Glacier, thanks for the input! I bought 4 of the nippy black 1608/160 motors and will test one today on my thrust stand with amp meter etc. to find out it's capability with different props. Awesome to hear that the 1.5A BEC will run 6 servos without issue. I picked up these outrunners from Hobby Lobby for $20 ea and the 30A esc are Tower Pro from Raidentech for $22.95 - their 10% sale. Likely the same you have. Looking back I could have probably gotten the Tower Pro 15/25A escs for $12.95.
What kind of amp draw and thrust are you getting from your set up?
All up weight?
Really want to get this right.

Would like to know of a 4 motor bomber that isn't too big so I could convert with some of these smallish inexpensive outrunners.
