TorqueMaster BR Mini Packs the Power!

What voltage is your BEC? I had a mt4 receiver go up in smoke with bec connected to channel 4. Rewired my servo direct to be. No more problems

[richard2744]

My bec voltage is 7.4 I have been running it at that for a while using FXR esc's with out problems. Just can't stop the BR minis heating up. Will have to source some ZD's to try the method as per the earlier posts

I tried to send you a PM but could not.

John, any input on my question I asked the other day?

I have my Berg V3 wired up. I am using a Futaba 4PL with a 4 channel receiver. Radio have been set up for Dual ESC. I am also running the new stacked mini BRXL dual ESC. I am also using HH Crawl Master for front and rear motors.

Servo is plug in channel 1, ESC on channel 2 and 3 with middle wire pulled off the plug. BEC on channel 4. I am able to turn my steering but not able to get power to the front and rear motor. Any suggestions?

Ok guys and gals running these, I have these as well smashed I'm my 2.2 pro and I'm still having the motor cut out issue, I've tried reducing the voltage cut out even turning it off, running the bec set to 7.4-6.0-6.5, and I've even swapped motors from my brood vapors to brood appocolypse 35t and still having the motor cut out issue.
My servo is being powered off the bec, I have contacted john and tried everything he has suggested but nothing is working, so I was just wanting to find out what you guys have done to get rid of this issue, also my escs are using the latest firmware 11.1.

How hot are they getting?... When I first ran my br-minis I'd always check temperature after every course the hottest temp my esc's reached. Was a little over 140° (no ZD mod) I have 3 comps & a few practice days w/o failure to date, (After each course they feel warm )
I also have smashed Castle creation mamba micro pro esc's, if I run them hard they'll also reach temps in the 140° range.

My br-minis are smashed normal/common way, cc bec runs servo only esc's power the receiver.

On my receiver 4pl radio my rear motor/esc is on CH 4 & my esc's power the receiver works perfectly.. try switching your 3 & 4 wires.

IMO the best way would be ESC'S CH 3 & 4 leaving both red wires in(this will power the receiver). Wire your BEC +/- to servo's +/- , receiver CH 1 would only have a single wire from servo.

My pair are getting up to the 160+ mark with the diode mod but it does take much longer to get there then before.
I will be changing the motor leads to a bigger size and see how that goes. Currently I run 1mm cable I will go to 2.5mm hope this will wick away some of the heat (sorry couldn't find a imperial size conversion )
I'll post a reply here if it works

Hello everybody.
Received my pair of minis and updated the firmware to 1.11 without any issues. After that the both connection status indicators are green and reading the settings (shift + F7) is also working, but i can not update the settings (F7). Getting "error communication with the device" ervery time.
Any hints or suggestions?
Thanks
Castle Link Version 3.56.17

Edit:
tried the second one using firmware version as shipped (1.10): changing the cut off voltage works. Updated to firmware 1.11 and writing to the device isn't possible any more

Edit 2:
flashed both esc a second time with v1.11. Same procedure as first time, no errors, now writing to the esc works

How do I calibrate these to my transmitter? The only info I found is for the single mini (actually it's for the TorqueMaster BR-XL). It says:

"3.1 Calibrating the ESC to YOUR transmitter
Note: When running two ESCs, they CANNOT have the battery power wires connected during
calibration or programming. It will cause problems with the second ESC.

I've got a pair of stacked minis with only one set of battery leads. Can I calibrate these one by one? Remove one from the receiver at a time?

Thanks in advance.

[winnerone23]

Yep, just calibrate one at a time.

Ran My BR Mini's today in my XR at a comp and they performed flawlessly... It was really wet and they got in water a few times but with the conformal coating on them they didn't cut out at all

Thanks.

I'm going to be in the same boat when I go to calibrate my pre-smushed dual minis. Do I have to cut open the clear shrink wrap and remove power from on at a time?

Thanks

The knowledge you seek is just a scroll up.

[Quiel]

There's got to be a better way than taking the conformal coating off, take both minis apart and rewire just to calibrate both ESC.

You know those little plugs you put into the receiver? Only plug one in, program, pull that one out and plug second one in, program. Now plug both back in receiver and enjoy. Clear enough now?

Ah, that is easy enough. Thanks

What does blinking green lights on the ESC mean?

[winnerone23]

Neutral from the tx?
