Advice on instability

[Charles Dillard]

Hi, all, I have a quadcopter with a very stable carbon fiber frame, Turnigy escs, motors, receiver, battery. The processor is Naze 32. All of this is out of the box and brand new. My Spektrum 7 receiver has all settings - aileron, pitch, yaw - centered. I get this:

I have balanced the props.

I'd like some opinions on why this is rolling without me applying roll. All I'm doing here is applying throttle. I would think it would go straight up.

This has been an on-going problem with my quads and I'd like to get other thoughts on this and especially how to troubleshoot. Many thanks for your replies.

Also, PID tuning is out of the box.

So this happens on multiple quads you have?

Was the Naze setup by you?

Are you balancing props? If your using CF props, they almost always come terribly unbalanced, and the vibrations throw the sensors off.

 

[GJH105775]

Props are the most likely cause, but if the quad itself is not balanced then that will hurt it also.

Hi mate what setting is the spektrum on, it needs to be aero no mixing on any part of it , to start off all trims and sub trims need to be zero, then when you set up the Nase you use sub trim to trim the naza,then the quad need to set on a level surface (100%) level then calibrate sensors , sorry if you have done this but we need to start at the beginning

Hi answers to questions

Jackson: Naze 32 set up was by me,but it's out of the box; I made no changes to PID or other settings.

GJH105775: I balanced the props. The copter is balanced.

Hotneil: Calibrations done on level surface. Mixing all zeroed.

Everyone thanks for your input. I will double check your suggestions and let you know.

PID tuning will need to be done then (probably), and are you calibrating the sensors on a level surface?

 

[Charles Dillard]

Calibration was on level surface. Since the copter is rolling 10 degrees, the suggestion to look at prop balance would be the first way to go on this. Remember, this is a $30 processor so that alone is suspicious. Say all the bad things you want about DJI Naza boards, they fly well. You pay more and you get more.

Have you setup the correct channel mapping to match your DX7 ? Are you using Cleanflight?

 

[Charles Dillard]

Good question. Yes the channels are correct, for instance if I pitch the transmitter, I'll feel the back end push up. As for Cleanflight, I used Baselight Configurator most current image, should be ok so long as its not beta. I'll check 2 b sure.

 

[Jackson]

Well I know you are unhappy. Why don't you start over, this time with Cleanflight, a newer enhanced fork of Baseflight. You'll be reflashing your Naze and starting with a clean slate.

I like Painless360. Here's a little tidbit for your TX.

And here's his Naze/Cleanflight guide. Complete playlist.

So easy to miss something basic, but maybe you just got a bad Naze32.

 

[Charles Dillard]

Better luck today. Re-flashed board, re-calibrated accels, (this is in Baseflight), lots of balancing on the props, reversed aileron. Did not touch PIDs. Took it to nearby field and it did a lot better. Still rolls slightly, but it flew in a moderately controlled fashion. (No video yet) Thanks for comments on this page, you got me thinking!
