The Spedix ES30-HV is the smallest and lightest 6S 30A speed controller in this category so far. It is designed for 150-300 size racing multi rotors that have a high demand on power, size, and weight. This ESC uses 6 standard MOS-FETS with a very low resistance of only 1.1mΩ. Compared to common small size MOS-FETS this standard size component is more tolerant to current load and surge, and offers better heat dissipation. However, with our excellent engineering design, the overall size of the ESC is almost the same as counterpart products using micro MOS-FETS. With the hard work of our engineers, the size and weight of the ESC is now under 14.8x29x5mm and 7.9 grams, to be the smallest and lightest in this category, without any sacrifice in power or reliability.

The product is powered by a high performance EFM8BB21 MCU, and flashed with the latest BLHeli_S program. With the combination of a dedicated drive chip, this speed controller has excellent response, speed and efficiency. The filter circuit of the Spedix ES30-HV is composed of 12 low ESR capacitors, a much greater number than competitors that use only 4-5 of them. As a result, the ES30-HV has less current ripples and higher system stability, and less interference to wireless video transmitters.

In addition to its excellent design, the ES30-HV is also made of top quality electronic components. It is composed of a gold plated PDB, and genuine components from estimated suppliers such as ST Microelectronics of Switzerland, TDK of Japan, and AVX of USA.

Excellent design, authentic electronic components, and good manufacturing process all together make this Spedix ESC an excellent product with great quality, reliability, stability and performance.
