The temps calculations is an estimate only, and not ALWAYS the case. Another problem could be a connection somewhere as well. Also, you are running a ubec correct?

Yes, I have heat modifications to help the MM run with a 25C 5000mah 4S pack including a Novak cap, fan on the heatsink, and CC-BEC with red wire pulled from the esc plug and fan wired off BEC.

With my config the motor rpm is just above 35k. Not sure if that’s related but may be close to the ceiling for a Fieago?

Ok. Then I would try the 16T, or even the 17T. Also make sure your connections are ok. Your RPM are right where they should be. I don't even run a cap with my MM on 5s. I do however have a fan on it. :) The only diference between what I run and what you run is the motor. I ran the 10xl on 5s, which now I ahve the 9xl which i have not run. But I run 16T/51T, and everything is happy.
