Castle Creations Embraces New FAA Regulations

Drone outside building

Olathe KS, June 23, 2016 – Castle Creations, the leader in electronic drive solutions for unmanned aircraft systems, welcomes the new Federal Aviation Administration (FAA) regulation announced this week. The new rules will make it easier for American businesses, farmers, nonprofits and government agencies to use drones in their work.

Tuesday, the Department of Transportation’s Federal Aviation Administration finalized the first operation rules for routine commercial use of small unmanned aircraft systems (UAS or “drones”), opening pathways towards fully integrating drones into the nation’s airspace.

“These new regulations open up a world of exciting possibilities for not only Castle Creations, but our commercial customers as well. We are quite pleased that the FAA is forming a more accepting policy in the industry,” said Castle Creation’s President Jonathan Feldkamp.

The new rule (outlined here) will become effective in 60 days, replacing the current FAA scheme that requires commercial drone operators to spend months waiting for an FAA exemption and to employ a pilot with a manned aircraft license from the FAA. It offers safety regulations for unmanned aircraft drones weighing less than 55 pounds that are conducting non-hobbyist operations.

The tough regulations have been a thorn in the side of business owners for years and have made it difficult for them to take a deeper dive into the benefits of utilizing drones in the industry.

“The innovative work we will be able to provide for our customers is endless,” said Brian O’Donnell, Director of Sales and Marketing for Castle Creations. “Our customers in the agriculture, energy and rescue industries are very excited about these new rules and what it is going to do for their bottom line. Castle Creations is excited about this growing opportunity and pleased to be a part of it.”

According to industry estimates, the rule could generate more than $82 billion for the U.S. economy and create more than 100,000 new jobs over the next 10 years.

For Castle Creations’ customers, it couldn’t be better timing. This week Castle Creations has released a firmware update that gives our commercial customers some much needed features such as reverse thrust and improved failure recovery technology. This will be followed by a release for FPV racers and a new platform shortly thereafter. Castle Creations continues to invest in R&D that will lead the industry for years to come.

New Product Announcement – X-BUS Telemetry Link



In this day and age, we all know RC is not just one way communication anymore. Telemetry advancements are rapidly emerging and Castle has collaborated with the radio experts at Futaba® and Spektrum® to release two incredibly useful and easy to use Telemetry products. Air and Surface enthusiasts now have a means to receive and view telemetry data on compatible Spektrum® radios when using their favorite Castle ESC’s.*

The Castle Telemetry Links were developed based on communication protocol from Spektrum®.  They become a communication module between the Castle ESC and the radio receiver and/or telemetry module where they are attached. The Castle ESC is then easily programmed through Castle Link ™ to allow the bidirectional communication required to transmit data to the radios.

When setup and utilized properly, real-time data will aid in the overall enjoyment and safe operation of model airplanes, helicopters, and cars. Imagine the benefits of being notified by a configured vibration or sound alert when a defined threshold is exceeded, such as battery voltage, battery current or ESC temperature. Pilots can now react and avoid potentially costly repairs as well as gain insight into other parameters that can reduce the performance of an electric power system, such as excessive ripple voltage.

Let’s face it, a modeler’s time and energy should be devoted to enjoying their craft. Telemetry is a powerful addition to any RC enthusiast’s tool box and provides confidence to maximize model performance and gain the competitive edge.

AUX What?!?

Adjective: auxiliary – providing supplementary or additional help and support.

Okay, we all get that. But what does it have to do with my speed controller?

When the Castle Phoenix Edge line was introduced for heli and plane applications, we announced the addition of the user programmable auxiliary wire. Our car enthusiasts will now have a taste of the simplicity and convenience if this feature with the Mamba X Series Electronic Speed Controllers (ESC).

In short, the auxiliary wire is an extra white wire, that when connected to an open channel on your radio, allows users to take advantage of on-the-fly adjustments (using your transmitter) that would otherwise be modified or set using the Castle Link Programming Suite. The feature is enabled through the Castle Link Programming system and one mode may be selected at a time.

Let’s take a look at the available options, we are certain you’ll find a favorite or two.

Mamba X Series ESCs (Mamba Micro X and Monster X)

Max Throttle Adjustment
The ESC’s maximum power is scaled from 10% to 100% depending on the signal received on the AUX wire. Perfect for passing the controls to children, neighbors or your boss.

Max Reverse Adjustment Mamba X Series AUX wire
The ESC’s maximum reverse power is scaled from 10% to 100% depending on the signal received on the AUX wire.

Max Brake Adjustment
The ESC’s maximum braking power is scaled from 10% to 100% depending on the signal received on the AUX wire.

Drag Brake Adjustment
The ESC’s drag brake setting is scaled from 0% to full brake depending on the signal received on the AUX wire.

Reverse Enable/Disable (Only works in modes with reverse)
Reversing is disabled when the controller receives an AUX wire signal above 50% (>1.5ms). When the controller receives an AUX wire signal below 50% (<1.5ms) or if the AUX wire is disconnected, reverse capability is enabled.

Torque Control Adjustment
The ESC’s torque control setting is scaled from 0.1 to 5.0 depending on the signal received on the AUX wire. Torque control is disabled when the input exceeds 1.9ms. Great for finding the perfect torque control setting for your track and tires. (Motor test must be performed before using this setting.)

Datalog Erase Enable
When the vehicle is stopped, toggling the AUX signal for a few seconds will erase the datalog. The motor will emit a long beep to indicate the log was erased. This feature can be added to any of the other AUX wire modes by checking the Idle Datalog Erase box in Castle Link.

Castle Phoenix Edge Series

Gain Input (ESC must be in a governor mode)
Connect the AUX line to an open channel on your receiver and use this mode to adjust the governor gain in real time. 0% TX signal equals a gain of 1 (min) – 100% TX signal equals a gain of 50 (max).

Phoenix RX+AUX wireTech Tip: Once the gain has been tuned via the Tx its value can be displayed on the data logger. Permanently save that value in the Edge via Castle Link programming and use the Aux. wire for another feature!

Audible Beacon
Connect the AUX line to an open channel on your receiver and this mode will use the motor to emit an audible locator signal when the AUX line is above 50%. The beacon is only emitted if the motor is not running.

Connect the AUX wire to 3 axis gyros that support RPM sensors and the ESC will toggle the AUX line at every electrical commutation. Divide this number by your number of magnetic pole pairs for mechanical RPM.

Arm Lock Key – requires ARM LOCK HARNESS
When the ARM LOCK key is in the socket, the controller will be incapable of arming. Once removed, the ESC will arm when it receives the low throttle command on the traditional throttle line.

RX Arm Lock

The controller won’t arm or run when the auxiliary channel is below 50% throttle.

Tech Tip: Loss of Aux wire signal during use reverts selected mode to default status.

So there you have it, the quick and dirty on Castle AUX wire functionality. Its sheer purpose is to provide at-your-fingertips options and adjustments to give you great flexibility, versatility and most importantly, the competitive edge!


Tech Tip / Installation Notice for Talon 90 and Talon HV120

If you are the owner of a Castle Talon 90 or Talon HV120 ESC  then this Tech Tip / Installation Notice is for you.

We have received reports of a small number ESCs failing in the field. After reviewing the failed units and their setups, we believe that we have found the cause. On certain applications, we have discovered that plugging the motor’s timing wires directly into the ESC can lead to a failure.

This can be caused by two factors:

One, the motor’s timing wires are inflexible and usually less than 3 inches in length. This makes it difficult to plug the motor’s male bullets into the ESCs female connectors. This can lead to damaging/bending the male connector, which in turn results in a loose and poor connection. As a result, this loose connection can potentially disconnect during use which can cause an immediate and catastrophic failure of the ESC.

Talon HV120_wiring1

The second potential issue is due to vibrations. Because the motor’s timing wires are stiff they have no slack or relief. Due to the extreme nature of some setups, the vibrations and the motor’s movement from torque can stress the female bullet connectors installed on the board and lead to a failure.

Castle highly recommends using 2 – 3 inches of appropriately sized silicone wire. The silicone wire (like the battery wires on the ESC) is quite flexible and provides some strain relief to the bullet connectors.

Below are two images from Helifreak user, “rotary guy” and a Talon 90 installed in a Goblin 500 helicopter. Note the extra lengths of wire between the connections and how this provides some post-installation flexibility, reducing the amount of “wire pulling” during flight while still maintaining a neat and tidy installation.

Beta Testers Wanted!

Castle is seeking knowledgeable and experienced R/C enthusiasts to serve as “beta testers” for a wide range of “possible future products” that are being developed for both surface and air vehicles.

beta-testingBeta testing is an important part of the new product engineering and manufacturing processes because it involves “real-world testing” by “real-world R/C enthusiasts”.

Do YOU have what it takes?
Beta testing isn’t for everyone. Depending on the product, beta testing can take a great deal of time and commitment on your behalf. It also requires above-average communication skills and the ability to provide accurate test data and findings back to the product development team.


What’s in it for me?
If you are selected as one of our beta testers and meet all of the requirements of the program, you will be the first group of consumers to receive a production version of the component FREE of charge, along with our unadulterated appreciation and the personal satisfaction of knowing YOU helped bring another cool, industry-leading Castle product to market!


Ready to take the next step?
If you are interested in becoming a Castle Beta Tester, please review Castle Beta Testing Agreement. If you agree to these conditions, are willing and able to meet them, you’ll find a link to the online Beta Tester Application form at the bottom of the agreement.

The information you include in your Beta Tester Application will serve as a database for possible Beta Testers. Once we have a product approaching beta testing that aligns well with the vehicles and power supplies you listed, someone from the Beta Test Program will contact you to finalize your selection to the Beta Test Team.

**Please note: Filling out the Beta Tester Application doesn’t mean that you’re automatically “in” or that you’re going to be selected for a Beta Test. We certainly won’t know about your willingness to be “part of the team” unless you do tell us about your R/C experience and available vehicles!


New Castle Link version available: 3.57.12

There is a new firmware update available for ALL brushless aircraft Electronic Speed Controllers (ESCs), including the Phoenix, Phoenix HV, Phoenix ICE, Phoenix ICE HV, Phoenix Edge, Phoenix Edge HV, Talon, Talon HV, Multi-Rotor and Thunderbird. This latest update is V4.22

Castle_LinkThis latest release of Castle Link addressed the following issues:

  • Bug fix for firmware version 4.20. Some users experienced problems reengaging the throttle after the brake was turned on at zero throttle. This issue only occurred when the brake feature was utilized.
  • Adjusted software to improve performance under heavy load.
  • Talon 15, Talon 25 and Multi-Rotor 25 had their current limit setting removed due to inconsistent operation. The software has been adjusted to measure excessive current using other means.

This latest version gives all ESCs access to features that were added to firmware version 4.20.

Firmware version 4.20 for aircraft ESCs has been “broken arrowed”. This means that any ESC that is currently utilizing firmware 4.20 and is connected to the new version of Castle Link (3.57.12), the program will NOT allow you to change ESC settings and you MUST update the firmware to version 4.22.

We also made some edits to the text of the “connection status” boxes to make it easier for users to determine whether their status is connected or disconnected. This was done to help red/green color blind users determine the connection status of the Castle Link and ESC.

For more information, visit the Castle Link page from the Castle Creations website (click on the Downloads tab). And don’t forget, our Tech Support page has a number of documents and FAQs to help you with the tuning and setup of your Castle Creations ESCs.
