HeyOk No Brainer BEC Review

You modified your crawler with a high-torque servo, aluminum rims, sticky tires, brushless motor and controller … and it performs worse. What?! You’ve spent all of this money and got all of the good stuff and now it’s not working right. How can this be? When this happens–and it happens a lot–some asking around will lead to the topic of a BEC or Battery Eliminator Circuit. Yes, your speed control has a built-in BEC, but most are not up to the task of keeping up with the demands of a modified crawler. Those high-torque servos turning heavy rims with tires that are grabbing the rocks all work together to draw a lot of juice, and when more power is needed than is being provided by a stock BEC, things go haywire. The answer is an aftermarket BEC. There are a few options, but a popular one is Castle Creations’ CC BEC. The device gets soldered into your main power source and the speed control receiver plug needs the power lead removed. Not that big of a deal, but not exactly instant gratification or the quick fix of a troubled crawler. And, while wiring in a BEC isn’t all that complicated, many people may not be interested in taking on some soldering and wiring. This is where the HeyOk No Brainer BEC comes in. The No Brainer BEC, unlike the Castle Creations unit, is plug and play. We liked the idea, so we put it to the test.


  • Price: $25
  • Amps: 5 amps
  • Output: 5.5V

The No Brainer BEC is a small shrink-wrapped circuit board with two wire groups. One set of wires leads to a block of Deans Ultra Plugs that allow you BEC to be plugged in between the battery’s female output connector and the speed control’s input connectors. The second set of wires splits into a Y. The steering servo plugs into the Y-connector and the other lead of the Y plugs into the receiver. That’s all there is to it. You just need to plug it all together.

The standard output of the No Brainer BEC is 5.5V, but I ordered our test sample with a 6V output. HeyOk can build a No Brainer BEC to specific requests.

The beauty and purpose of the No Brainer BEC is that there isn’t much to talk about when it comes to the install. I chose to use it in my Axial SCX10 Dingo, and I was literally ready to go in a matter of a few minutes. I opened the receiver box, tucked in the BEC circuit board (it fit with room to spare), ran the wires out, plugged the connectors together–install done!

I was happy to see that HeyOk got the wires length right. Unlike a comp crawler, where electronics are little more likely to be bunched together, everything is spread out on my SCX10. Since I run a lightweight LiPo, it still sits in the stock position out back (for now), the steering servo is still on the front axle and the speed control and receiver are in the stock location forward of the transmission. The point is the wires are plenty long enough to work on the typical scaler.

Using the No Brainer BEC is pretty simply. I had one end plugged into the wires leading to the speed controller, so to use the BEC, I plugged the battery into the small block of Deans Ultra Plugs. This immediately sends power to the steering servo–even if the speed control if off. Once I flipped the on/off switch, the rest of the electronics powered up.

The fact that the steering servo is powered whenever the No Brainer BEC is plugged in (regardless if the speed control is on or off) may be the only potential downside of the No Brainer BEC. It may be a non-issue for most users of the product. It is just essentially to remember to unplug the battery from the BEC.

I have now run the No Brainer BEC for a few months and I am happy to report that I have experienced zero electronics issues. In my experience, a crawler without a BEC is essentially a problem waiting to happen. The HeyOk No Brainer BEC prevents frustrating problems from taking place and it does it the easiest way possible. It isn’t really intended or recommended for the hardcore comp types, but it’s perfect for someone looking for a quick and easy fix that works.

  1. I really like no brainer type stuff, but can I ask…what is this BEC programmed at volt wise? I got Castle Creations BECs and had to program them at 6 volts…6 bolts is what I was told to be a good voltage.

      1. I like your review but have to disagree with you….I believe it’s just as good for comp as a Castle BEC. It’s a little bulkier but it can be turned up to any voltage (up to 20v) with just a turn of the crew that’s on the side. As long as you know how to read a voltmeter. You don’t need to order one specifically to you needs…that always takes longer. Just buy one from RPP or one of the other stores that carry Al Jackson stuff. I put one on a stock Tactic 151oz servo…gave it one full turn to “up” the voltage a little and it really came alive. I also run a No-Brainer on my TTC Truck. Again, turned-up…and connected to Hi-tech’s new HO servo that makes more than 600oz of torque. Obviously a 1.9 trail/comp truck has more room under the body than a 2.2 comp rig.

  2. Cool! I like the Deans plugs and the idea of not having to solder too! I like to solder, I’m just not that great at it.

  3. Thank you for posting your review about the No Brainer BEC!

    I just want to add that on special request, I can build up the product with a multi-turn control for adjusting the voltage. This way, if you are starting out with a regular servo that runs on 6 volts and think that later you might upgrade to a higher voltage servo, you can adjust it to the voltage you would like.

  4. I was a little skeptical at first to order, but found out it was my cheapest option to get what I needed.
    I send an email to Al when I saw that I had a little mistake on the delivery address,and got quick response. (easy fix)

    I explained a bit what the plan was and he customized the electronics I needed.

    The quality seems good
    The service is top notch.

    I hope Al continues to develop its smart and simple solutions
