Mojo 280 problem
I have one Mojo out of many that Yaws CCW on take off and will drift in flight at times. I have gone over it several times as well as one of our other techs and all seem normal we have even changed the Naze 32 board and tried different transmitters. The ECS have been calibrated and changed props. The firmware has been updated nothings seems to effect the issue. It is being flown on a Spektrum DX18 with a DMSX sat.

Hi! I have one of these that's always flown perfectly, but I've now heard of several people having yaw issues with these when all the electronics seem okay. With these having round arms, is it possible that one of the motors is slightly misaligned? Since the frame is preassembled, I haven't ever looked to see if the arm or motor mounts have some sort of alignment lock.

There are no alignment holes, slots, marks etc. You have to level each each one not really all that hard takes a little time. A friend of mine pounded my Hyper 400 on his first flight and I did the rebuild.
One other thing to check is looptimer in the cli setting by default it is 3500 you might try lowering it a little and see if it helps. It controls how fast the controller samples and update things. My mojo spins out baldy with the much higher yaw rate I use. Lowering that to 2700 went a long way to fixing it. Finally go into the radio tab in baseflight and make sure that with 0 rudder the value is exactly centered. If you you will need to adjust the trim in the radio. I have not had that on either of my Hypers or my Mojo but have had it with other quads. It shows up as a slight drift or yaw depending upon which channel is slightly off.

I resolved it but????
Ok so today I tried the servo balance in my DX18 and bam it is perfect. I also noticed a little drift to the right and forward. I adjusted the servo balance on all 3 and it is rock solid. I think I am going to save these settings then make a new model and try some of your suggestions to see if that fixes it as well. Also this is a brand new machine so it should have been aligned pretty good but who knows but it looked straight.

Glad you got it sorted! Some good info here for future reference. I think you'll really like it now that it's flying right.

In the baseflight GUI there is a tab labeled CLI select that tab. There is a command line entry field where you can enter commands and view settings. You have to use the save command to make your changes persist.
