Hey Rod they are killer looking birds!
Did you go soley with a Life battery for your servos or a battery and BEC?
I've been agonising over what I do with my Gaui X5. It's got a decent built in BEC but I've bought a Western Robotics BEC but I'm still pondering using an external battery as well as the WR BEC if the weight isn't too bad. Last thing I want is a $300 repair bill if I have brown out.
How did the Synergy go as well?
Since you posted about it and I watched that vid, I'm thinking if I get a 700, it might just be an E6/7!
