I'm guessing that Joe means that they won't warranty their CM36S motors on 5S, which of course makes sense. Not warranting the 2200kv on 5S (which is what I'll be running) would be absurd, seeing as they recommend that motor for 6S usage...:neutral:

A 50mm Medusa is a little on the small side for the Esavage - but it isn't THAT far out of whack really if properly set up and used. I use a 2000kv 60mm Medusa in my ERevo (a couple pounds heavier than the ESavage) - I also know how to set up my car and check temps, etc.. The E-savage is like a slightly larger 4wd stampede in size - noticeably smaller than an emaxx or ERevo. Tha savage flux is a different story.
I think the real message is that if the non-Castle approved motor fails and takes the esc with it, it isn't covered under warranty. The 50mm Medusa is on the small side of ideal for that application, and is therefore more "prone' to failure vs. a more appropriate motor selection. I think the motor would fail long before the esc in this instance, though a failed motor can take the esc down with it(depends on how it fails).

I think it all goes back to gearing and speed. A 50MM on an Esavage is a bit small, but what if it were only geared for 25mph. You would have more torque than the original setup and about the same speed. The problem because that people go with the 50MM, decide its ok to run 6S or gear it for 50mph on 4S and then you are going to have problems.
I think the bottom line is if you know what you are doing you wont Smoke the MMM and you wont have a problem. 99% of the people out there dont know how to do these calcs or have a good understanding about running these systems within a sweet spot for voltage, motor size, kv.
I'm glad the castle came out with the combos and put restrictions on battery and motor. It helps everyone else have a successful run without the smoke.

My interpretation:

Non Castle motor fails (in spec / out of spec) and takes out MMM ESC - Not covered for free - Pay the flat fee
Castle motor run in spec - Motor, ESC or both fail - Covered for free in first year
Castle motor run out if spec - Motor, ESC or both fail - Not covered for free - Pay the flat fee

Seems bloody fair to me... Castle will give you a new controller for 50% of retail for life regardless of what you do to it...

Thank you Castle... I don't see this as a change from anything in the past...

Both of the MMM motors are quoted as 6s suitable and hence I believe will be warrantied as such - I think this is one of those miscommunication occasions.

PS To anyone running a "out of spec" setup - Is anyone actually going to change there setup or just "miss submit" their motor spec on the warrantee form...

As I see it this is just a way of Castle trying to steer the masses (a couple of forums to remain nameless) to use an appropriate setup for their cars.


Lets keep the drama in the theater...

^^^What Arct!k said^^^

Seems all common since to me.

what if you are using a neu? :neutral: arent they the cream of the crop motors?

as long as it is a 1515 size it will exceed the 68mm length

I would guess that it still depends on your setup. A 1509 in a REVO would be a no go! If your running a genuine 1515 1Y and it fails I would guess your ok. I really don't know though

This is pretty much BS in my opinion...

I think they are hedging against stupidity, and I can't blame them.

Before throwing CC under the bus, maybe give them the benefit of the doubt.... that they do have great customer service, and will continue to take care of their customers. But there must be a line drawn at some point. They can't continue to blindly warranty any and all MMM failures when they have reason to believe it was not the fault of their product.

The problem is... how do you/they know exactly what went bad and what's to blame? I don't know the secrets to diagnosing smoked escs.... I'm sure CC tech can at least make an educated guess by inspecting the damage.

Anyway... don't be too quick to flame a company that has always bent over backwards for you up to this point. You KNOW there are a lot of retards out there buying Castle products. Some of these people should stick to radio shack cars... lol

I just think it needs to be clearer, you can't compare a Hobbywing 50mm can motor to a Medusa 50mm can motor.

My set up of a 60mm Medusa motor on 4s in a 1/8 Buggy, is that a warranty risk?

I know not to put a 50mm can motor in it, so I accept that if I do that, hey, my bad!

But if I put a 50mm motor in a Tamiya Mini behind a MMM I wouldn't consider it an overload (well except for the gears in the car....)

I was just making sure that CC was warranting their esc and motor on 6s...

Would be nice to have it black-and-white... they must have good reason to give themselves a little flex to make a judgement call.

I don't envy Joe/Castle for having to make the call on this stuff... that's for sure.

your right, but castle keep telling us that they are bullet proof and that the v3's arent failing, then they say that if you use a smaller motor, you lose your warrenty

something doesnt add up.

Well, you gotta use some common sense. It would be like putting the MMM as the powerplant in a Prius and complaining the motor and/or ESC blew. You have to use it in the right application. Using it with a tiny ~50mm motor in a heavy 8th scale application geared for any decent speed is asking for trouble.

And it would be hard to simply put a list of "acceptable motors" because even those can be the wrong motor depending on the application. Even the bundled CC/Neu motors could be too much for the ESC if used incorrectly. Just too many factors to make a hard rule.

It simply sounds like they are diplomatically saying "Don't expect us to be accountable for your idiocy".
