Default Havoc 3S with Ballistic 8.5T won't stop overheating

I've got a Havoc 3S with Ballistic 8.5T installed in a HPI Cyber 10B running off a Ptotek RC 3300mAh 3-cell 25C geared as low as I can (16/84) (it's painfully slow). After a few minutes of running, even if I run it soft, the blue and red LEDs start blinking "possible ESC thermal shutdown", the ESC and motor are barely warm when this happens. It also ran fine on a 6-cell NiMH. I have been in contact with Novak and have even sent it in and they have been no help. My LHS also has been unable to provide any solutions. I'm getting desperate, I really need some help.

When I had the Novak Havoc 21.5 system the ESC would thermal all the time. I believe the slip said it would thermal at 150*F but when I would temp the motor it would barely be at 120*f. Ive heard of people cutting the temp wire on the sensor plug ( I don't rember what wire it is) I know you said its barely warm but have you gotten a temp on the motor?

I have no way of measuring the temp other than by touch

If you say it painfully slow and barely warming up then you are undergeared. Go up a few teeth on the pinion. It would be a good idea to invest in a decent temp gun to monitor motor temps! The best investment you can make! An 8.5 is plenty of motor and should be a handfull to drive if its properly geared.

I have also run it 18/84, 23/84 and 26/84 and it acts similarly

It shouldn't be "painfully slow" running it on a 3 cell lipo with any gearing. Can you try a differnet lipo (2 or 3 cell) or try your 3 cell with a different esc to find out what is working and what's not.

Get ahold of Novak and see what they say. I have the Havoc 3s and 8.5 Ballistic in my SC10 and it works great on 2 cell, haven't tried 3.

Yeah I cant imagine an 8.5 on 3S lipo! Should be insane fast! I ran 3S on a 13.5 and it was silly!

If thats the case the esc is bad or the sensor wire is bad if the motor wires are soldered up correctly!

Ok, pull the motor and make sure the drivetrain is free and not binding, does it roll smoothly with the motor disengaged?

Is it still running slow with the sensor wire removed?
