VoltaraRC ESCs: The New Contenders in the FPV ESC Arena!

Alex -

Ian, from MadsRC explores the realm of VoltaraRCs Electronic Speed Controllers (ESCs) created for compatibility with both KISS Ultra and Betaflight systems, in depth reviews everything you need to understand about the fresh 70 amp and 50 amp ESC models; encompassing their attributes efficacy and overall usability.

Overview of the Voltara ESCs

Liviu designed the Voltara ESC units to cater to the FPV industrys needs following the discontinuation of BLHeli_32 products.They offer an, in house design that encompasses both hardware and software features for functionality and performance enhancements, in the market.

The review discusses two models. The 70 A full size version and the 50 A mini version ESCs, with a focus to integrate smoothly with KISS Ultra and also being adaptable, to Betaflight according to Ians emphasis that these ESCs come pre configured for use guaranteeing an user friendly setup regardless of the flight stack applied.

Unboxing and Specifications

When you open the 70 amp ESC package for the time you will discover the ESC enclosed in a static bag along, with a wiring harness and a capacitor rated at 35 volts and 1000 microfarads (µf). The harness is designed to fit KISS Ultra flight controllers. Can also be adapted for use with systems, with minor modifications.

Specifications of the 70A ESC

  • Rated Current: 70A (capable of 80A)
  • Voltage Input: 3-8S
  • Size: 40 x 39mm (42.8mm with wings)
  • Mounting Pattern: M3 30.5 x 30.5mm
  • Supported Protocols: DShot 150, 300, 600, 1200, 2400 (recommended DShot 2400)

The ESC is designed with a nano coating that makes it more durable and resistant to moisture damage.The board includes sensing shunt resistors for each motor output which enhances its performance and safety by enabling the ESC to quickly identify and address any problems as they occur.

Configuration Options

When used together with a KISS Ultra flight controller the 70 amp ESC provides setup choices.

  • Current and temperature limits
  • Ramp-up power settings
  • Slow start and spin-up settings
  • Rotation direction adjustments
  • Beeper volume and beacon time settings

The Voltara Mini ESC

Ian then presents the Voltara Mini—a 50 amp ESC crafted with a 20, by 20 millimeter mounting layout that is more condensed, in size yet packed with functionalities found in its bigger counterpart.

Specifications of the 50A Mini ESC

  • Max Current: 60A (50A continuous)
  • Dimensions: 37 x 33mm (37 x 37mm with wings)
  • Weight: 12 grams

Similar, to its version the Mini ESC comes with a water repelling coating. Is compatible with DShot protocols. Its tailored for the KISS Ultra Mini setup perfect, for constructing light and agile drones.

Firmware and Features

The Voltara ESC stands out for its custom firmware created internally and operating on STM32 microcontrollers which enables monitoring of motor outputs to prevent problems such, as motor shorts effectively in comparison to the usual ESC models that shut down completely under similar circumstances due, to its individual current sensing shunt resistors that can detect which motor is consuming too much power.

Configuration and User Experience

The Voltara ESC can function away without any adjustments needed; however KISS Ultra users have the option to utilize the KISS UI or OSD to refine settings as needed for a customized setup experience tailored to preferences.

Performance Insights

Ian talks about his time using the 70 amp ESC. Mentions that it functions as effectively, as other ESC units hes used before. He points out that he tested it with both KISS Ultra and Betaflight setups and found no issues with its performance or features. The ESC offers a combination of reliability and efficiency that makes it a suitable alternative, to BLHeli_32.

Final Thoughts

In terms Ian believes that the Voltara ESC models offer a choice, for FPVers seeking dependable and effective performance. Their distinct characteristics and ability to work with flight setups make them a strong option, in a sector that was previously controlled by BLHeli _32.

FAQ

Can the Voltara ESCs be used with flight controllers other than KISS Ultra?

Certainly! The Voltara ESC units work well with any flight controller that's DShot compatible, like Betaflight.

What are the key advantages of using the Voltara ESCs?

The main benefits comprise personalized monitoring, for safety measures specially crafted software designed for optimal functionality and an easy to use setup procedure, via KISS Ultra.

Where can I purchase the Voltara ESCs?

You can find Voltara ESC units, at the KISS Ultra store as other retailers such, as TBS and Pyrodrone or Unmanned Tech company.

Are there any major differences between the 70A and 50A ESCs in terms of performance?

Although the 70 amp ESC can handle load, than the other ESC options available in the market today, with similar features and performance capabilities; deciding between them primarily hinges on the unique needs of your project.
