire, we’ll immediately notice a significant difference: a higher Kv value. This higher Kv value means that a Delta-Wind motor can draw more current. However, there’s a trade-off. A higher Kv motor can’t handle as much voltage. So, you get more current but sacrifice potential voltage.

On the other hand, the Y-Wind motor will have a lower Kv, meaning it draws less current but can handle a higher voltage. When you multiply the voltage and current, you get the wattage value. Surprisingly, when you compare the wattage values of both Y-Wind and Delta-Wind motors of the same size, you’ll find that they have identical power potential. It’s a balancing act between current and voltage.

In the image above, you can note that the Delta wind has only one coil between any two of the connectors A through C. The Wye wind on the other hand, contains two coils between any 2 connectors A through C. This is where the electrical difference comes from.

Choosing the Right Motor

Now, the big question arises: which motor should you choose? Y-Wind or Delta-Wind? The truth is that for most RC hobbyists, it doesn’t matter. Both motor types offer virtually identical performance. The subtle differences, however, are worth exploring.

When it comes to motor selection, the key factors to consider are the Kv value and the desired power output for your specific application. These factors far outweigh the choice between Y-Wind and Delta-Wind configurations. Motor manufacturers offer both options to cater to a wide range of preferences and applications, primarily focusing on different Kv values for the same motor size.

Wye vs Delta Subtle Difference

One subtle difference worth mentioning relates to timing. Y-Wind motors tend to perform best with the lowest possible timing setting. Increasing the timing may boost RPM but at the expense of generating excess heat. In contrast, Delta-Wind motors prefer minimal timing adjustments, leaving little room for timing advancement. If you’re seeking higher RPM from a motor, it’s advisable to consider a different Kv motor altogether.

Final Thoughts

In conclusion, the choice between Y-Wind and Delta-Wind motors should primarily depend on your specific Kv and power output requirements. The select the wind that makes the most sense regardless if you end up with a Wye or Delta wind for that specific motor Kv. Don’t get caught up in the intricacies of motor winding configurations. Focus on selecting the right motor for your needs, and from there, fine-tune your RC experience based on your application and performance preferences.

We hope this article has shed light on the truth behind RC brushless motors and their winding configurations. Remember, the key to success in the RC world lies in making informed choices that suit your unique needs.

Pre-Flight RC Airplane Checklists

As with any aircraft, it is crucial to perform a pre-flight checklist before operating an RC airplane. Some may describe the checklist as one of the most important steps for a successful flight. Although it may seem tedious, completing a thorough pre-flight inspection can prevent accidents, prolong the life of your aircraft, and improve your overall flying experience. In this article, we will cover the essential items to include in your pre-flight RC airplane checklist. Let’s get started with number one on our list

1. Battery Check

First and foremost, you should check the battery life of your RC airplane. Make sure your battery is fully charged before flying. A low battery can cause your aircraft to lose power mid-flight, leading to a crash. Or even as, I’ve seen in the past with an electric jet, not even one circuit of the airfield. Before I take off for every flight I measure the voltage with a battery checker prior to locking the canopy. This check goes a long way. I’d highly recommend following this item if there is anything that you take away from this list.

2. Control Surface Check

Next, inspect each control surface to ensure that they are operating correctly. Check the hinges, control horns, and linkages for any signs of damage or wear. Verify that each control surface moves freely and that it is not binding. Ensure that the control surfaces are moving in the correct direction based on your radio transmitter input. I would recommend placing a small load on each control surface to truly verify if the servos are in good working condition. 

3. Radio and Control Surface Direction Check

The radio system is the primary way to control your RC airplane. Before takeoff, make sure that your transmitter is functioning correctly. Test each control surface to ensure that they move in the correct direction and that the response time is satisfactory. Check the radio receiver on your aircraft, ensuring that it is securely mounted and that all of the antenna wires are intact. This check will only be practical if you can visually see the antenna in its currently installed location. Oh, and don’t forget to check your flight time timer to ensure it has been reset correctly. 

4. Motor and Propeller Check

The motor and propeller are critical components of your RC airplane. Ensure that the motor is securely mounted, and that the propeller is tight and free from any damage. Make sure that the motor spins freely and that there are no unusual sounds or vibrations. If you notice any issues with the motor or propeller, do not fly the aircraft until the problem is fixed. For EDF jets, you may not be able to reach the motor. Instead, blip the throttle and listening for any abnormal noises. Also listen for the motor revving up to speed and back down to speed in a normal kind of way. Any unwanted friction in the system will behave differently shortening the amount of time the rev up and down will take. 

5. Landing Gear Check

The landing gear is often overlooked during pre-flight inspections, but it is critical for safe takeoff and landing. Inspect the landing gear for any signs of damage or wear, and ensure that it is securely mounted. Verify that the wheels spin freely and that they are not bent or damaged. If you have retractable landing gear, make sure that it is working correctly by cycling the gear prior to the first flight for the day.

6. Wing and Fuselage Check

Inspect the wing and fuselage for any signs of damage, cracks, or wear. Ensure that the wing is securely mounted, and that there is no slop in the wing mount. Check the wing and fuselage joints for any signs of separation. If you notice any damage, do not fly the aircraft until the issue is fixed.

7. Center of Gravity Check

The center of gravity is crucial for the stability and control of your RC airplane. Verify that the center of gravity is within the manufacturer’s recommended range. To check the center of gravity, balance the aircraft on your finger at the designated point. If the aircraft is nose-heavy or tail-heavy, adjust the battery or weight distribution accordingly.

8. Range Check

Before taking off, perform a range check to ensure that your aircraft is receiving a strong signal from your radio transmitter. Walk a safe distance away from the aircraft while monitoring the radio signal strength according to the directions found in your operators manual. If the signal is weak or if you notice any interference, do not fly the aircraft until the problem is fixed. This is only most critical to test when you are making a first flight or something in your airplane has changed.

In conclusion, a pre-flight checklist is crucial for safe and enjoyable flying of your RC airplane. By following these essential items, you can prevent accidents, prolong the life of your aircraft, and improve your overall flying experience. Always perform a pre-flight check before flying, and do not take any shortcuts. By doing so, you can ensure that you have many successful flights to come.
