Cut off temp Firma 150A

[Kljin]

Does anyone know the cut off temperature for an esc Firma 150A?

 

[Garcbomber]

Max 8 is 221 default, I’d expect similar

 

[Senton_Prime]

I think it's 212.. I can't remember.. why you wanna know, stay far away from that number!!

 

[Kljin]

I mounted the 25T pinion gear recently on my Infraction V2 and I'm seeing temps of 85°C (185° F) on full throttle when I get the cut off.
Was wondering if it's bc of the high temperature or bc of the Amps...

RTFM

 

[Senton_Prime]

LVC, but you running a little hot so maybe address that as well!!

 

[Kljin]

If I install XLX2, would that solve it all?

Drop your timing and punch down the first or 2nd settings, the light will tell you the reason for limp mode.

Betting you don’t have enough quality voltage under full trigger so it pulls down to LVC.

Punch is allready set to 1, timing still stock.
Where would you start with on timing?

0-11*, unless you were at the end of the run you exceeded amp draw. Thermal will stop Fwd/Rev, LVC or amp cut will go limp mode.

212F is the Thermal failsafe cutoff and this is measured Internally by the Thermistor at the Mosfet Power transistors.
Measured Externally at the ESC's Heat sink, with a Temp gun, is usually 160F-170F give or take. When mine does a Thermal Cut, ESC's Led Flashing Green, this is what I read with my temp gun.
This is your guide, with a temp gun in hand. Hopefully you have one, since you are asking this question.
An Important RC tool to have..
You want to prevent Thermal cutting from happening in the first place. ESC fires are a thing, if you ignore this. Also, Proper pinion gearing is key here.

Just back from testing and there are no lights blinkings what so ever on the esc.
It also cut off on the first run, so very low temp of the esc.
After the cut off, i can get immediately back on the throttle

 

[Kljin]

Now I did the test with motor timing on level 1 and punch setting on level 1.
The cut off is still there on full throttle.

Temp of the motor was 50 degrees Celcius, the esc was in the 80s.

 

[SrC]

50c motor equates to 120 F. Thats fine. 80C at the ESC equals 176F. Should thermal cut in theory.. Just You are not getting Any Temp cutoff, if there is No Green light Flashing.
You have another different issue there.
Could be a Brown Out caused by something. BEC related perhaps. Causing Intermttent signal glitching.
If the ESC is flashing Red, its an ESC LVC /lipo power issue.

Now I see a red blinking on the esc…

If i put in an XLX2 esc, would that take care of my problem?

Are you wanting to bash a xlx2.. what vehicle is this, that you have a 25t pinion on.. I'm sure your hitting LVC, how old are you lipos, many factors can play a part

 

[SrC]

25 pinion? What size spur gear?
A Lim or Infr maybe???
Yeah what model are you running????
Need more info.

No, just speedrunning
Infraction V2 6S BLX
Lipos are 1 month old, may 10 runs.

Spur gear is stock, 46T
Infraction V2 6S BLX

Sounds like the ESC is amping out?

 

[SrC]

With the stocker ESC, Amp cutting is a thing. Even crappy lipos will cause this.
Been there with hard speed running. Careful, major carnage can result.
