RE: What servos with an Ultra Stick 40?
I run an assortment of Hitec standard servos in mine at 6volts. I had another one that had a bunch of Cirrus and Futaba clones in it and it flew just fine on 4.8 volts. I really love the Ultrastick. I enjoy my 40 so much I bought a mini so I can fly it in the park across the street.
