Am i using the wrong esc?

[The Doc]

Ok, I'm running a 2200 3s with a fxr esc and a Crawler Master 13t motor. people say this motor is = to a 35 turn and tekin says it will work with a 3s 35t motor and up, but the motor limit is 13t, I'm starting to have a problem with the esc cutting out, meaning that within a 3 to 4 min window if I just run it semi hard and keep turning the wheels back and forth it will die, than it seens if I let go of the steering it will run in about a sec or 2. but not always sometimes it will just set there and than take off. The esc is at about 110F on temp, and that's only after 3 to 4 min and its cold out side. Should I not be running the fxr and should I be running a fxr-pro instead. I'm also running 14 gauge wire, I know alot of you run bigger but I'm not comping anymore and I run this set up in all of my scalers and they work fine. O....this is the lowest motor I have ever run my other ones run 45t and up.

I think what people are saying is it's = to a 35 turn as far as low speed control, it's still a 13t motor.

Per Tekin's site:
Input Voltage: 4-9 Cells, 2S Lipo (3S Lipo with 35T or higher motor)
(also per their site it says the FX R will handle a 12t on 2S)

Time for the stupid question, external BEC?

If you have a 2S available to use try that and see how long it runs, it would be an easy way to know if your over powering it.

No bec at this time but I do have one. I just found a post of a esc shutting down on 3s and not 2s. But like you just said I going to try a 2s first. Do you know anything about temps, is it getting hot to fast? One thing I forgot to say is I running JR Z9100T steering servo

[The Doc]

Ok, just ran a 2s and no prob's. If the tekin cant handle a 3s with this 13t than what esc should I get that will work and have a good drag brake and a immediate reverse. I need a foot print if possible close to the same size as the fxr to run in my water proof box. If I do run a bec that's not going to help stop the esc from getting hot so fast would it?

[ThunderVP]

The esc should be fine running the motor on 3s if its only at 110°, but what's most likely happening is the ESC internal BEC is shutting down running the 3S with a high torque servo. Using an external BEC will keep that from happening.

+1 I had thermal shut down problems from an internal bec just last week.

[JohnRobHolmes]

Sounds like an internal BEC issue. Put on an external and see how it goes.

The FXR is totally fine with a 13t CrawlMaster.

[The Doc]

Thanks for the reply's I'm going to put on the bec. The only question I have now is castle talks about having air flow over the bec, if I seal it up from water will in get too hot.

Seal it up, you'll be fine. I've never had a sealed up BEC overheat.

just get a HH BR-XL esc, no need for an external BEC, they come waterproof, and can handle any brushed motor!

Thanks, War Pig

Is the BR-XL much better than using the FXR with a bec, the BR-XL is water resistant but should you pay for the extra epoxy job? I did take the FXR out of one of my other scalers (couldn't wait to get the wraith going) so I could put it back.

John, are these in stock and could you ship Monday if I decide to get one.
I know your out of town but just incase you check this post.

Thanks
