schulze 40.160 alternative?

[pond skipper]

There's absolutely no doubt in my mind it's a lofty goal, but I feel pretty confident about it. I'll be doing my own prop work, sticking with the X4 series octura 2 blades. As far as packs go I won't have much in the way of options there, I'm going to have to run 2 2s and 2 3s packs in series to achieve 10s and with as little room as I have I doubt they will be able to be much over 5ah if any at all, luckily the 40063 MGM states it's capable of 500A for 5sec, hopefully this is correct! My other thought was a 60-80 seaducer with the neu 2217 1y on 10 s but was scared that it would be too many rpm even under load for the motor it's self and the amp draw would be ridiculous, plus there's even less room inside that hull for everything to fit properly, plus being able to get the CG correct with an esc that weighs in at over a pound would be a task in it's self with the smaller hull.

Here's the link to my 33" seaducer running a somewhat oval setup, it's no traxxas mind you but I think it turned out well, this was my first try with a brushless boat, even with how fast it's running now I'm still not seeing over 185a at any point according to the data logging. http://youtu.be/pLH7ZRywt9U

I would suggest you speak with Doug Smock, he probably has the most experience I know of with FE Seaducers and SAW's. The MGM 40063 is capable of 500A, but you need really really stiff batteries to crank this out.

Here are some pics I have saved over the years.

Thanks for the photos man! As far as Doug's concerned, I doubt he would be willing to help out much considering I'm basically building the exact same boat he's set all his records with for t mono, I've tried to talk to him but he's very hush hush .. I guess he thinks I may be out to try and take his record, which I'm not, but don't really blame him, if I had put as much time and effort in to achieve the things he has I'd be reluctant to share anything with someone like me either I suppose. He did offer a few words of advice for the 33" seaducer of mine which is now up to 67 on an oval setup which is nuts. Which brings me to another question, why in the world does the speed calc on here say it should only run 55-57 when I put in everything about the setup on it? It was running 63 in that video.

AJ I have answered all of your emails and PMs. What have I missed?
I'd love to see you and your dad at the Record Trials, expected you last year. And as I have told you. I'll do anything I can to help you guys regardless of the class your running.

Records are icing on the cake. The main course and why I'm involved is what takes place prior to that.

Hey Doug, I had sent you an email or two in the last couple weeks or so about building a t-mono and didn't hear back, I didn't know if I had pushed a button or something by asking about a T SAW mono. Dad and I were going to come out and watch last year but work dictated otherwise, I would still like to come out and meet some of you guys but I don't have any plans of running at any of the saw events, lol I'm not even a IMPBA or NAMBA member, dad was a LONG time ago but after the city shut down all the racket making nitro boats we pretty much got out of it till I ended up finding FE again a few years back.

The last email I have for you was on Thursday, August 29, 2013 9:08 PM
Re send it (them) if you still have questions. Always glad to help. Maybe you guys can make it to Huntsville this fall.

I'm one of those guys that you don't have to wonder if you've pushed my buttons, you'll know.

[pond skipper]

Lol I got ya, I'm the same way. I'll resend it if it's still in my sent messages, it would be nice if we could make it but that's usually the busy time of year with the company I work for, if it ends up being in October you can pretty much count me out, I'll be in Farley nuclear power plant in Dothan AL for the entire month.

I just resent them, there were 2. Let me know if you don't get them.

Hi Tyler, did you ever get 500A input current out of the 40063 without the Esc is reducing output power by itself?

[RaceMechaniX]

Hello Ralf,

No I have not, I have seen peaks on accels that were just a single data point that were over 500A, but came back to lower values quickly. However under high sustained currents over 400A lasting longer than 2-3 seconds, the power is always pulled back. This is the same for the smaller 25063, 25035 and 28026.

I have also performed a good bit of testing on the MGM's in industrial applications with similar limiting. Of course, the HBC versions are de-rated appropriately compared to the TMM versions. I have measured high continuous currents in these applications, however using regulated power supplies and conditioned water.

Hi,

thx for the info. This Phase-Peak-Current control is both a blessing and a curse at the same time...
On the hardware side there would be a lot of potential for our application.

Ralf I could not agree more. I do understand why they do it although it would be nice to increase that window just by several seconds for SAW applications. Sending you a PM.
