Spedix 30a 3-6s BLHeli-S. Did you read that closely!?…3-6S!! These ESC’s are the best! I personally love external ESC’s like these because if one does have any problems, you simply swap 1 out instead of the whole AIO (All In One) or 4-in-1 ESC. For the price, these ESC’s will handle nearly every situation with ease. Buy them, put them on your favorite build, and watch how smooth your flying becomes! Punch the throttle with confidence!


Spedix ES30-HV is the smallest and lightest 6S 30A speed controller in the category so far. It is designed for 150-300 size racing multirotors that have strict demand on power, size, and weight. This ESC use 6 standard MOS-FET with a low resistance of only 1.1mΩ. Compared to the common small size MOS-FET this standard component is much tolerant to current load and surge, and better heat dissipation. However, with our genius engineer design, the overall size of the ESC is almost the same as counterpart product using micro MOS-FET. With the hard work of our engineers, the size and weight of the ESC in controlled under 14.8x29x5mm and 7.9 grams, to be the smallest and lightest in the category in the market to date, without any sacrifice in power or reliability. 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 ES30-HV is composed of 12 low ESR capacitors, a number much more than competitors that use only 4-5 of them. As a result, ES30-HV has less current ripples and higher system stability, and less interference to wireless video transmitters. In additional to excellent design, ES30-HV 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. Excellent design, authentic electronic components, and good manufacturer process all together make the ESC an excellent product with great quality, reliability, and stability.
