Hi helicopterers, I don't have a heat meter to measure the temperature of the motor of my mini titan but the thing is that on the first battery all looks fine, after the second you can touch the motor with your finger easily, but after the third battery you can only touch it for 2 seconds. It burns a lot. I have to leave it for 15 minutes and then burn 3 more batteries. I am running a yge 40amps esc which remains very cool no matter how many batteries you use. Is this normal for a 450 motor? Or something else may goes wrong? The rotor head seems to rotate as it has to. I want to change the bearings of the main shaft though. Just to be sure. What do you thing about the finger rule as it is mentioned for a motor?
