Lol my thoughts as well!

Thanks for all the input guys, I think I may just go MGM from the get go and save myself the heartache and wasted money.

Good call!

How water resistant are the MGM controllers?
I have no experience with MGM, and for my (sport) applications this would be important, otherwise I would have no problem spending the money if I only have to do it once. I will say though, that as one who has had a smokey and smelly learning curve with esc's, my Sniper burnt 2 Hydra Ice 200HV's, and a SF 240HV, put and SF300HV in and it has never skipped a beat, but I'm well within the 300 amps. You just have to make sure you get the most current software, as some SF's wouldn't recognize full throttle on my Spektrum TX until it was calibrated at 100% then turned up to 120%. Hifei denied it was an issue as I tried to get the 240 replaced, it failed from heat, (which is to be expected somewhat when it only runs at 70%), right up until the day I finally caved in and paid for the replacement. Then they gave me the software update that corrects this.

mgms are great i have 2 have had 3 one burnt up completely under water in a 4x4 slash that hit a puddle about 4" deep that i didnt think was that deep and i think the motor shorted burning the esc and i was told i could replace it because the boards were burnt for 60% of retail and for the other one i had serviced for over pushing it i was charged 50 euro well worth the repair price considering any esc beside the t180 cost more. to put things shortly repair and communication 1st class(mgm). Product first class, would buy again, i own some schulzes(5) and mgms(2) and wont be buying more cheapy escs unless they are one of the t180s that have lasted me years. Btw i own 2 sf120 v1 still working after years also

Can anyone tell me what the actual limit stations of the schulze 40.160 is and what makes them so sought after by SAW racers? Does it have something to do with internal resistance or something?

[RaceMechaniX]

There is no exact answer. It depends on the junction temperature in the FETS, battery quality, connector quality, ripple current, motor load, cooling, cable inductance and many other factors. Their nomenclature is pretty accurate, i.e. 160A continuous with adequate cooling and 200A for several seconds. Of course these can be pushed harder, several of us have pushed over 500A through them for several seconds.

IR is part of the equation, but in the old Schulze the particular benefits are its simplicity, high copper content board and good design. The newer 40.160wk's and 32.200wk's have lower IR than the older 40.160wk anyways.

There are many good alternatives, but you have to design and select around the entire system.

I don't understand... the thread started out with you wanting an alternative to the 40.160, now you're questioning why anyone would want it in the first place?
This is an odd thread. There have definitely been a few things said that I don't agree with. However, not everyone will agree on the best way to do something, and the odds of you finding out how to be competitive at a SAW event by asking the forum are quite low.
I'm not trying to be negative, just honest. With a question like this, you will get guys with experience that give you mixed feedback, people with no real experience that swear they have the answers, people that make recommendations based on what they have seen on you tube, and sometimes people that seem to have their own agenda. (I'm not really describing anyone specific here, just speaking generally).

The reality is that if you want to be capable of setting a current SAW record, you've got to beat the people that have already set them... so you need to figure out something that they haven't. People who really do have experience might try to be helpful, but in the spirit of wisdom they are not going to provide clear cut answers (see posts by fluid and race mechanix). It's just not possible.
Between a few of us in this thread, records have been set with every controller mentioned, with the exception of the hobby king yge knockoff that someone linked. There is no magic bullet.

[pond skipper]

My apologies, I simply wanted to know if there were any controllers out there that are as "capable" as the 40.160 because they are becoming seriously scarce and I'm pretty sure if I could get ahold of one and something happened to it, getting it repaired would likely be tough, in regards to my second question, I've never had any experience with them and didn't exactly understand why exactly they were so revered by straightaway guys exactly, especially with a. 160/200A rating when I knew there were more amps being pulled than that.. I apologies if I offended anyone, I just wanted to learn something new that may possibly help me go fast in the future.

AJ, I didnt find anything you said offensive nor did I think any of your questions were off base. Keep an eye out for a SAW's event in Huntsville later this year. You will learn 10x more attending an event than you will on the boards. The competitors wont share all their secrets but people are a bit more free with info because everyone tries to help each other out.

Yo Keith, you need to lay off the Red Bull late at night bro.

....I'm pretty sure if I could get ahold of one and something happened to it, getting it repaired would likely be tough....

Not at all. A club member just sent in a dozen 40-160s to Matthias and they were repaired/updated quickly. It did take three weeks for the mail to return them though....there was a high pucker factor before they finally arrived.

Well thanks guys, I appreciate the insight and thank you chilli for having my back on that one. Looking like my best bet will still be to go with MGM, just need to figure out weather or not the 250A version or the 400A version will be better suited for the task, I guess I should clarify that I'm not actually out to break anyone's records but to beat my own personal best speeds, I'm not a namba or an IMPBA member, my father and I use to run at municipal park here in Mobile Alabama back in the early 90s and always did monos, believe it or not he's still got his red metal flake top white bottom sightler hull and I'm probably going to give him my castle 2028 and hydra ice 200hv just so he can get it running again just to have fun, what I'm building is a 90/100 seaducer with the same color scheme as his boat and my p-mono seaducer, I'll be running a neu 2220 1y on 10s 1p and have to play with props to see where it's happiest. Hopefully I'll be able to break 90 but this is simply something me and him do just to have fun and enjoy, and we wanted to build a big FAST mono, mainly just to see if we can. I know it will be limited to just a few fast passes but that's really all I wana do anyway.

[keithbradley]

Perhaps the tone of my post was not clear...I definitely wasn't offended by anyone's post, and I really don't understand what prompted the red Bull comment.
My post was pretty genuine...I would be interested to know what prompted you to make the red Bull comment chili (in the spirit of clearing up whatever was misunderstood).

Pond Skipper,

Now that you mention the application and motor we can make some recommendations. I can tell you that is a lofty target, but very possible. Normally a 25063 MGM would be a very good choice for heat racing, but for SAW you want to opt for the higher power 40063. I have used both of these ESC's and have had good success with the 22 series Neu's, 20 series Castle's and 22 and 30 series Lehner's. A 1P set-up will be hard on the batteries so use the largest capacity, best cells you can get and use very good bullets. You will be up in the 400A range with a competitive prop.

On the good side, the MGM's have reasonable safeties built in so unless you do something really silly you will be OK. On the bad side, you may be well over 400A with a sticky, wet or poor prop choice and the safeties will not let you push through.
