Where/How should I put the MMM switch in E-Revo - RC-Monster Forums

Ok, I know most of you guys don't have yours back yet, but of those that have an E-Revo, where do you suggest to put the switch? I have seen a few comments on this a while back, but there weren't many posts about this. Thanks!

switches ? we don't need no stinking switches, %!^ches. :D

I honestly don't know, since I don't have an e-revo. I usually tuck the switch away with a ziptie that's holding the ESC down. Needs to be accessible, but I rarely use it. Switches are a good way to forget to unplug your LiPo's....

anywhere it fits....

I just realized something...I'm used to the Traxxas style ESC's which turn off once you unplug the battery and then you have to push the button again to turn it back on once you plug the battery back in.

So, in this case, I won't really need to get to the switch that much since it will pretty much be "on" when I plug the batteries back in! Ok, that helps a little bit, but I'd still like to hear from anyone with an E-Revo with their thoughts.

**puts down shovel**

Well, FWIW, I stuck my switch to the side of the esc, on the part covering the capacitors. For the Erevo, I would suggest somewhere near the edge of the chassis, so you can just poke your finger in there and flick it back and forth (smut intended).

I would suggest using the on/off switch though, otheriwse you will get that big spark upon plugging in your batts each time (the fan and brainboard discharge the caps if left turned on after removing batts).

That's really good information! Thanks!

what about cutting a small rectangle to mount in the black "cooling" fins ? I dont actually have an erevo so i dont know the size relation, just my idea lol

Hey, I appreciate your comments, but shouldn't you be out testing the HECK out of your recently received MMM? I would appreciate your comments on that ALOT more than the switch location! LOL

BTW, I think you are the first on in AMERICA to get the (non-beta) MMM up and running! Get going!

LOL ok ok the batterys just beeped. ill go play with it if you insist LOL BBL

Hmm. My setups all spark when I plug them in regardless of the switch position. Do yours not ?

Are you sure it actually stops ALL current draw? The switch on most ESCs simply disables it, but the circuits still draw a little current (probably well under 1A), which is a good way to deep discharge your batteries if left plugged in for a while...

Well, the ESC still draws current if you leave the batteries plugged in. My main point was that you can't plug the batteries in and go without pushing the power button on the ESC, whereas on the MMM, if you left the switch on, you could just plug and unplug the batteries to start/stop power and therefore the switch position wasn't too critical to have easy access if you just left it in the "on" position all the time. However, suicideneil points out that there is a pretty good spark when plugging in the battery if you leave the switch in the "on" position, which can't be good for the batteries or the ESC.

Cool.

I've found that if I leave the esc turned on (by mistake or accident after knocking the switch), when I go to plug the batts in after any length of time, the sparks happen (and my trousers turn brown). I also noticed, and everyone will IM sure, that the esc tries to arm as its powered up; not having the batts connected fully as it does this causes the esc to start arming, then stop, then start again as a proper connection is made. If you plug the batts in properly, then turn on the esc, it arms properly as there is no intermitent current (sparks) between the batts and esc plugs.

Make sense?
