Are you sure that all the connections between your receiver and the naza are correct. Check the sliders in the software, move they the whreight way ? And have you check or you need to do a calibration of the naza module. You can see that if you check the gyro numbers, when they are offset you need to do a calibration.

1) Make sure your props are all in the right direction. Just because your bottom motors are upside down, the props should be right side up.

2) Make sure your controls are calibrated in the Naza Software.

3) Make sure your ESC’s are calibrated.

Besides that Naza’s hate prop wash, I found you need to “pop” them off the ground and get above the prop wash to acheive stable flight.

I have the 850 so don't know if this applies but I think your centre of gravity is way off.

I have my packs way back, as far as the y will go. Saying that my friend who has a 700 had this exact thing, on take off it went forward like that, he moved the batts to the back and it was fine

Thanks for reply. Can you tell me what is his gain setting or yours? Mine might be to high?
If it is not much would you be kind enough to look through my video part 3 incase I have missed something that I forgot to do?

Thanks
Mo

Im around the 130 mark and he is very high, around the 190's.

That doesn't look like a gain issue.

Either some props on the wrong way or the centre of gravity is way of. Move the pack right to the back and try again if you have not already.

Take off the props and do a motor check in assistant and see if they are responding correctly. If they are then you might have your props on or going the wrong way... or as someone else mentioned, your CG is way off...although from looking at your video(3) it doesn't look like its a CG issue.

One last thing, did you do a Radio set up, making sure that a of the trims, switches, sticks have been properly calibrated and that your trims are zero'd out? I'm talking about within the radio itself, not with Assistant, although you would do that next.

By the way according to naza software when i choose the craft type in my case x8 do i have to have motor nr. as described in naza or can I choose my own motor nr. As long as the 4 top motors are ccw and bottom are cw.

Thanks

You are saying that your trasmitter doesn't have any trim function? Does assistant have graphs that display when the motor is running so that you can check things like the are all spinning at equal RMPs?

Click to expand...

You have your motors setup incorrectly. Motors should be 1-4 on top of craft and 5-8 on bottom.

So front right arm should be motor 1 and 5. Not motor 1 and 2.
