E-flite’s 30-Amp Pro SB brushless ESC offers up to 30 amps of continuous current with proper airflow and a peak of 35A. It drives up to 5 analog or 4 digital sub-micro servos with the BEC on any recommended input voltage. This brushless ESC includes programmable motor braking, soft start for helis and planes, timing, throttle input range and low-voltage cutoff. It also features auto motor shutdown in case of lost signal or interference. The safe power-arm mode prevents accidental starts.

E-flite 30-Amp Pro SB Brushless ESC
Works perfectly in my Blade 400 heli. I replaced all my servos with higher end versions and got this just to give me a little more juice. It handles everything with ease and doesn't even begin to get hot. Programming is easy even without a PC.

E-flite 30-Amp Pro SB Brushless ESC
ESC's seem way overpriced these days. I have two of these, came with a parkzone T28 trojan and a F27 Stryker. They have a switch mode BEC which means plenty of power for 4 or 5 servos. Compare this to the Scorpion 30A ESC with switch mode BEC. The scorpion is $100 and this E-flite is $45.
