I put the heavy lift conversion on my f550 (complete dji setup package) with stock dji 2212s and impacted the winding so I'm looking to upgrade motors to larger 40s so I will have them when I build my next rig. I have a large collection of 3s batts so the motors need to be compatible!

Motors I am looking at-

tmotor u3
tmotor 4006

are these compatible with 3s?
