now I'm still working to find the correct PID parameters

 for a stable and no wobbling flight i have to set the P parameter unter 1

than i have not enough sensitivity on my RC

 

maybe someone has experience with such a small Kopter with relatively large engines!

 

or someone could rewrite the code for me ?

 

Thanks

Peter

    IT looks like Turnigy has other motors that come with the mounts but you cant buy the accessory pack that has this three screw mount?

    Peter where did you find those rotor end prop mounts for the NTM Prop Drive Series 28-30A?

    Hi Chad,

     

    a friend has made ​​the bubble

    I love the finished look of your copters, great job.  Did you make the bubble for the tricopter yourself?

    Thank you

     

    Unfortunately it is not possible to load the code with Arduino!

     

    which lines I have to change, so I can load the code without error?

     

    I'm still  play with the P-Rate and P parameters

    Did you try to increase thi P-rate term?

    If you increase that you can also increase a little the P-Stabilize to have more control.

    On my Quad, 50 cm. with KEDA motors, to have a good stability I had to increase the P-rate to 0.15 and P-Stabilize to 3.2. With default 0.12 I had to lower the P to 2.8 and still having wobbles and descent instability.

     

    But if you already tried that, to have more control on stcks you have to modify the code and compile it with Arduino. Of course at your own risk (even though that little bumble bee will not harm much :P ).

    The code to change is in radio.pde

    g.rc_1.set_angle(4500);

     g.rc_2.set_angle(4500);

    sets the maximum angle the copter will lean for Roll and Pitch respectively. If you increase this value the stick will be more sensible.because the range will be higher. In my set up I am using 6000 (that is 60°) as a value because I like a little more sensitive stcks...

    Hope this helps.

     

    Emile
