| The design for the AR7100 was based on the JR 8717 servos that run on 8.0v. A two cell lipo for the RX pack powers the servos directly and the RX has a 6.0v step down converter.
The only thing I dont like about the set up is the voltage to the servos won't be cosistant, it varies from 8.4v to 6.4v, and for those of us who are anal retentive, a consitant voltage to the servos is a must.
The other thing is that you are stuck using a two cell pack, I have a bunch of 3S 2100mAh from my 450s, I get 8-9 flights with them on the nitros.
I know that more electronics leaves more room for incedent and the AR 7100 does simplify things.
The Castle BEC is very small, and about $25. You program it with the castle link from you PC or laptop, you can pick any voltage from 4.8v to 9.0v
