The IS30A from Spedix is a new addition to one of the best ranges of ESCs on the market for racing and freestyle quadcopters. The IS30 has been designed for racing quadcopters running on 2-4s and does away with HV support but adds six standard-sized MOSFETs for improved reliability, better heat dissipation and lower resistance.
The IS30 has solder pads for connecting to your motor and arrives with a piece of semi-transparent heatshrink for you to cover the ESC when you are done soldering.
To avoid potential damage caused by mechanical stress, please install your ESCs with the aluminum plate facing the arms of your quad. If using zip ties, please attach a soft pad between ESCs and the frame of quad to reduce stress.
