Arrma fury motor load problem

[Sjenk6350]

Hey yall I got an arrama fury for Christmas just this last year and it ran well for the 5 times I ran it then it started doing this thing were it would run fine then the motor would stop working but the car was still on and could turn I got told maybe the switch between lithium and copper zinc whatever could have been switched but I made sure it was on the right one then I was told the slipper nut was too loose so I tightened it a little at a time and it just kept getting worse so I tried loosening it but it didnt get any better I also pulled the first gear in the transmission off so it was just the motor gear and I tried holding that to see if it was the clutch but the motor still cut out it seems like the motor just cuts out whenever it has a load on it

Welcome to RCTALK.COM!!!

Punctuation would make your story easier to follow. Let me see If I have this right...

Your car ran fine 5 times, no issues.
Then you started having the power issue.

Did the problem happen as soon as you plugged the car in and tried to use or did you run it for a few mins before it cut out?

Have you 100% verified that your batteries are charged fully?

Do you have any flashing lights on the esc when the problem happens?

Did you notice if either the esc or motor were hot when it cut out?
A digital temp gun is super handy for RC. Buy one if you don't have one already.

I am unclear about the changes you made with your gears.
You seized the motor and then tried to power it?

With the motor out, does the truck roll forward and back smoothly? No binding at all?

We need more info to help with the problem...I think. I also have the fury, mine is still mostly stock. It's been a great truck. I have only run it on 2s lipo. Let me know if there is something I can check on it for comparison if you need it.

Sorry I suck with punctuation it did run perfectly for the first few times I ran it went from full battery all the way to dead. My most recent attempt to run the rc car, I pulled it straight off the battery charger and connected it to the rc car, it ran fine for maybe 20 feet then cut out. When it cuts out the ESC does have a very small flashing red light but both the ESC and the motor were only warm not hot at all. I havent made any changes to the gears other than attempting to adjust the slip nut which to my understanding is like the clutch in a car. I wanted to see if it was the motor giving out or something else to do with the gears so I pulled the motor out and held the gear and it cut out immediately, it didnt even hurt my fingers or anything. With the motor out the truck moves perfectly fine.

It really sounds like your battery is dead to me.

I pulled it straight off the charger and the charger said it was full

Check the low voltage jumper on the esc to verify its on nimh and not lipo.

Its on nimh

Try rebinding. Cleaning the motor may work too. Otherwise, you need to buy a meter to start testing things I think.

How would I rebind it?

This one shows recalibration. Try that too.

Nevermind now it wont turn at all

Stupid question did you unplug the battery and plug it back in after recalibrating? Try recalibrating again, unplug and plug in again. You shouldn’t be leaving any battery plugged in after running it. On that and similar ESCs often soldering the switch wires together takes away a failure point.

 

[CertifiedMike]

Ok. So where are you at now?
Recalibration worked?
How long did you run it before it stopped?
What was happening when it stopped?

I would prob start at the beginning of the bind and calibration proceedure if it just cut out again.

Seems odd that your gear seems to not want to stay bound.

Are you sure the transmitter batteries are 100% charged/new too?

Is there any chance this esc got wet while you were running it?

Recalibration did work the motor doesn't cut out now and when i went to drive it it just didnt turn at all I did the recalibration 3 doffrent times yesterday and it never got wet and the battery's in the transmitter are 100%

Turn on transmitter, then you plug the battery in to the car...
Nothing?
No flashing lights on esc? No noise? No servo control at all?

Does the light on the transmitter work?

Its time to invest in a meter.

They aren't very expensive. You could have a bad battery, wiring, solder joint, connector issues... Testing is necessary for answers at this point imo.



Another option is to contact Arrma about warranty. See if they are willing to send you parts until you figure out what is wrong.
