I have some yaw WKM AD8 and 4 hot motors

WKM
AD8
avroto 2814
maytech 40a ESC
14SG R7008SB
2x4s 8000 and 2x 5s 8000 batts

When i rudder left (counterclockwise from above) the craft spins easy, even overshoots a little. When I rudder right, motors make a little more noise, wants to raise elevation a little, takes more stick to yaw right, and rebounds a little left after releasing the stick.
It occurs in both in GPS nd ATTi, I didn't have it in manual long enough to determine due to limited space.

After 10 minute flight, the odd motors (CCW) which are for right rudder are pretty warm 146 degrees F (63 C) and the evens CW are around 100 F (38 C)

I have:
balanced props
checked for nicks and scratches
made the motor shafts as close to vertical as I can by eye.
balanced the craft
measured and re wrote the X-Y-Z for GPS puck

i have not balanced motors, but didn't think the 4 odd would that much worse than the 4 even.

I have not been very accurate in determining CG.

anyone had this issue, anyone solved it?
thanks,
dave in NJ

Most of my issues when encountering odd/even motor temp differences have been directly related to motor alignment. Even on Droidworx frames which are pinned and hold alignment well this issue pops up over time. Sucks mate but suggest wicked painfully accurate alignment as a start. Usually for me the excess is roughly 20 degrees. Sounds like you have over 50 degrees difference. Keep an eye on the bearings if you keep flying the hot ones.

thanks SMP,
i think you are correct too. I spent some time with the even motors this morning, and a few of them had worn their dimples, and moved more freely. I did my best to align vertically by eye, and tested with 4s batts, and when she landed I had 110 F on the odds, and 90 on the evens, so much better. I think I will be ok flying with that difference.
thanks again

Hey Great website!

Sorry if this is silly... As far as motor alignment do you mean as it's attached to the airframe (vertically) or the the shaft and motor assembly inside the motor assembly?
