Yes, you are right, it's a dual H-bridge.
The code I wrote using Bill Porter library, found in
http://www.billporter.info and with a lot of help from this forum.
The code is exactly that was in Arduino. The comments are in Portuguese, any help you can use google translate.
It is not the final version

[quote="a_shorething"]@tcholas, technically that's not an ESC, it's a dual H-bridge isn't it?
It's the same one I'm planning to use.
I checked out your youtube vid and it looks good. Is the Arduino code posted anywhere for that? Any chance I could get a copy of it?
