SPEDIX ES25 BLHeli S 25A Opto Esc D-SHOT compatible for Drone Racing UK

The Ultimate Budget ESC without comprimising on quality or features. 

Spedix ES25 speed controller is designed for 150-280 size racing multirotors. The product is powered by high performance EFM8BB21 MCU, and flashed with the latest BLHeli_S program. With the combination of dedicated drive chip, this speed controller has excellent response speed and efficiency. The filter circuit of ES25 is composed of 12 low ESR capacitors, a number much more than competitors that use only 4-5 of them. As a result, ES25 has less current ripples and higher system stability, and less interference to wireless video transmitters.

In additional to excellent design, ES25 is also made of top quality electronic parts. It is composed of 3 Oz gold plated PDB, and genuine components from estimated suppliers such as STMicroelectronics of Switzerland, TDK of Japan, and AVX of USA.

The Spedix uses the BusyBee2 MCU technically labeled EFM8BB21. This is the better of the two MCU’s. Hardware across BlHeli_S ESCs tends to be very similar, if not the same. Spedix is using some quality parts though including 3oz gold plated PDB. The 25A version boast 12 low ESR capacitors that suppress the current ripples. They even say that this provides less interference on the video system of a miniquad.

Excellent design, authentic electronic components, and good manufacturer process all together make the ESC an excellent product with great quality, reliability, and stability. Furthermore, the size of the product is managed to be as small as most compact products in the market.
