  Because Plane is clever.  A Plane can only be in one mode at any time.  Its a waste of RC channels to have a whole channel dedicated to a mode.  So, instead Plane supports FLTMODE_CH.  A single channel where you can set 6 different modes by configuring 2 switches correctly on your transmitter.  If you make both switches all the way down or up as RTL then that can be your "panic button".

  @ Aeropixel I agree I don't know why all options aren't available on 6,7 or 8 or even 9 for that matter. What could be the reason for this I have no idea...

  @Mark  you can find out about the beaglebone and the Pixhawk fire cape here.  It is now being sold and developed by Erle Robotics

  How i wish i can buy 1 from 3DR. I know that 3DR is a great company. But due to lack of Financial support I'm trying to find the cheap yet quality assured APM.

  Do you guys think this APM 2.6 clone is a good deal?

  What are the other things i need to buy in order to operate this? compass?

  Hello everyone,

  I'm a complete beginner with zero experience in building planes and in the process of learning (via youtube/and this forum). My first project is going to be a skywalker X5, all parts are ordered and in the house.
  
  My first question is with regard to setting up a Turnigy X9 transmitter & what to set/not to set under the FUNC options. There are a couple of dozens different items there and I have no clue what most of them were.
  
  What I'm looking for is some basic numbers/parameters  to be set to start with.
  Hope that makes sense. TIA for your help.

  You need to set the ARSPD_PIN parameter = 65 for it to work

  Great to know! I guess I forgot there's also I2C on the APM2.

  The I2C digital airspeed sensors do work with APM2.

  If you don't currently have an airspeed sensor, you have to turn that off in the optional hardware menu. You're seeing junk data because it's reading whatever noise is on the analog pin and interpreting whatever it sees.

  You can't calibrate something that's not there and dial it in. The board is just seeing a bunch of noise.

  The APM2.6 can't use the digital airspeed sensor. Just get an analog one and follow the Wiki/Manual and it'll tell you how to get it connected and set up. Then go to the airspeed tuning section of the manual and get that going as well.
