New 100a reversible car esc on hobbycity

[BrianG]

Let's see:

- Two MMMs: yes, I do use the fans. But I would rip them out in a heartbeat if it wasn't for that warranty issue.
- One HW80: no fan.
- Four MM's: no fans.
- Two Quark 125b: no fans.

. Just messing with you Brian. I spoken with a few knowledgeable people and they said is not that difficult to make a very strong ESC that would stay cool without fans (Easy for them to say, some work for the largest EMS companies in the world). One of those people saw a design I have in mind and it was exactly what he was talking about. Now all of them said if all the MOSFETs are saturated (I've heard this before, but still having trouble figuring out what it actually means. All know is if a driver can switch a lot of MOSFET, why not make a humangodango of a ESC, people will buy the them if one builds them) it would definitely handle what ever R/C motor available. I'm actually testing something out to see if they are right and from the initial test, I think they might be specially with a driver that I was told wouldn't be able to switch all the MOSFETs. I wish I knew what I was talking about, but I don't. So feel free to fill my head with goodies.

I still don't get why you hate fans, could you explain it please?

He just wants stuff to be designed to handle the load without needing forced airflow. If the fan breaks (and they do) the esc should be able to handle it. No too much to ask, IMO.
