I love this ESC! Mine came with 4A SBEC and without a manual, but that's alright because I bought a program box with it, the one with the two LCDs. This is the first time I used a program box and it was a breeze to set things up. I set the START MODE to "very soft" and it's soft as advertised
This ESC is very good for helis. I was surprised to see how small it is. The Sbec is under the heat-shrink like it was a daughterboard, and it's still much smaller than my old 50A which is crap and it developed horrible jitters. Now I know what's a good ESC like and what's a soft start
When the ESC doesn't detect signal from the RX a tiny red LED will start blinking and there's beeping too. It's not very loud but someone might think you're on a heart monitor
The wire which goes to the RX has one of those watchamacallit coils; now you know that I'm not as tech savvy as Bruce but that's an understatement
So anyway I'm happy with this ESC and lowpricerc shipped it very fast.
