Q Brain ESC Learning Experience

[STFDAC20]

Building my Quadlugs 540mm kit, using Naza M-Lite, Q Brain ESC and some Turnigy motors I had quite the head scratch'r going on. Every time I spooled up, the quad would get to 50% throttle and just flip over. No lift, just a nice solid flip.

After double checking my blades, and motor spin I was good. Maybe I still had the wrong blades - they broke so I had to replace them. Checked again. Went out in our Michigan weather (extremely cold) and boom it did it again.

After a couple Google searches, all relating back to connections, are your motors connected to the appropriate spot in the flight controller. I double checked all my wiring - EXCEPT the Q Brain's leads to the motors themselves. It jumped out at me instantly!

I mounted the Q Brain ESC with the power leads to the rear of the quad. I was so wrapped up in running wires cleanly, I neglected to notice I turned where M1 was going. My motors were not corrected to the appropriate supply on the ESC. BINGO! Simple. I missed it completely!

I think it goes without saying, but always check your work thoroughly. I am going to give myself the check, wait at least another 15 minutes and check it over again - from here on out!

Be safe out there!

On a side note - only props were damaged in this learning experience. Nobody was hurt - but I had a couple blades fly near me.

Hi there

I am having trouble to connect my qbrain with the naza lite. Do you mind if i ask how you connected the cables from the esc to the naza? Did you cut the red cable on the white or kept it? Which order did you used?

Now i am trying to use RoWB or WORB layout but i hear nothing else other than random beeps from the motors

I removed the red wire.



Make sure you use the throttle hub and calibrate!

 

[Flayzeraynx]

So you calibrated first then removed the red cable or before?

 

[STFDAC20]

I removed the red wire and then calibrated.

One more question. Have you connected the white cable to the rx directly and calibrated or rx to naza & esc to naza on m3 with white cable orientation you used?

 

[STFDAC20]

I believe I did the later since the Naza system gave the power to the Rx.
