Stabilize mode toggle without a RC

Is it possible to toggle from manual mode to stabilize mode without the usage of a RC?
I am thinking of using Microsoft Visual studio to do the job. Modifying the program so that example F1 is pressed, the plane will toggle from manual mode to stabil

Help on 2_7 program!

Hi all.. I have been trying out the new program and i found a few questions to ask.

  • First, for the debug of sensors input, what does it mean by airpressure_raw? does it mean by pitot pressure? I always receive a value of 400+, never exceed 500.
  • For th

Stuck!

Hi all!
May I know what is the best way to test the XYZ sensors?
The values does seem to be very stable.

Just to confirm, the XY sensors are suppose to be in charge of the yaw and roll?
And Z sensor is in charge of the pitch?
And how do we read the value

GPS program

Hi guys, can anyone tell me which GPS program is giving out an accurate data?
The data that I meant is Latitude, Longitude at least.

From the EM406 gps tester that I've downloaded, the data does not seem to be clear.
Does gs means ground speed? And wha
