Esc questions

[Welderman85]

Hello all. I'm almost done with my build but have no idea what to do about a esc. The truck has a brushed motor currently. I have a few old esc but I was wondering if i should up grade to something with a drag brake.

What are you building? If you stick with the brushed motor go with the HW1080. But a little more info on what you want would be helpful in making recommendations.

Sorry I was way to tired when I post this. It is a tamiya cr01 I bought used and changed a bunch of stuff on it to hopefully work better. It will be a mostly trail truck with some crawling mixed in. It currently has brushed but one day would like maybe upgrade it to brushless.

It also has 4 wheel steering so dual servos if that makes a difference and I mostly run 2s packs. Running two servos will I need a BEC. The servos are power HD 20kg sorry I'm new to all this. Thank you

Yes to drag brake, Hobbywing 1080WP is probably the #1 option and hobbywing 1060 at #2

Yes to the bec, always run a bec unless you're using a Castle Mamba X (it has 8A internal bec)


Sorry for my point form reply but sentences are tiring..

Also recommend HW 1080. You are probably ok running those servos without an external BEC on a 1080. I'd see how it works before deciding if you need an external BEC.

What Bec is a decent one or all the same. Am I wasting time with a brushed esc. Should I just go brush less.

HW 1080 for the ESC and a good rule of thumb is if your servo is over 300oz of torque, use a BEC. Using a BEC (relativley cheap) helps take a load off of your ESC (sometimes cheap sometimes not).

I use Castle BECs and never had a problem with them, about $20

The servos are dual power HD 20kgs . I order the hw 1080 but is the castle 10 amp the correct bec. Thank you for all the help

Not wasting your time at all. Brushed motors are great in crawler and trail trucks.

Except my personal policy is that if the servo is over 150ozin of torque I run a bec. I've had more low torque servos brown out than high torque.

Yes, Castle 10Amp is a great bec. You could also go with the newer/more expensive/waterproof one, but it's a lot more money and the only functional gain is the fact that it's factory waterproofed.
