BBB Beetleweight 4S 8A Brushed ESC

(7 customer reviews)


20th October: More stock on the way, in the meantime we have a limited run smaller more powerful 4S 13A ESCs!
Originally a brushless speed controller which has been flashed to brushed with MegaBrush firmware with added BBB tweaks – including center braking and a happy start up tone! Each ESC will run two brushed 22mm or 25mm motors per ESC per drive side (these are single not dual ESCs). It has been set up to pair well with our BBB 22mm Planetary Gearmotors at up to 4S lipo – two of these ESCs will work well for 2 or 4 wheel drive.

  • 4S lipo support and up to two 22mm/25mm motors per ESC
  • Lightweight at 7.5g
  • Center braking – motors brought to a central stop quickly.
  • Programmable transmitter Min and Max values (see below)
  • Failsafing when transmitter is off
  • Safe start –  stick must be centered to arm ESC (quiet fast beep until stick is centered)

Also a great option for brushed weapons such as 37mm motors for lifters/axes/grabbers.

Wiring & Programming Min/Max

Typical Beetle Wiring Diagram using these ESCs for two or four wheel drive:

Components in this example: 3S or 4S Lipo, Beetle Safety KitBBB 4S 8A ESCsBBB 22mm MotorsBEC and Flysky Reciever. Image made by Team DSC.

Please note: these are single ESCs and you will need one per drive side of your robot. You’ll need to set up mixing on your transmitter – Mixing Guide. We don’t recommend running 25mm motors above 3S, however our 22mm Planetary Gearmotors will run 4S lipos.

Programming RC Min and Max values:

  1. Power on the ESC, holding transmitter stick at maximum value
  2. The motor will make 3 beeps indicating you’re in programming mode
  3. After 2 seconds you will hear 1 beep, move the transmitter stick to minimum value
  4. After 2 seconds you will hear 3 beeps indicating you’ve reprogrammed the min/max values.
    Note: Mixing may affect these values – you may want to program these values with mixing off.

    you need to invest in these they have survived much abuse

    I’m very new to the beetleweight scene but after dealing with VEX29s for my first build these things are a godsend. Light and simple to use and come pre-wired without needing to worry about chopping and changing. I’ve not exploded one yet (fingers crossed) but can honestly say these are great.

  3. Jon-Luke Buckley (Igor) (verified owner)

    These are the ESCs I’m now using in Igor, and quite happily drive 2 of the 22mm motors each. I’ve had no problems so far, would highly recommend to any beetle builder.

  4. Chris Thompson (verified owner)

    Using these in my first beatle. Very quick and easy to set up and the start up tune is usefull for indicating everything is working well.

    Will end up getting another when the time comes to set up a weapons system using a motor rather than servo

    Have not set fire 10/10.

  6. Reira Granger (verified owner)

    Worked beautifully at Rapture in Metis, work nicely on 4S and withstand some real punishment. Reliable, easy to use and set up, and great value. Highly recommend!

    Although one spontaneously combusted with inch tall flames I trust that that was a one time thing and that it wasn’t their fault, and when I asked if they could replace it they quickly sent two more. The rest worked well for all my fights.
