can someone pls ?
 

i need help on how to set up my esc run in series..im new to electrics..i actually posted on the wrong thread about this but i will ask again..
im also curious what caused my esc to burn..i got it used and i connected it as seen on the pix..less than 10sec i heard it sizzle..are my connections right?and do u think it messed up the esc when i used a y-harness to connect it to the rx with the brake servo?

Wiring looks ok. Same as my 9920.

The Y harness wouldn't harm the ESC. Must have been a previous fault before you owned it.

Yes, it's okay, if the plugs fit together like this.

I agree with Darren. This is exactly why i don't buy electronics used....you never know. Even when they seem like a good deal, makes me wonder why they are selling. Anywho, i hope that it's not the esc! good luck.

You might have just toasted the internal BEC. Did you pull the red center wire on the plug that goes from the esc to the RX. This disables the internal BEC. I'm not sure what the cell limit is on the internal BEC for Mtronics, but I know w/ the quark the limit is opnly like 8 cells. With a higher cell count you need to run a rx pack or get an external bec unit.

The rest of the battery wiring looks good. Make sure you dont have some wierd short from a stray sloder blob or something. Other than these 2 things I have no other ideas. Could just be a bumm ESC.

thanks guys..when it sizzled there was a black liquid that came out on the side of the esc casing..so i think thats not just the BEC..so the quark125 can only use 8cells?is that combined or per pack?im gonna be using a total of 12cells of ib3800s is that good?
anyway are feigao nemesis and wanderer both the same?just different labels?

Yea, Feigao, Nemesis, and Wanderer are pretty much the same. I would choose a Feigao C though. The Quark is rated for 10 cells, I think. I would still use a UBEC. It will run cooler.

You can use up to 16 cells on the Quark125, but f you are using more than 8 cells you need to disable the internal BEC by unpluging the red center wire on the plug that goes to the Rx. Theinternal BEC is only designed to take 8 cells max. The rest of the esc can handle 16 cells.

You should use an external BEC anyway. It takes the load off of the ESC and helps keep it cool. http://www.rc-monster.com/proddetail.php?prod=6vubec

Yes, all of theose motors are the same. I like the Feigao with the heat sink fins built right into the can. http://www.rc-monster.com/proddetail...540C_XL&cat=20

My 9920 is wired pretty much the same way. I only used 2 sets of deans to wire mine.You can shorten up your wires by getting rid of the connector on the esc wires. Take that connector out of line and run the esc wires to the male dean that comes off theother sideof the battery connector. Still a Y but not completely removeable. You only need to disconnect one battery plug as this cuts the circuit to the ESC. This will help shorten the wires about 1 1/2in on your setup. Run an UBEC to help take some of the load off of your ESC.

Nice use of the link feature go4gold! :dft012:

(for the confused people: it's a reference to an old thread...)

The Quark is actually rated for 18 cells or 6S LiPo max, and I'm almost positive 10 cells on the internal BEC.

Right as usual squee. I stand corrected. :007: :032:

:010:

:018: .

Black Liquid??? That sounds kind wierd...

Like melted plastic? Did it staty liquid?

It's the resin goo that encases the controller I think... when it goes nuclear it melts the crap out of the pool of resin...

Mine would should out like a torch when it blew... and I think mine was the bec that triggered the meltdown.

I have pics posted in a "Mtroniks" thread somewhere...

so ineed external bec so i can run my 12cells?
what if i run 1 pack of 4200mah 2s2p lipos?will it make a difference versus 12cells of 3800mah packs in series?

and so after i take that center red wire i can just plug my batts or i need to do something else?and will i still need the external bec?or i can put the external bec and leave the red wire connected?

2s2p is only 7.4v so you would need a 4s2p to run like 12 cells (14.4v) (actually you wuold run better on lipo)

You also NEED AN EXTERNAL BEC like a UBEC or RECIVER PACK. you can't just pull out the red wire. (you need it disconected with UBEC).

I would run a bec no matter what. It's a lot cheaper than an esc. Can't help with the lipo ? as I don't know much about them.

BrianG, It only took me 2 tries to get it perfect. One day back from vacation and I'm ready to hijack another thread.

so do i still need the UBEC if i connect the rx hump pack?
connecting the rx pack will solve this?can some one pls show me a pic of the wires?
btw the quark125b can run 5s?so the 4s2p will let me run it without the bec or i still need it?
guys im sorry i got too many questions..:013:

No, you can run one or the other. Ans with the Quark, you can run 5s on it. Just make to remove the red wire and use the rx pack.

can u show me a pic of ur set up pls?

Which part?

here is a pic, the ubec is on the side of my reciever box. You wire it to the battery connectors, the nother that has the plug for the reciever, obviously goes into the receiver.

Ok, bad pic..to small...one sec

this is with my 9920, but is the same as setting up the Qaurk. When using a UBEC or an RX pack, that replaces the bec in the controller. So when you use an rx pack, or the ubec, THEN you pull the red wire.

man is there any easier way?heheh it looks complicated..so i can just connect my hump pack to the rx and take the red wire out and im set?does it matter how many mah is the hump pack?i have 1400mah hump pack is that ok?

hey man thanks for the info and pic ..

Yes, just run your hump pack and pull the red wire. The ubec replaces the hump pack if you wanted to loose some weight and have a smaller package. Either way will work

yea i think thats the easiest way just connect hump pack...
btw i was lookin at these batteries a123 lipo batts they are 4600 2s2p ,can i run one pack for the savage or i actually need two to run it?

2...2S would be like running it on 7 cells...
