UBEC wires melted with 4S Lipos
 

Guys, I just ran my 4S setup and my UBEC wires melted, I thought it was a fluke, re-wired and it ran slow after a full charge an the same thing happened again. My setup is MMax with feigao 7xl motor, I ran my UBEC input wires straight from the 14V Lipos and the neg wire keeps frying. anyone see this B4?:035:

Welcome to the forums ;

That is odd, why not try putting the UBEC positive to the esc positive and UBEC negative to the the esc negative.

It may be that when you hook the batts up.
You are touching the red wire first. That would let the ubec be the ground.
I can't tell much by photo. Wires are everywhere.

Welcome to the forum though.

Thanks Sylvester, I think that's what I've done, the UBEC pos and neg are soldered to the battery pack pos and neg and they are connected to the ESC input Pos and neg, I'll try soldering them straight to the ESC input wires in case I have a bad connection, but somethings drawing way to much current, check our my neg wire.

That doesnt look too good. Try just connecting them to the esc main wires and try again. BTW, what UBEC is that? If that isnt working too well maybe try the one mike sells.

Believe it or not it doesn't say who makes it, a friend gave it to me, it just says 3A switch mode UBEC, I can't read the japanese, it still works though.

Well, if the problem persists, Id try a UBEC off mike, it should work flawlessly.

have you got rid of the red wire in the rx wire to the rx off the mm.

Yeah, I cut the red wire from the ESC to the receiver.

Hah, told you leroy.. Anyway, try mikes UBEC..

never hurts to ask dom. :D

hey, thats how we learn, leroy!

Are you wiring the bec to the esc??? You want to go from the bec to the reciever battery input. You don't have to power the esc, it will power itself without the bec.
