Motors lacking power - Questions

I have a 330 with Naza/GPS. It was flying fine and then fell out of the sky. I put it back together with the same configuration. Now it flies, but barely. It is like there is not enough throttle. It barely hovers. As I said it is the same config. Note... I am using the ipeaka/Simon and I power motors. After my crash I realized I had failed to pull the red wire from the ESC. Wondering if this could have messed something up. Remember it flies correctly, but has very little power. I double checked my TX calibration and my TX is setup the same. I even threw the battery on my 450 to insure that it was not the prob. If I don't come up with something here then I will try swapping the Naza controller.

Thanks!

Take all the props off, start the thing up in manual and see if the motors shake, if one makes more noise than others, feel the base for vibes, etc. good start.

i have no idea what leaving esc bec's on does.......

Thanks. I will check it out.

Triple check all your connections - after a crash you could have a faulty connection somewhere.

Welcome to MultiRotorForums.com!!
sometimes when heli's seem to not have any power it's because the altitude hold is on at take-off. so while you're trying to climb, it's trying to keep you at or close to ground level. look in the NAZA Assistant and make sure that the altitude hold isn't enabled or is incorrectly set up.

I may be misinterpreting the NAZA's altitude hold but thought I'd mention it anyway.

mis interpreted it..... it doesn't hold an altitude, it is dynamicaly holding it with the throttle. up throttle is a controlled increase in altitude, mid stick holds it like your thinking, lower the stick it falls at controlled rates.......gps atti and atti mode

manual is just like HFP manual

You might want to provide more complete information to enable a more comprehensive answer, e.g., lift off weight? firmware version(s), stock or alternate escs @ 30A or ? etc.

It is doing it in all modes. No hover till about 3/4 throttle.

I did not really think that was relevant when it did fly fine and I just stripped it down to change broken arms and verify the solder points.

The copter is not with me but let’s see if I can remember :)
Naza M with latest software according to assistant, Naza GPS, ipower motors 2217, ipeaka 30amp ESC preflashed with simonk (version unknown), 2200 mah battery, 8x4.7 gemfan props, AR8000 RX. Sorry I don't know the total weight at the moment. Nothing else on it, but LEDs and a turnigy switch for the LEDs.

Thanks

Welcome to MultiRotorForums.com!!
i would try recalibrating the ESC's individually using the transmitter, also recalibrate the flight controls using the Assistant. Make sure the throttle trim is all the way back when you do each calibration.

1st just remove the Turnigy switch and try it again. Personally I doubt there is any internal damage to the NAZA electronic components.

Total weight with battery is 907 grams. It is like it flies correctly, but I can't get it enough throttle. To me the ESC calibration should be correct. It would be odd that all 4 would be off the same amount. Please correct me if I am wrong.

I do have one motor that seems to be vibrating more. How does this effect the entire system? I would really appreciate some insight. I will try swapping that motor out.

Disconnect a motor. Connect all 3 leads together and try to spin the motor. If the spin is further impeded when the 3 leads are connected together, your motor windings should be fine (magnetic drag). Also you can connect a multimeter and check continuity to the case. If not continuity, there is no winding short to ground which is good. You can also connect the motor and esc directly to your receiver output and calibrate joystick range directly from your Transmitter, bypassing the NAZA entirely. Results will provide further insight as to root cause.

FIXED: I failed to remember that I was using a different RX even though it was the same model. I recalibrated the esc's and all is good. Opinions/facts... Was it the RX possibly as the signal may be somewhat different (range)?

Thanks for all the help from everyone!
