Title: Motor not work
Post by: PhuongHeli on May 18, 2016, 01:26:54 pm

I am a newbie.
I have set up a heli with CC3d. All of servos work fine but the motor does not.
I use Futaba T8FG, sbus, YGE 60A ESC
I have attached my uav file.
I need help!
Thanks.

Welcome to this forum, PhuongHeli. You are doing well to get servos moving.

This could be your motor problem. From your UAV:
 <field values="0.01,0.71,0.85,0.94,1" name="ThrottleCurve1"/>
            <field values="-1,0.41,0.7,0.88,1" name="ThrottleCurve2"/>

The first ThrottleCurve1 value should be zero like mine from a UAV:
<field name="ThrottleCurve1" values="0,0.25,0.5,0.75,1"/>
            <field name="ThrottleCurve2" values="-1,-0.5,0,0.5,1"/>
            <field name="MixerValueRoll" values="50"/>
            <field name="MixerValuePitch" values="50"/>
            <field name="MixerValueYaw" values="50"/>
            <field name="RollDifferential" values="0"/>
            <field name="FirstRollServo" values="0"/>
            <field name="Curve2Source" values="Collective"/>

           Fix your ThrottleCurve2, also.

Note: I didn't have throttle set low enough to arm on one of my helis. I used the TH switch to get the signal low enough to arm. If that is your problem then you can re-calibrate manually or change the throttle minimum in the GCS or your TX.

Use your TX to set your headspeed / throttle after you have LP set up.

Hope it helps.

Your Throttle curve looks strange, not sure is needed, revert to default ?

Try calibrating the Esc
Try lowering the output refresh rate to 50Hz for Esc (the bank4 - yellow color)

Remove the spin at neutral checkbox for now, is needed for Heli ?

To f5soh
I have corrected my throttle curve as what daveapplemotors wrote.
Could you tell me about calibrating ESC.
Thanks you so much.

A question for you, PhuongHeli,

When you are connected to the computer via USB and you arm the motor does a voice say "ARMED" ?
If not try another method (or always armed) to arm the ESC / motor to test this.

hope to help,
Dave

Also I am afraid that you could have damaged your ESC using 330 Hz input. Can you test your ESC / motor without using your CC3D board?

You can manually calibrate Esc, look here:

Hey Dave,

I just noticed in reading through this thread (sorry to go off-topic on this) that your screenshots for the Throttle and Pitch curves show a "Source" drop-down.  My LibrePilot (15.09) does not have that.  Is this something new in the next release? Or have I gotten something wrong here.  I have to go to System | Settings to change that on my setup.

Re dropdown screenshots

See Configuration / Vehicle / Curve Settings in the GCS.

 "always armed", this is the solution of my problem. I have set "always armed" and the motor work well.
Thanks every body so much, specially daveapplemotors.
