I am just starting out making a UAV with a Bixler 1400mm wingspan and I have a few questions about the servos. On the HobbyKing website, it says that four 9g servos are requred. I have opened the box and seen that there are already several servos mounted in the wings and fuselage. Does this mean that I would not need to get four more servos, or do I need to get four more servos?
Also, I am a little confused by which batteries I should get. I will be using an APM2 to control the plane, with several radios onboard, as well as an FPV setup.
Any help with these matters would be greatly appreciated. Thanks!
