Are you using V1.8 or V1.8 Patch 1? V1.8 had auto level issue that V1.8 Patch 1 fixed. If V1.8 didn't fix your problem just go back to V1.7. V1.7 is not a bad firmware. It just doesn't have all the features to deal with the ITG3200 gyros.

Please do not get confused.This is a modification to the code and not a patch.Originally posted by me,and responded to by Alexinparis ,by modifying the code on line 463 in the Multiwii1.8 tab by removing the 2* this will reduce the control authority in autolevel mode.
This will not fix the drifting problem from FF flight unfortunatley

How come if i can fly fine in acro mode and while in the air i switch to stable it leans alot to the left? But if i start with stable mode it stays level... Have basicly no trim on the tx.

The complaint on the 1.8 drift seems to come from flight in Acro mode and then switching over to level mode. If you're staying in level mode then you may not notice any issues.

[QUOTE=SeismicCWave;19207237Go to Home Depot and get some towel rack replacement square tubes. They are shiny aluminum and light weight.[/QUOTE]

I did this with the arms for a flat hex I'm working on. Those tubs will deform if you over tighten them. I ended up putting trimming down and fitting in some sq wood 'plugs' in the outer arm ends to help secure the motors as my motors have the mounts screwed into the tubing and they wouldn't stay flat with each other. I'm thinking of moving over to a 'pinch' mount for the motors. Either way, the wood plug on the arm ends should prevent the tubes from deforming.

I also used some Home Depot towel rack tubes, they do work but as Vantasstic said they will deform because they have a very thin wall thickness. I even had some of them bend a little just from drilling the holes in them. I ended up abandoning them because of this, though I didn't try putting any supports inside of them.

The towel rack tubes are only 1/32" thick, if you look online you can find square tubes that are 1/16" thickness which are still very lightweight but will hold up much better. I don't remember if Home Depot had square tubes 1/16" thick in the hardware section, my local Home Depot is on the smaller side and doesn't carry as much as some others do.

We have a larger Home Depot and they didn't have anything in the hardware side that would work other than some U-tube. My Hex arms are short so I'll try the towel rack arms first. If they bend up then I'll try either wood or go with thicker wall aluminum tubes.

not entirely true.

if you stay in auto mode without ever switching to acro, the quad will again lose level and bank one way or the other.

Could you tell when it does happen.
Only Hovering .. ?

if hovering only it is fine, but as soon as you reposition the quad a few times it loses level. Its never the same way either. one time it will be banking right, others times it will bank left, forward or back.

One thing is for sure. v1.8 is solid in gyro mode for slow forward flight and hovering. But 1.7 was too for me.
