Not sure if this has been discussed, but I've conducted 6 test flights of my Y6B and after running for 10 minutes in Loiter each flight I've felt the motors and observed the upper motors are relatively cool and the lower ones hot enough to fry eggs on it. Why are the lower motors running hard than the upper one? Is there something I can do to ensure I don't burn up the lower motors? Uppers are running 10 x 4.7, lowers are running 11 x 4.7 propellers.
Appreciate some insights and recommendations on this topic.
