Rock Crawler
All right all right. I bought one.

The AUX wire isn't needed in most instances and especially not a slow, brushed crawler IMO. It's an awesome feature, but not a must have on a slow, dedicated crawler/scaler.I have two WP 80s and they are FANTASTIC ESCs. They just work, are water friendly, stay cool on 3S, are really cheap (not just affordable), small and programmable. They also have great low speed resolution, are really responsive and have instant reverse.
All HW have to do is offer a switchable AUX for say drag brake like Castle has done and this will be the defacto brushed ESC for 1/10 brushed setups...that if it's not already. I guess the question is 'why would you buy another brushed ESC with this now available'?
Somebody posted their settings somewhere on this thread. I don't remember mine offhand, but I can share when I get home if I remember to do so.Hey guys, finally bought one of the 1080s, was wondering if some of you would share how you have it programed for a scaler? For things like drag brake, start up, and mid range performance. What is working, what isn't working? The info would help a bunch of us. thanks

A lot of it is personal preference as well.Most of the settings are already setup for a crawler.
I only changed maybe two of the settings when I set mine up the other day.
One was the Bec and the other I cant remember. Lol
Agreed and I'd add experimenting with the frequency and freewheeling settings. They recommend freewheeling in a certain position for crawling in the manual. I honestly have no understanding of what this freewheeling feature does.I think the things worth checking out are the specific options to this ESC, which I haven't tested yet myself, like these options:
How much difference between the "initial start force" settings can be felt? (Option 4)
How much difference between drag brake rate can be felt? (Option 10)
How much difference between start mode/punch settings can be felt? (Option 12)

http://www.rchelination.com/great-esc-shoot/ said:Inside your ESC, there are a set of switches call field-effect transistors or FET’s that turn on and turn off to allow current to flow through each of the three phases of your motor. These FET’s stay on when you’re at 100% throttle, but when you set your throttle percentage to something less than 100%, they have to switch on and off many times per second to “chop up” the current into tiny chunks that can be added together to give you the lower throttle output that your transmitter is asking for…
In normal operation, when a pair of FET’s (called a bridge – there are three bridges with two switches per bridge) switch off to stop driving a phase of your motor, there is a “freewheeling” current that continues to circulate in that phase for small amount of time. This current is forced to flow through a diode that sits in parallel with the lower FET in that bridge. Since the diode has a voltage drop across it, heat is dissipated and it warms up. For example, if we’re pushing 60A at 50% throttle across a FET body diode whose forward voltage drop is 0.5V, then 15W is being dissipated in that tiny FET! Ouch…hot!
Now then, active freewheeling comes in when, instead of running at partial throttle through the FET body diodes, as one FET switches off, the “freewheeling” diode switches on to allow the “freewheeling” current to flow through it instead of it’s body diode. Since the resistance of the FET is much much lower than its body diode (usually around 5 milliohms), much less heat is dissipated. For comparison, if we take the same situation as above, but this time flow our 60A through the “freewheeling” FET, we get a total power dissipate of 4.5W! More than three times less than the non-active freewheeling ESC…
Ok, so if by this point, you’re lost, I’ll just feed you the punch line…ESC’s that are equipped with active freewheeling are able to operate over a wider range of throttle percentages due to the more efficient switching methodology that is used. This means that you can run lower head speeds without having to re-gear or worry about your ESC blowing up! Because the ICE2 doesn’t have active freewheeling, it can only run safely above the 55-65% throttle level, whereas the others can go as low as 30%.

I've been beating my wing(1080) for 4 months now. The thing is a beast. I've since converted all my rigs and even a few touring cars over to the 1080. Just ordered the MST CFX kit and a 1080 will be going into that, as well. Yeah, I love this thing!

Thank's for being the guinea pig! Are you doing that in attempts to save weight or size or just curiosity?Well, I de-cased one. It's a total pain in the ass. I'll post more pics and details later but here's the result. I was right, the entire inside is filed with conformal coating.
