  Logan, thank you for your help. However, the hook-up you suggested is what I have on my set-up, so I guess that's not my issue. What's odd is that the board did power up initially and I went through the initial RC set-up with calibrating the sticks; got the ESCs calibrated; all motors & servo worked, although the servo  seemed connected to the throttle inputs. Also, I could not arm or disarm the copter - copter only responded to ESC calibration process. I also started to notice  that when powering up  the copter the board LEDs don't seem to work to show initialization is complete. So I don't think the board is powering up with connection to copter only (Tx/Rx/Battery & no usb). Board powers and connects to computer fine w/ USB only, as when installing firmware.

  @Dan Skaggs

  Assuming you are using the AR8000 receiver the hookup should be as follows.

  Aile to Input 1

  Elev to Input 2

  Thr to Input 3

  Rudd to Input 4

  Aux 1 to Input 5

  You will probably want to reverse Aileron, Elevator, and Rudder from the RC controller.

  I just bought my APM 2.5 from DIYdrones to hook it up to my simple tricopter. Can anyone help with a wiring diagram to connect my spectrum receiver properly to the board? I'm using the power module to power the APM board. I've loaded the firm ware to the APM, hooked up the motors and servo per the wiki instructions, calibrated the escs, but can't get the motors to arm. Also, after calibrating, the throttle seems to move te servo for yaw as well as increase throttle, yet the yaw, roll & pitch stick movements have no effect. Any help is appreciated.

  @Rob, any pics would be useful.

  Thanks.

  @Bobarry

  The holes are so you can stick a rod through the hub and really crank it down tight.  I use a really small hex key and it works great.  I had props flying off until I figured that  one out :)

  @Bo
  I suggest posting to a forum, you will receive more help.
  The hubs have to be on tight. I check and double check but they work. I have never had one come off.
  Also I agree with Jeff. Quads have the potential for serious injury. I took baby steps when I started learning and I'm still learning.
  Check your setup again. You'll get in the air, safely.

  Some of these posts make me very nervous that some people are putting powerful Quads/Hexs in the air with little or no flying skills/experience. I have been using the APM boards for a while now and also fly 3D helis daily. Just my opinion. You should at least master a simulator program before ever flying anything unless you are in the middle of a large field and are prepared to crash . Please realize that an injury from a "Drone" gets public attention and can put a strain on the hobby. Commercial pilots learn to fly countless hours before they engage the autopilot on an aircraft. I do not mean to be out of line but this would be considered by many as basic common sense. Be safe

  Help! I put blades on my Turnigy motors, tightened down the cute hubs, revved up to see what happens & one of the hubs flew off!

  What can I do?

  The hubs have 2 holes on them but it is clear thru them, so set screws aren't in order.

  Fortunately I still have setup problems, because full throttle didn't get me off the floor.

  Any help appreciated

  Thanks Randy, I'm new to this and didnt know about that forum. I think it was a casual comment, not in that area. Lots of reading going on and my Arduflyer is almost ready for something (hopefully takeoff). I have 0 experience in RC, just a computer nut having fun.

  Did you look at the buy, sell trade forum?
