The BRXL would be a good bet, but on such a heavy rig the internal BEC will probably not keep up with the servo demand. Quote:

John, I'm thinking of rebuilding my 2.2 Axial with a BWD SSS-R chassis with no dig, my FX-R and a 7T Puller. I've been running Thunder Power 3s packs for the past two years and really like the power. I understand that the 7T can overheat on 3s, but with a light set up and more of a finesse, only nail it when needed driving style, would it still be prone to substantial overheating? I run stock 14/87 gearing as well. I briefly had a 10T on 3s but found something lacking in the overall feel. |

If you are careful on the throttle the 7t on 3s will certainly work well. I would suggest using a 12t pinion.

I have 10t arms here, and am getting another round of 14t arms made right now. Still working on the replacement motors too, they are just taking some serious time.

John, I'm running your BR-XL and a 10t puller. It runs fine on 3s, but I would prefer to run it on 4s (suitably geared down and not abused). I suspect this scenario would be okay as long as I watch the motor temp, but if I get voted into the TTC event at Nationals this year, I would like to run 6s for events such as the mud bog and the truck pull. Do you think this combo will be okay for short durations or should I just stick with 4s.....or even 3s for all events? This is in my 2.2 scaler which weighs about 10.5 lbs. Thanks! Tommy |

I would recommend 4s max for the 10t arm. But for a short time you may have luck with 5s. 6s will beat it hard, so if you are willing to tear it down then you may give it a shot.

Thanks for the quick reply, John. I think I'll just stick with 4s in that case. |

Hey John I was planning on picking up one of the puller combos on your site, and saw that 3s is recommended for the 7t. Would 2s be not enough?

| John, what kind of max temps would be considered "safe" for this 10t puller on 4s? Mine is running pretty warm (often too hot to the touch) and I want to make sure it's not getting excessively hot from the added voltage. |

We recommend 160f max measured on the can. The windings can take 200c, the magnets can take 200c. My only concern would be the commutator above 150c. Running the motor hotter than 160f is no problem, it is just our good life recommendation.

What is the proper way to oil the bearings in a Puller? I've tried a whole lot of different oils but every other time the motor (don't know the word here) starts sparking and running bad until I clean the motor out.

John, do you have any 14t pullers in stock that could be shipped Next Day or possible 2nd Day Air? I would need it by Tuesday or at the latest, Wednesday. Thanks! |

Looks like I missed the boat on this one, unless I hit it via email. Email is always the best way for emergency shipments. | |

WD40 isn't a lubricant, it has more solvents than oil. Sewing machine oil would be better.

This might be more general but is it just speed that causes heat in these motors? I am running a 10t on 3s in a scx10 and mine got pretty warm just crawling around. Does using the drag break add heat? Thanks
