I See, what I was trying to say was the cooling fan is dependent on the power given to the motor and not the temperature. But this is wrong anyways. This is when the fan is wired to the output lines, which can lead to overheating.

I misunderstood what I have read. You are correct. The fan should be wired onto the input wires which will turn the fan on all the time at full power.

Wouldn’t it be difficult to monitor the temp while its in the rc car. I just wouldn’t have piece of mind having that esc on my car. I would be always worried that it will overheat.

Maybe you can remove the fan and put some heatsinks on them. Not sure if you can connect the FETs with the heatsinks (it might cause a short) I think you might be okay since we usually only run 6 – 7 cells on our rc cars, that’s 7.2v to 8.4v and the victor 884 can handle up to 15v. Not sure about amp draw with rc motors though which is usually what causes the heat build up.

Don’t they cost over $100.00 retail. With that amount, there are a lot of multi-featured ESCs in the market that has thermal and overload protection(breakers). Other features to consider over a robotics esc, radio priority, polarity protection, programmable etc.

This is just my opinion. To add, Its always cool to have something different and unique from the usual in the RC world.
