Fried my B1R
 

I have a tekin B1R in My Mrc, I hooked up a team brood Frenzy motor. and it fried my B1R I am sure I had it set up right.
Tekin says the B1R has no motor limit other than it has to be a 350 size motor. Any advice would me great.

Did you let the wire leads touch?

No, anyone run this motor?

Re: Fried my B1R
 

The motor was most likely not the cause of the esc failure.

Do you have a Bec installed?

I've been told that the bec circuitry in a B1r is very sensitive to crawling applications and requires the use of an external one to meet the demands of 2.4 receivers and high servo loads. Otherwise it might fail, sinking the whole ship.

I have heard of that with a B1R, What if I were to run a FXR would I still need a BEC?

I always recomend a BEC. Always. The fxr is a 1/10 esc and thus more robust so it will handle when your truck gets bound up between rocks better. Always run a BEC and always run a cap with the esc. Just my $.02

That being said I've been running a B1R with a castle BEC since January without issue.

X2 on what Happymachinist said.

Yes, I would still recommend using a bec with an fxr, even with it being a 1/10 esc. The B1r is also good, but a bec is definitely a must.

Re: Fried my B1R
 

If the servo is ~200inoz+, then yes, you need an external BEC. The Holmes BR-XL/BR-SL can go a little higher in servo rating before it needs an external BEC.

What battery were you using? I've been using a B1r for about a year and I went and resoldered it last month and when I plugged it back in it started smoking and now it's got a black spot on it and doesn't work... I did take off the wire posts and the case but that shouldn't have affected anything...

Re: Fried my B1R
 

Are you guys using the external capacitor?

If not that would cause certain death of the ESC.

Re: Fried my B1R
 

I have ran without a bec for years, with a hitec robotic servo, I direct wired it. kinda like a bec. with a hand wound 35t motor. yes I have also run the capacitor,
I run a 2 cell thunder power 1350 batt. this all ran great for years but my motor is getting weak and I wanted to try something else. when I wired up the brood motor
the B1R fried. I have gone back to my old 35t motor for the time being, (1.9 comp crawling is still be where I live). I have just wondered what what people thought
about what would have gone wrong. and who has ran the brood frenzy motor. thanks to all that have taking the time to answer this thread. you have been most
helpful.
