When for monster maxx? - Page 16 - RC-Monster Forums

I also spoke with Richard, and engineer from Castle. He said the biggest thing when it comes to the voltage rating of the ESC is braking. Using the motor brakes puts a huge stress on the ESC, and they have had to rate the MMM to 5s Lipo because of it. However, he did say that it should do 6s with the use of mechanical brakes :).

As for a HV car ESC, Richard said that it's a ways off. I think he mentioned that they would pretty much have to make a new ESC, kind of like the MMM vs. the MM.

Castle will be coming out with the switching BEC, and it will handle 6s Lipo. A higher voltage version should also come out at some point.

We also spoke with Joe Ford for a while. He's a cool guy! At the show he was the one driving the RC Escalade (power wheels). It had a 95amp-hour lead acid battery in it and plastic tires. Apparently they were killing gears with rubber tires, so the slip from the plastic tires helps the drivetrain.

Unfortunately I didn't think to ask about the approximate MSRP/MAP for any of these items.

Damn...thats a good point...we should have asked...

However, what I do not beleive has been said is that it will have an integrated switching BEC, like the one seen here, that can handle 7 amps continuous and 10 amps peak (like anyone really needs that) and will have an adjustable voltage output. Downside is that he said it will be rated only for 5S (would have liked to see 6S if you ask me), but that they will do an HV one later on that will handle more (probably 12S).

Is the switching bec going to be integrated or sold with it? if its integrated I'll get one just to do away with UBEC's, no problems with them just one less thing to have to find a place for

this is all great news. now hopefully they will be able to stick to the 3 months. now the only question is do I pick up a new neu motor now or wait and see what they have coming out with the esc? I am currently looking at the neu 2.5d 1515 to do up a 8ight-t.

Sort of disappointing, if you ask me.
I've been waiting for that thing just because of the HV feature, but to say that making such a one after the Mamba Monster Max is like designing a MMM after the Mamba Max is absolutely unacceptable. Tekin's R1 Pro can handle 5s and it's smaller than the Mamba Max.
And we have to use mechanical brakes to run 6s?!
Believe me, this is no good news, for me at least.

For me, 5s is plenty. I just hope it comes out soon. It would be nice to have a Castle in my E-CRT rather than the unreliable ESC I've got now. I know they want to release a system but if the ESC is done, I hope they consider shipping it without the companion motor. They can always release a system later.

BP-Revo · 04.02.2007, 01:18 PM

Crazy, refer to the word right in front of the bold "switcinng" in my post.

5S is plenty for me as well. I'm happy to say the least. I'm probably going to run 4S anyway, but I want the MMM for the extra current capability for the 1950/6 Hi-Amp.

jhautz · 04.02.2007, 01:20 PM

If its sub $200, can run 5s reliably, and can run 2 or 4 pole motors and doesnt need any secondary heat sinks or fans its a winner in my book.

It will be great for everyday running.

I will wait for the HV version. But in reality the HV is really going to be for a very select crowd. The general basher/racer will not need more than 5s. The folks around here are just a little crazy with the power. (crazy in a good way :p ) Definately not the norm anyway.

Thanks and sorry, I have a bad habit of speed reading posts

captain harlock · 04.02.2007, 02:32 PM

Well, I might just keep waiting until the HV comes out.

BrianG · 04.02.2007, 04:20 PM

I still think they should've at least made it 6s capable. Many people use layouts that have a battery pack on both sides (emaxx, buggies, truggies, etc) and it's nice to keep the weight balanced. Granted, the MM will probably be able to go to 6s, but won't be advertised as such. There must be a big price difference between low voltage FETs and higher ones since there are few high V ESCs and the ones that do exist are pricey.

GorillaMaxx360 · 04.02.2007, 04:54 PM

i am mainly waiting on the mmm motor to use with my 125b. hope it is out by mid summmer

Metal said it was because of braking causing high spikes, I think the price for high enough fets and caps might have killed the budget aspect of the ideas the mamba packages were founded on. I hope the HV has all the good points on the mamba series, but the HV that everyone wants. The more i see on the MMM the more i like it, I hope the link gets better though

I personally have never used the CC link, but then again, i only have the mm 25....
Other than that, with all the issues i have heard about the link I would hope they cure this problem.....MMM should be great, i just fear that it will take longer than anticipated....

Its not the mamba 25 or any other esc in castles lineup, all the forum threads and problems i have seen are with the mamba max, which strangely is the only one with a usb jack and not plugged into the reciever wire

I would believe the problem with the driver in the esc if the esc never worked on the computer, the newest one did just that, but run once before losing neutral, but the oldest one had been programmed several times in the n=early year i had it till V2.23

As I have said before to all new people, I love the mamba max system, I'm just concerned about the programon the computer
