    i'm reading, (and trying to see how to tune up the PID loop) but i'm thinking, do you know a tool that you can use to tune and test the PID on the bench??

    and seens i'm reading the chapter "PID tuning software", i'm asking if there is a chance to see an auto PID tuning software in the fututres versions of the soft?

    this afternoon i'll fly it without GPS and try to change some values and see if it oscillate (but how can i see on bench cause that would be quicker)

    Jordi,
    I think that current sensor would be a great addition to your shop and the 2.2 code.

    You need a current sensor, you can use Bill current sensor found in sparkfun. And you still have ONE analog port (analog 4) in the ardushield that can be used to measure the amps you system is happily eating.

    I understand the voltage monitor. What I need is to monitor how many AMPS the motor and/or system is using.

    Earl, try this one:

    Hi Jordi,
    I got my speed sensor board today.
    Also, do you measure current on plane motor and which sensor ?
    I know how to do battery voltage with a resistive divider.

    Gerber,

    900mhz is the best choice.

    Hello friends,

    I would buy the equipment to mount my UAVs
    I have questions regarding the XBee modem, could you help me?
    I am using 72 MHz RC
    Transmitting video and audio of 2.4 Ghz.
    I buy the 2.4 GHz XBee or 900Mhz?

    Thank you,
    Gerber

    I can imagine how it fly's. And this part will happen to everybody that uses any autopilot. The PID gains much be adjusted. You need to have a strong knowledge of PID control loop (not so complicated). You can start having an idea reading this:

    i was flying with GPS ,

    i'll try without tomorrow and i'll try to make a video to show you how it flys!

    thank's for your quick answers Jordi!
