Castle - Make A Special Edition Monster

[jhautz]

They have this one already though... Just put the MMM brains on the MM power board. they could have that one done by the end of the month.




Actually... It sounds like they have done it already with the MM Pro Patrick mentioned. Just dont take off the fets they were going to remove to keep the price lower.

That's why I mentione the smaller FETs. You can basically fit 2 times more in the same space.

Hmm. Makes me wonder when we are going to see an integrated solution with the silicon for all the FETs in one package. large power input and motor output leads and small gate drive leads. Seems like it would sove the problem of getting things to fit...

I'll look into making a 5s capable control board for the MM -- if you think that will be sufficient.

Thanx!

Add a switching BEC and true 5s capability to the mm controller and you have a winner imo. The size is much more ideal(particularly for buggies) vs. the monster and the controller with a fan is plenty capable with some sense. I have a few of these MM controllers in buggies and truggies - running 4s and 5s. With a fan, they have never thermalled or even gotten above 130F even in hard use. I do have to discharge my 5s packs a bit to get them to work well (about 20.6 volts or so).
In reality, I think the 1/8 use less current on average vs. a comp level 1/10 touring car in race conditions - less traction and more voltage. The spikes are higher, but the average current is lower. :)

I'm on board. MM, 5s capable and Switching BEC. Same footprint as MM.

Patrick, If you build it they will come.

Or how about a RC-Monster - Special Edition MM with these specs. I kinda like the sound of that.

I actually spoke with Lee and one of the Castle engineers about OEMing just such a controller at the RCX show - they suggested the mamba pro was just this(except I would prefer an additional lead for link programming and fan power - easier to unplug the fan for programming vs. messing with the rx) - they didn't mention a lower current limit, though(I agree with the sentiment that this lower power handling is a bit of a disappointment). :)

That's a really good idea. When I did fans on my mm I just used a 3mm tap into the hs and ran a lead back from the bec (4S/5S use.) This already done cleaner w/ a switching BEC would be +++.

The usb frustrates me as well. Its a great idea in theory, but the plug never seems to be in the right place. A little dongle would be great.

The MM works quite well on smaller or overpowered 1/8ths. The trug I'm about to do now I'd really like to run 5S on, but there is a gap in US controllers able to do that w/o being overkill. I don't need 200A capability, but 100A and 5S would be king. I can live w/o 6S.

Would be perfect for CRT .5's & buggies - To be honest all my vehicles.... x1cr, 2 crt.5's, hyper st, g3r

Please do! And give me enough advance notice so I can sell off all my current MMs to be replaced 1:1 with 5S MMs.

[DLS II]

I think 6s-A123 would be nice. On my current build I'm going to try to run 6s A123.(MP-6 with Rimfire 42-60-600 outrunner in place of center diff) To do that I'll have to use my Schulze 18-61K and hope it will hold as I know my MM won't handle the voltage. Don

[MTBikerTim]

Your Mamba Max Pro sounds perfect except that the current handling ability will be down on the Mamba Max. I am with the others and think it would be better go keep them the same. I am sure there are good reasons for doing it but I would have thought the cost savings made by replacing the MM with the pro manufacturing and time wise would offset the cost of the extra fets to keep the current handling the same if not better. The only other thing I would like to see on the MMPro would be protected capacitors like your newer escs.

Can't wait to see whatever comes out.

I agree with 5s capabilities with MM.....

[Happywing]

This is sounding like a controller I would like to have. I've run the MM in my 1/8's for quite a while now and they do great. I've always said, "if it was just a tiny bit more robust, it would be perfect."

[Dagger Thrasher]

Sounds good to me. The MM Pro sounds fantastic. All I'd do, like everyone else has suggested, is keep the current handling at the same level as the MM's and sell it for a slightly higher price...which would justify its "Pro" tag IMO. It'd be a great controller for 1/8th buggies and powerful 1/10th setups, and then there's the MMM for truggies and monsters. Perfect line-up!
