Quark fried, blown capacitor...

[Serum]

Yeah, the 125C versions will last longer on higher temperatures.. I am curious what they do..

125C version? You mean a Quark 125C? :032: :eek:
Was there a 125A?

GriffinRU, yeah, I'm trying to think of best way to get as close as possible to Quark with caps, it's hard.

I'll see.

temperature rating..

While I had my Quark, I did mount up a bank to it. If you stick the bank on top of the Quark with the bank leads just over the battery leads on the Quark, you can make the connection with a very short piece of wire. Just watch the orientation of the + and - leads before you encapsulate everything. Ideally, you'd have the corresponding + and - leads on the esc and bank vertical to each other. The distance isn't far at all.

Griffin, I don't know that I have the right stuff. I know that my placement of the caps is only as close as I could get them. I also know that they have had a positive effect, so something good must be happening.

So...fill me in on this inductance. Something more to worry about.:019:

You do the right thing, my post was just a note saying that quality of connection and shortest path is more important here then number of caps and the parameters.
If you want to get a little bit more in-details, then I will recommend to read app. note AN-978, and just read around as well. If you have any questions, send me PM.

Artur,

Thank you for the reference. If you know of any publication along the lines of "Speed Controllers for Dummies" I'd appreciate it if you'd let me know. My obsessive compulsive nature is kicking in now and I NEED to know more.

Printing the app note now. I'll leave it on the top of the toilet where I know I'll read it. LOL

I had I chance to add 4 caps on the MM in my Ofna MBX basher. I don't think the MBX was ever intended to have this much power. It really doesn't handle all that well compared to others, but it makes a great basher. It's set up with 10L, MM, 4s Flight power 3700mah.

I made a 4-pack of caps. Strategically placed them so all the negative wires faced the middle and then ran the positive wires along the out side. Used some tape to hold them in place and shoe goo'd them togeter. Soldier them up and added some shrink tubing.

Maybe its my imagination but the caps seemed to make it punchier. I never had problems with heat at the ESC but the temp was an ice cold 100* with fan attached. I think the ESC is running cooler by about 10-15*. Here are some pics. I can't wait to add caps to my Quark controllers.

Capacitors are my best bud, they always have been. :027:

Crappy weather today and didnt really get to run it much. (rain) I did get a to run it once but I got similar reslts with a thermal after about 5 minutes in the grass. BUT, let me tell you, the grass was tall and thick today so it could have been a big factor in the thermal. I'll tray and get it out again one night this wek and do a little more testing to get a better evaluation. From what I did today I cant really tell much of a difference though.

I used a 5 cap bundle added into the battery wires as close to the esc housing as I could get it. I can say.... I wasnt worse so I dont think it was huting anything.

I'll let you know what I see whe I get a chance to spend a little more time with it and get some more conclusive results.

Well, good to hear that. IMO, the leads are a little long on the caps (cap leads), but it should work decent. anything helps.

Do a good hard bashing, and quickly as possible touch the caps to see how warm they are. I still don't know what exactly I will do for mine. If I know how warm they run, I might just use shrink wrap on them. Seeing as CC uses it on theirs... just IMO, from what I have seen with computer motherboard caps, the MM look like they are better quality caps, and/or better performance. This is just based on the color of the writing, not decisive though.

My caps were not even warm, but it might be different in other applications.

Guy, in my setup, you really have to run it to get to feel the difference in heat. I ran my 8ight today with the MM with the 4 cap bank. After a solid hour of running (I think I toasted a Feigao), I temped 160 on the esc. The funny thing is that sometime during the running, the fan got busted. Oh, and BTW, it was a good 90* out today. In the middle of the day, I took a temp on the tailgate of my truck and it read 110*F. It was hot! I know that my MM used to NEED a fan. Now, it's running 160, without a fan in the heat. I like it.

When I get my Neu motor, if it runs well on the MM, I'm sticking with it. I'll sell off the Quark and Compro.

I think we are seeing the same thing. Cooler temps on the ESC.

Man, I hated the way My MM/Neu stuttered. It was unacceptable to me. Sure will be nice someday though when they get out an update for that.

So you haven't tried running a Neu with your MM yet Cartwheels?

You should try it! :027:
