They are very cool little cards, I'm impressed and have been having lots of fun loading sounds and playing with them. I haven't found out if they can play sound when a trigger is released though, that would be a nice feature. I like projects like this and tanks are a form of RC that doesn't have to do with my actual job, which happens to be for a manufacturer of RC components for ground vehicles. It's a nice break from the madness of the other part of RC my life revolves around.

That's good to know about the possible trigger issues, hopefully I can figure something out if I run into any problems getting them to work. If my amps would hurry up and get here I could start actually working on getting it all wired up! I'm betting is has something to do with the PWM signals since the motor drive circuits aren't full on until full throttle, and even then the HL MFU might not actually be letting them have full battery connection.
