Higher pinions = safer MMM's? Or no? Someone's lying....

There is a HUGE difference between Load and overvoltage. We are talking about the load, it seems the ESC is more than capable of handling that. What we are talking about is damage to the ESC through braking.

Here is where I have a problem with this. The unit is rated for, but only NOW is there ANY mention of batteries other than "We recommend A123 or other good batteries". No one knows what the specs are and there isn't any good info out there regarding this issue (except here). To me the manufacturer should have in place a way to deal with this issue regardless of the batteries used. Hell the ESC is rated for use with NimH for gosh sakes and they have a much higher resistance than any of the Lipo/Lion I have tried. You can't put this off on the customer when the manufacturer doesn't have anything on their website (until now) about any of this. The FAQ has grown a bit but when the MMM first came out there was no mention of "Hey this will happen if you use inferior batteries".

Not everybody that buys these things go to forums. It's the duty of the manufacturer to inform the public when they buy, instead of providing a pamphlet, with a little humor. Granted most people aren’t going to read it, but at least you provided it.

I work for a manufacturer and know first hand of the stupidity of some customers. I have been flown out all the way to Halifax, Nova Scotia (from Houston) for a service call because they said our system didn’t “work”, I informed them that they needed to have the scale on it’s own support stand and it needed to have X-bracing since it was 10 feet in the air. I had 7 Mechanics (I was about 23 at the time) all old timers that were very pissed with what I had to say and said I had no idea what I was talking about, and challenged me to “show me where it says that in the book” I opened it to the page on construction of the frame and all the other information pertinent. They grumbled and I explained how to build it and make sure that it was X braced. I came the next morning and there was a stand but the only supports that were knee high and about 8 feet off the ground in an H pattern. They still said they were having problems, and I could walk up grab the posts and shake the system and it would wobble for about 5 seconds. I said well you didn’t follow the instructions, an argument ensued and I asked if they had a couple 10’ sticks of Angle iron and some welding vice grips. I set one up on one side diagonally and the other on the other side diagonally in the other direction. Then tried to move it and it wouldn’t budge we started running bags and all of a sudden everything was perfect. So I know customers don’t like to read manuals, but I have been in the market for a larger ESC for a while and researched for more than a year now and there isn’t any real info out there from the manufacturer. I downloaded all the manuals, I compared and I ran into this forum.

Now I have an AAS and a very mechanical background, and I didn’t know till recently what was going on so how the heck do you blame Joe blow off the street to deal with this kind of stuff. Hell anytime I or another member on this forum are in the LHS we are the ones who get asked the questions by the staff, how messed up is that?
