[Charlie-III]

Hope your ESC issues are now resolved. Please keep us posted in this thread.

I just got off the phone with tekin and they shipped me out a new one, They said that it was not receiving power, not sure why . They said something must have happen when it tried to read the hot link and it just went out , nothing we did wrong it just happened. Again this unit was 1 month out of warrantee and they did send me a new one no charge. 1 feather in their cap.


Thanks

Thats great to hear, sounds like Tekin has some great customer service.
I have two of their FXR's and a couple of motors, and it sounds like if I ever need support they are there for their customers.

I am having the same issue with my rear FXR in an MOA.

My setup is as follows.

Dual FXR sharing one set of power leads.
BEC wired to Power leads feeding the RX
RX is a Futaba R2104GF

There is no issue with the receiver as I have tried the front ESC in both channel 2 and 4 which works fine. I have also tried the rear ESC in both 2 and 4 and only ever get the dim lights. I have not run any software updates recently.

Unfortunately I bought mine second hand. Does any one know if this can be fixed? Or is it just a matter of replacing the ESC?

the dim lights means it has to be recalibrated ....i have one of the fxr's in my mantis that goes in and out like that ....it looses radio contact

LED INDICATOR (S) ERROR DESCRIPTION All LEDs Flashing No Radio Signal, check radio system
LEDs 1,2,3 Flashing Radio signal found but lower than ex-pected, See Radio Calibration Section
LEDs 5,6,7 Flashing Radio signal found but higher than expected, See Radio Calibration Section
LEDs 1,3,5 Flashing Voltage Cutoff set below battery voltage or in hi-temperature thermal shutdown
LEDs ramp up then down ESC is in Pit Tune Mode
LED 4 on briefly, then flashes to one or more other LEDs Normal operation, see Temperature Monitor Section.

Thanks, I have tried to recalibrate it a heap of times and can not get it to go into Calibration mode. I will have a play around with it on the PC via the hotlink to see if that will breath new life into it.

Hey Camo,

Is the FXR decased?

Remove the heatshrink and check it again.

Remember the problem I had with one of the FXR's in Vegas....it was the decased one with the cables re-routed. Dan removed the heatshrink and straightened out the wiring and worked fine...

Likely a short or crimped wire for that one....

Worth a try anyway.

Cheers,
Mike.

Thanks Mike, I ran the hotlink update and that did nothing. SO I went with your suggestion and found the culprit. The receiver wires were shirting at the circuit board. A little dab of CA rubberised glue to keep them separate and she will be good as gold.

Hey Camo,

Sweet. Let us know if it's all working fine now.

Cheers,
Mike.

Not quite there yet. I am still having some dramas. all seems to be working when things are not taped or heat shrunk together, but one every thing is placed onto the skid. it all just seems to go a stray again. The other issue I am now facing is when testing. Is when I throttle and release the rear motor will stop straight away but the front will continue to turn for nearly a full second after release. I gave up last night at 12:40am so I will have another play tonight

Likely a dry joint somewhere and it's getting stressed when covered and mounted. Sounds to me like this unit needs to be put back in it's case and used elsewhere.

There is a setting in the FXR's to do that....can't remember what it is called, but check through the configs of both in HOTWIRE and make sure they are both the same as the REAR.

Cheers,
Mike.

Absolutely what I needed to find! Decased, shrink wrapped, took hours placing an soldering my electronics.. all for no motor.. ugh!

All lights dim, everything working but go power.. found this thread, cut the heat shrink off, BAM, fxr calibrated an all is good!
