Any chance we will see a 12S Car Esc soon?

So when will the Mamba XLe 50 be released?

Well... i was on the market for a 8s ESC.
But i will wait then No worries.
Glad they are doing something..... this is the time right now for something in the likes... high end ESC's are doing it for years... so a major player in the domestic field should enter in this level son... or China ones will get there fast and then

Don't get your hopes up on China to make us any decent HV car controllers, they haven't even bothered to copy the Mamba XLs right? The market for this is really too small to justify a lot of R&D effort, if any. Also explains why there isn't any innovation going on in this area. Deep pockets will get an MGM, and at lower price point there is not any real alternative to the Mamba XLs.

As long as the typical RC kid thinks 6S equals "brutal powaaah", HV car options will stay very limited, unfortunately.

Oh, they actually did bother to copy the Mamba XL :)

What makes me wonder is, why did they put the current sensing shunts on it? I think it doesn't have PC connectivity or datalogging.

Ah, I underestimated them, seems they also copied the frying part! :D

Where's those Current sensors, is that the green things at negative lead?

To be able to control maximun current ....

Not sure if and how max Current can be controlled with that ESC, but technically you don't need Current sensor to do so, as the Current follows from the Voltage drop across the motor anyway. At least that's how it seems Castle implemented their Current/Torque control: http://www.rc-monster.com/forum/show...56&postcount=2.

The XL2 has a current limit setting where you can set a limit in amps. Not sure how that interacts with the torque control though.

Interesting, sounds like two dials for the same function, which is usually done to confuse the users :D.

By using a shunt you measure the drop across a know resistor... You don´t need any test and is motor independent.

Even if the ESC has no user modifiable current limit, The esc may have a maximum current limit to protect itself.

Looks like Castle will make two new ESCs, one for 8s and one for 12s. Seems like it will probably be a new (or atleast heavily changed) hardware design.

My hope is rising that we'll get some nice 8s and 12s ESCs in the future, yay!

How do you know that?

35v caps? can't be right :)

just shoot castle an email, they are always helpful and friendly

[Lizard]

ruudxd: I don't know for sure, it just looks like that to me :)

Serum: What do you mean with 35V caps? The XL2 has 35V caps, what's wrong with that?

In the light of 12S
