A few months ago i had to make the choice as to what ESC would be the right one for my cars. Price was the first thing which drew me away from schulzes and those pics of burned up Schulzes were the second reason. So yes those pics and threads of burned up schulzes do have an influence on opinions (i know MGMs, Castles and so on are also letting out smoke at some point).

Rhylsadar i sure am the last one who wants to argue with you about this subject as i do respect your knowledge you gathered far earlier then i did. But my point of view is why not integrating some sort of over current protection. Those of us wanting the ultimate power may have the option to switch it off at the risk of burning up their ESC. And others could switch it on with the peace of mind that overcurrent would never be an issue. Maybe this solution would be too expensive (i really don't know). I'm just thinking about someone driving a golf cart or whatever and their ESC burns up because his wheels got blocked or similar. I guess that is something you will never see because those esc have more safety features integrated. Truelly our ESCs are not meant for man carrying purposes.

On the other hand some 1:10 scale ESC have the ability to set a max current value as to reduce torque of the motor when driving on a slippery surface. This is one feature i would want to see in a future 1:8 ESC. Maybe this also suffices to protect our high priced ESCs. Our motors can take huge amounts of amperes when starting up due to their low internal resistance. This stresses batteries, drivetrain and results in possibly unwanted wheelies. Driveability could be greatly improved and especially race drivers would benefit a lot of this feature. But i know depending on the components you choose you will influence amp draw too and you can choose how agressive your setup will be by adding more cells. But the freedom you would have to tune your car from a super agressive wheellie machine down to a 540 can tamiya type acceleration seems to be very compelling to me. Maybe this small dream will come true in a not too far distant future.
