SV2 problems on moa

[It usually runs fine]

I have a redcat rs10 and am having issues with it since i installed a castle creations sv2 esc. Some specs on my rig are: sv2 esc, flysky 2.4ghz radio system, CC 10amp bec, rs10 axles with 380 series banebot motors and 8 tooth pinions f/r, rovers with 4 ounces per front wheel, zero in rear. hitech 645 servo. 3800mah 7.2v battery or 1500mah 7.2 cbp.com saddle packs. Anyways problem numer 1 is: The clodstall has gotten noticeably worse since the sv2. Ii runs top notch at half throttle and less, but if I stab it or get in a bind and require alot of power it cuts out and comes back randomly until I reduce the power demand. I used the same gauge wire on the motors as on the esc. I wired it like this.
.red + from esc to rear motor -
.black - from esc to rear motor+
spliced red + from esc to front motor +
spliced black - from esc to front motor -
I am going to pick up some deans ultra connectors when I get off in the morning and am hoping my problem is that I am trying to draw too many amps through my crappy tamiya plug.

Problem number 2: I have programmed my sv2 through castle link and I set my drag brake to 213% which is the highest option and my crawler is acting like it has a 15 or 20% drag brake. What is causing this, my first guess was my little 380 motors, but they help like champs on my old stock esc so I don't think that is it. I have adjusted my throttle trim and everything and cannot get it sorted out.
Help needed please, and thanks in advance.

For problem 1
Rewire that thing and use the white as your ground to the motors, there was a firmware issue or something that requires this even though the manual say use black.

I think problem 2 is related to 1

[sabohead]

Well.... I just installed 2 on my crawler. 1st off I am not sure if this is good for dual motors on one sv2? I may be wrong here. I don't think it is the Tamiya con. but I would HIGHLY REC. changing those to the deans like you said. Try taking and unplug one of the motors and see if it still does it. I would start there.

If he has the latest software update he just needs to disregard the white wire.

yea I shoulda mentioned that. the newest castle link update fixes the white wire/ red wire issue with the firmware and I've done the update so somethig else is the matter.

Wait, the Sidewinder V2 can run dual motors?

I thought sidewinders could only handle 1 motor?

It's advertised as a single motor brushless esc, but there are a good bit of people running them on moa's as well as the old sidewinders. Mine worked flawlessly for a few days, it hauled balls and had tons of torque, then it just started cutting out, I called castle and they recommended ditching the tamiya plug.

A "single ESC" CAN'T run a MOA UNLESS you do some sort of switching. Whether it be an electronic dig or servo dig, you need other bits in there.

I'm assuming (here we go) that by "single ESC" I am discounting ESC's like the M2 which is really 2 ESC's in a single package.

As to Tamiya plugs....they can work in a "high amp draw" scenario for a bit, but then they fail.

Go to Deans or Sermos/Anserson powerpoles, etc. This removes one possible issue.

Kinda my point.

I didnt see a Punk or a wantasummit switch mentioned in the list...

and base on the OP, I think he is running dual 380 cans off one SV2?


Therefore frying the ESC and glitching the motors?

[It usually runs fine]

I am almost positive that a single motor esc is capable of running two motors in series or parallel becuase I have read many build threads where it has been done in boats, moa's and race cars, so I don't think my esc is fried from this. Since I spliced off the original power wires there is no way the esc can tell that I am running dual motors, all it knows is that it is sending voltage out of the original two wires. Hopefully somebodythat has run duals off a single will chime in. No offense to the people who replied because I am grateful you took time to try and help me and I am not trying to be a know it all, but I am confident in my research and think it will work without a dig switch. KEEP THE REPLIES COMING GUYS.

OK, let me put it a different way.
Within limits (determined by the wind count of the motors & the ESC limits), YES, you can run 2 motors off a single ESC.

But........you WILL NOT have independent control of the front & rear motors. This means you can go forward or reverse, but both axles will do it together. You are giving up an important part we have been trying to explain which is "dig". This allows "locking" one axle or the other for tighter turning or certain moves needed in a comp.

So, if you don't care about dig, just run a single ESC and no dig.

Yes, the ESC knows, it looks at the amps being pulled. If running 2 ~55T motors you are likely fine, if running 2 ~27T motors, you may overload the ESC.

hi guys...
I was trying to test my new rig with SV2, but the SV2 was not working.
I have 3s lipo, and have CCBEC set for 6.2v.
but, when I plug in everything to receiver, and power on!!
the SV2 didn't doing anything, and the lights from SV2 are all flashing,
if it do a right way, then there is only light will be on is orange, am I right?
by the way,
I did re-program the SV2 after I got this problem, and re-solder it with CCBEC as well. but still have same issue now

Can u guys help me??

thanks a lot

[Charlie-III]

David, does the BEC feed the RX or is it direct to the steering servo?

Did you calibrate the ESC to the radio?

[BEELZEBOB]

I dont think he wired it wrong @ this point, but the motors make me courious.

I cant recall ever seeing a 35t or 45t 380 can.

[david_387]

the BEC is wire with ESC to the deans plug actually.yes, I did bind it with radio.
I tried it again few mins ago. and right now the SV2 became to normal and no issue except motor.
motor is not working when I press throttle, I tried two different motors, but still same now.
and the lights from SV2 are all in correct condition, but I don't know why the motor is not running.

OMG....have to solve this issue otherwise I cannot go to scale comp..no way....lol

I am running itengy 35t motor with SV2.

Ugh, my mistake, I meant, "does the BEC feed the RX or is it direct to the steering servo?"

[david_387]

the BEC is feed the RX, that is what I did for my other rig.
I have same set up and SV2 on my other C2 rig.
but, I don't know why I go this issue now, well, the biggest problem is from motor or SV2??
