I also have 4 voltage regulators (1 for each servo) with heatsinks and they are pretty hot too

I dont think the regulators are the main problem. They are getting quite hot but they have heatsinks on them

The regulators arnt getting very very hot.
What happened? are they getting cooler?

Can you provide the specs for the motors? Make and/or model ?
