Castle - Make A Special Edition Monster

I know I'm not an engineer and what we think off might be possible in our heads, but not in true life application. But since you are working on the stackable Monster, when will the HV one be available? Will you be having other guys put the controller to the test or will it just be team drivers?

I gotcha -- what we really look for during design is the silicon (or RDSon) to footprint ratio. So if you calculate milliohms / mm^2, you can compare silicon ratio pretty directly from FET to FET. Right now it's pretty tough to beat the 5x6mm leadless packages for up to 100V.

I haven't completed the layout of the control board yet -- I'm using a 72V maximum input switching BEC for the HV version of the board -- But I'll make it so that an external BEC can be used (Brian!)

Ok, so basically being able to switch all the FETs, it would be possible to get a lot of FETs in a PCB that is a little larger then what the Monster Max uses. So a ESC that can go as high as 400A is possible to keep things of the safe side if one wants to use a Neu 1527/1D, 2215/1Y, 2230/1Y or a Lehner 3080-5. Patrick, I would put a high priority on such a controller . We are hungry for it.

Well, the design I'm working on now should handle any of those motors with ease. Versions with 60 and 120 FETs will be first.

It won't be "moderately priced" like the MMM.

Around $300 would be really hard to keep in stock. Please add me to the top of the list for that one and I can send you payment right now for 2 maybe 3 units. I'll be the guinea pig if any problem arises. I wouldn't mind testing a units as well.

I'd buy a couple. I agree $300 is a good target, but I think they'd sell at a price higher than that.

Yeah, just look at Schulze's. Talk about expensive! $300-$400 for a "proper" 200A 12s ESC is more than fair IMO. Heck most of us were paying at least $200 for a 100A 4s ESC before the MM came out!

Schulze price is not realistic. How can they have a price of $600+ for the 40.160 less then a year ago and now the thing is $700+. Maybe they think they have a super controller, but I just can't see how it cost that much. If anyone can come up with an answer of where they get that price from please let me know.

My thought is to look at the best competitor in that HV ESC range - the strongest competition is the MGM 9032 and 12032 coming in at $400 and $450 respectively. Their hardware is solid, their software is horrible.

An ESC that could handle 10-12S, w/ or w/o BEC (I don't care really, but maybe better without - just another piece to break), with a built-in USB port (I think that is one of the best components of the MM compared to the MMM - very convenient to program not having to wear out the 3-pin connector removing and re-inserting it into receiver all the time - and about 5 times faster reading/writing settings than the Castle-Link), and with Castles ease of software programmability.

I would pay the comparable of an MGM controller for that!

What would be unmoderately priced be?.......

Well,

Probably around $275.00 for the 60 FET option in 8S and 12S versions. Around $375.00 for the 120 FET version (40V-8S or 60V-12S.)

8S - 60FET will handle in the 200A range (continuous) and 1000A (surge)
12S - 60FET will handle in the 125A range (continuous) and 500A (surge)

8S - 120FET will handle in the 325A range (continuous) and 2000A (surge)
12S - 120FET will handle in the 200A range (continuous) and 1000A (surge)

Most likely we will release the 12S version first (stock FETs) -- followed by the 8S version.

Sound OK?

I'm first inline for pre orders . I would love to test one too .

Sounds more than O.K. Where can I pre-order 4 of them?

Any plans for a HV CC Bec to go with them?

Now that's what I'm talkin 'bout

Exactly. Europe will be playing catch up when those bad boys come out .

I am good with that price........still cheaper than the MGM HV models
