Problem still with motors spinning up by themselves!

500 frame
1000kv motors
30amp esc's
5.2a battery

Title says it all really.

Ill thottle my radio just enough to get the motors to start spinning, ill let it sit there for like 30 seconds and all of a sudden they will start to spin up by themselves.

I redid the whole cc3d board, reprogrammed and calibrated. It was perfectly level and all.

Yea pretty much bout to give up on this

Any fix?
 
is it trying to take off ? and increasing power to do so ?

.. if I do the same on my hex or quad the power slightly increases after time.. if I lower the throttle to the bottom they stop spinning OR this can be changed in parameters in flight controller to spin when armed...
.. this means when throttle is low they just spin,, if I raise throttle a little the props start to spin up..

when flying does the drone act this way,, or is it stable once the sensors are airbourne.. ?
 
It almost takes off yes but only on 2 motors. not all the motors will spin up like this. Only 2 of them.
I throttle my TX just enough to get the motors to spin. I do not touch the throttle again and all of a sudden 2 motors will just start to spin up very fast until it almost takes off. I can link a video I have on youtube of this.

Once I take off (which is very hard because of this motor issue) it seems to fly just fine. And before you ask, yes I take off and test on level surfaces. I use an actual level to make sure everything is 100% level lol.

Jackson: I've let it sit there like that to do testing and programming on the drone. But recently now its almost instantaneously.

My first thoughts are... sitting there with what look like carbon fibre props on a quad with - seeming unwanted throttle increase.... is not wise.
I have spent months sorting issues like this and the one thing I found was that using LP and going through the setup - the bit where you set the ESC - did not do well for me - I found the answer was to emulate the Cleanflight method. No Battery, link all your motors - take them up to full - plug a battery in and immediately drag the motors to zero.
You do not identify the type and make of ESC. Are they 125 one shot, SimonK, Bheli etc,.
I found all my problems lessened when I sorted the ESCs out!
Look at this LP ESC calibration.

Im not following about the carbon fiber props.....What about them are you asking?
Im not sure what the cleanflight method is to be honest. I mean in LP I used there setup wizard and calibrated the ESC's.

The ESC's that I have ae 20a F-20a fire red series Simonk RapidESC from RTFQ

That's normal behavior, when it's just sitting there.

 
I mentioned the props -only from a safety aspect - plastic or carbon fibre - they can still cause serious injury to you.
Better to stick some masking tape if you need to see direction - other than that - your concerns appears to be about motors spinning - so you do not need props - or you may need the luck of the Irish - to avoid injury.

Update: had a browser crash ..

This is a link to an LP tutorial on ESC calibration - it basically emulates the Cleanflight method.

Have you still got the "Live testing" tick box - ticked - in the motors section? If so... then its likely the cause of your problem.
