Making an esc better?

[zeropointbug]

Yes, I agree that copper is a better conductor than alum., but are you going to mount that Quark to a heatsink? Even then, the heat has to pass through two thermal interfaces, not just one (when in a Quark case), that will be limiting it. If I made my clamp from copper, I would maybe lower the temps by a few degrees. I just wished that I had found a smaller/ligher heatsink for my Quark, as mine is too tall for mounting if lot's of places.

This makes me want to get Mike to make my 'custom quark case' that I designed 6 months ago.

Yeah, nothing is that simple saddly. Although..... **ding, idea**

Wouldnt it be cool if a manufacturer could release a brain board or unit, that could be plugged into different size/rated power boards, so you could easily upgrade your esc to a more powerful unit for less $$$. I like that idea alot....

[zeropointbug]

Yeah, that would be very nice for all of us!

Modular design approach makes a lot of sense in a lot of electronic designs these days, but sadly, very few manufacturers do it.

Actually, I had sorta expressed that desire a while back; a modular type of ESC with a universal brains board, and then the user can pick the power board to match their needs and just plug them together. And while we're at it, might as well also make the power boards stackable.

Stackable for sure!

Wow, back to sensored systems, ... long time no interest and finally.
I'm slowly (for one of my projects) making a power board for HV-Maxx, but was not expecting any interest in that combo here. Feigao has full line of sensored motors and Aveox as well. Well, I had a thread here on HV-Maxx and Feigao combo...

Mamba first, Quark second which brains we want to add?

To zeropointbug:
How much power you think you dumping on ESC?
What kind of Amp ratings you would like to have from ESC and why?

[zeropointbug]

Is this a question about an esc Artur?

Can you elaborate on what you want to know? I just don't know exactly what you are asking.

Ok, step by step:

Related to your ESC-
a. Why you need heatsink at all?
b. How much power you need to dissipate?
c. What temperature range of the ESC and FET's you would like to have?
"How much power you think you dumping on ESC?"

Related to future ESC-
a. What temperature range of the ESC and FET's you would like to have? (copy of "c")
b. How long you would like your ESC to work continuous at 25%/50%/75%/100% load?
"What kind of Amp ratings you would like to have from ESC and why?"

Heatsinks could be a mute point if the capacity of the board/fets are sufficient right? but by weight what weighs less to do the same work, a small board that performs well with a sink and fan- or a large board that does the same work with minimal heat?

Speaking of stackable, is it possible to get a MM powerboard without buying a new ESC, and how many power boards will the brain control befor it's overloaded?

Welcome to RC-Monster!

Castle Creations didn't replay on any of my e-mails, so do not know.

As far how many boards you can stack, 2 boards would be the sweet spot. Then you will create layout troubles and total gate charge of more then 24 FETs will exceed 1.25A driver ratings at 10kHz.

Hmm, talking about MM powerboards made me wonder: What happens to all the 'broken' escs which have just blown a fet or some other minor component? I know alot of people seem to just throw their dead esc in bin since its out of warrenty, but perhaps we should have a recycling program (read that as watch the forums for people who have just killed their esc, and offer to buy it from them for next to nothing- then turn it into a brand new esc even better than it was before)....

I thought that they can be fixed for $50 by Castle...

[suicideneil]

Yeah, thats exactly right. But when I read around sometimes it seems that a few people just toss them in the bin because they think the damage is to bad. I dunno, I could be imagining things again though....

As for sensored motors, looking at the prices of the Aveox motors, they are rather expensive when compared to similar spec Neus, so I may be barking up the wrong tree with my idea there. Still, it would be good to have an esc that doesnt conk out when running the Hv4.5, seeing as its a bit too much for the HvMaxx esc sometimes.

[DrKnow65]

Mabey a sticky for people to donate their dead MM's to science (all be it mad science)?

[suicideneil]

Tee-hee, mad science is the best kind.
