I don't know what your point is bomb, but i don't like your approach nor your attitude. (this is my opinion, judged on other posts you made, and this last one)
I won't bother going into this useless discussion with you. (with you it's more of a monologue IMO) To remind you; I told you that preventing an overgearing is better than running it. But there is a difference in OVER gearing and overgearing.
BrianG has made a neat calcultor to help you preventing overgearing. (if you used it, you probably could have saved quite some of the controllers you listed) (it also includes a neat warning feature if your motor is running at a high RPM)
But in
this movie i had my savage geared 26/47 on 16 cells. (115 km/h) Guess what, the controller survived.
The reason why controllers burn, due to overgearing is because they current it needs to handle is too big. It doesn't overheat, it simple hasn't got time for it; it's just used beyond specification. if a fet is pushed beyond it's specification. Another problem with fetts and the earlier controllers, is that when they where rated at a 20 degree C temperature. If you take a look at the datasheets of most fetts, you'll see a drop in current it can handle when the temperature goes up. if a fett does 50A at 20 degree, it's not odd it does a 15 at 60-70 degree C or such.
As far as i can see, the setups you used aren't very capable of high currents.
I am sure that if i used 2P 16S GP3300's on that setup (bigmaxx/18.97) it would have burned.. No doubt..
If you would have came here in the first place and asked what gearing you needed for the listed vehicles many others, including me, would have helped you with picking the right motor and the right gearing.
Now, if i ever need help in ruining a controller, i know who to contact now.
this is a nice guideline to determine if you are on the right track.
