I have built an x quad copter, I have adjusted the multiwii code to reflect that, I have properly adjusted my ESC’s and balanced my props however when I take off it yaw out of control to the right. When its connect to the wii software it does show that motor running a little slow how trim does not adjust it, when armed and at an ideal the blades spin but the front right does shut down… any advice?
To confirm, you are using RB-Atm-01: MWC MultiWii Flight Controller for UAV (Arduino Compatible)?
Remove the propellers and connect it to the computer - open WinGUI and see what values are being sent to each channel.
It sounds like you adjusted the center position on the yaw joystick and perhaps need to being it back to 1500.
Troubleshooting before a first flight takes time and you’ll need to go over all connections (it could be as simple as a wire has come loose or is reversed).
All connections are good and the props are rotating the right way. The screen shot with full throttle

The signals being received are ok; 1500 would be ideal, but 1517 to 1522 would not cause such a major issue as you are experiencing.
The values being sent to the motors however are completely off. Again to confirm, you’re using RB-Atm-01?
Did you calibrate the sensors? Change the PID settings? The more you can tell us and show us about your setup the better we can help.
Photos are always beneficial.
I am using the RB-Atm-01. I’m using the same scripting as the vtail, I just //vtail and uncommented the xquad. I have calibrated the sensors using the joysticks. I have not changed any of the PID settings. I can post pics later.
To my knowledge the controller worked when I pulled it off my vtail. but it has taken some crashes… could it possibly be bad?
The VTails’ PID settings (and overall settings) are quite a bit different than an X quad since the rear motors are at an angle. As such, they need to provide more thrust than the motors at the front. This seems like it may be the issue.
Use the Crazy2Fly’s sample program instead (swap any motors accordingly and follow that setup).
Will do, I’ll report back with update.
Ok so I uploaded the the Crazy2Fly onto the board, the values are looking better and arming everything seems to spin evenly, however upon full throttle, the motors start to surge and there is not enough power for lift off…
We’ll need to know more about your setup; include a variety of photos as attachments in your reply here, and some specs for each component. Based on what you just said, the copter may simply be too heavy.
I got it to work like a champ! I have to move the IPF settings on the config.h file down 3 spots! Fly’s amazing now!
Excellent
