Still no lift off

[lef149]

I started gathering parts to build a multirotor awhile ago I got a bunch of cheap parts hoping to get it to fly. Originally I was going to program an arduino to be the controller but changed my mind in hopes to get it to fly and switched to a naze32 rev5. Problem is it won't lift off, it keeps tipping to one side. I had to replace a motor because it would stutter at startup. But still no flight I'm using 1000kv motors and blheli esc. The frame I 3d printed and everything I try to lift off it always tilts to one side. Any advice or suggestions that may help please let me know.

Flipping out on takeoff is usually caused by either wrong motor direction and/or incorrect prop installation.

Or motors wired to the wrong outputs on the baord

Pictures of your build may help us troubleshoot too. We can see things like prop rotation direction for example.

I will try to get pics up soon. The motors are definitely going the correct direction and connected correctly. I checked each motor on cleanflight starting each one and verifinying direction.

Quick questions. Can the frame, because it was 3d printed and not perfect, cause some issues with flight causing this behavior? One thing I forgot to mention one of the motors, when on, causes it to tip down on just that motor. The other three motors will start to rise but that one won't. Another question, can a problem with the esc cause this behavior? I'm just wondering before I get a new frame or replace the esc.

The frame can cause weird behavior once in the air but has nothing to do with motors spinning or flipping over unless something like a broken arm has happened.

If one motor is pushing down instead of lifting it is one of two things. Either it is spinning backwards or you have the wrong propeller on that side. As far as motors spinning faster then others that sounds like a calibration issue.

Go to any of the quad copter build videos and follow the set up procedures as far as checking motor directions, prop placement and esc calibration specifically. If you check those things out and you still have problems post us a picture of your craft. better yet a short video of how it is acting. Then maybe screen shots of your gui screens so we can look for issues there.

I won't have time until this weekend but I will try to see if I can make time. If I can't make time I'll post this weekend. I'm new to all this sow what is the best place/way to post videos and photos?

 

[ElectriSean]

Photo's can be attached to your forum post, videos are usually posted to youtube and linked here.

This is the multirotor trying to fly

This is my settings, for some reason my mic wont work for me and i am

One thought...the FC is installed facing the correct direction right? If you have it rotated and forget to adjust in your settings it can do that.

 

[PsyBorg]

To me all the motors do not sound the same nor did they start at the same time according to my eyes and slowed playback. Did you by chance over look or maybe not do a motor calibration properly? That is an easy goof for people of all levels of building and setup.

Calibration

The first thing I would do is to recalibrate the escs and recalibrate the gyro on the nase32.

 

[lef149]

I've tried to calibrate them a couple times and still same results. Now the motors aren't all from the same supplier. Could that possible be the problem?

The FC is able to correct for differences in motors, ESC's and even props.

Have you checked this?

 

[lef149]

I'll double check but I'm pretty sure it's facing the correct way. I have blheli esc, to calibrate you set full throttle, turn everything on, once the beeping stops go no throttle, then after the beeping stops it's done, correct?

 

[lef149]

Thinking about it the fc is in the correct direction I remember checking that in cleanflight.

Yes, but you do this in the motors tab using the master slider so they are all done at once

 

[lef149]

Yea that's where I did them.

I followed the video on YouTube video that shows you how to set up a name 32 board done by flight test. Now why would one motor not start at the same time as the others if the calibration procedure is don't correctly?
