Hi,

I'm new at APM as autopilot for planes, I have other fc like hoverfly and YS-X6, but this is the first time I'm building a plane with an autopilot.

I just bench built my APM 2.5 + RFD900 Telemetry and my servos can't move at all. I did read a lot to find out whats happening but couldn't find an answer. Some considerations.

1) My build is a X8 wing

2) I'm powering APM via input trought the radio using a Castle Creations BEC (on the RX) 5.2V

3) I can connect via telemetry and all the sensors are working fine

4) I get a 3D Fix from GPS and I get a fixed Yellow (B light) and a fixed Blue light (GPS FIX)

5) I did the radio calibration and all the channels I connected are working fine via TX/RX and the numbers are the expected in MP. 

6) I did connect my new servos directly to my receiver to test them (Hitec HS-645MG) and they're both working.

7) Checked 3 times every connection and everything is ok

8) I didn't not connect my ESC yet, but I think its irrelevant, the servos have to work without it. (does it?) 

What I'm doing wrong? Whats missing?
