BBB Beetleweight Dual Brushed ESC
$42.90
Designed and assembled in house by our very own Gareth we’re very excited to make our totally custom beetleweight dual brushed ESCs! – Literally consider this two of our BBB ESCs in one package with built in mixing too! All the specs you need in a brushed ESC – centre braking, safe start, failsafing, current limiting, higher voltage support, built in BEC and of course the signature startup tone! This ESC will happily run four brushed 22mm or 25mm motors! Pairs well with our BBB 22mm Planetary Gearmotors at 3-4S lipo for 2 or 4 wheel drive. LED, mixing, beep & wiring instructions below.
- 4S lipo support – can happily run 4 x 25mm motors at 3S, 6 x 22mm motors at 4S
- Small and lightweight at 10g – can save weight by shortening wires
- Current limiting – high current motors (eg – nerfs) shouldn’t blow up the ESC
- Center braking – brakes motors when the sticks are centered for better control
- Failsafing – no unexpected movement when transmitter is off / loses signal
- Safe start – stick must be centered to arm (short beep/flash until stick is centered)
- Built in mixing – for easy driving, can be disabled, more info below.
- Built in BEC – enough current to power a receiver, use external BEC for servos etc
- 17th May: Adaptive current limiting: 2-3 secs of 10A, 10 secs of ramp down to 4A
- 13th July: Short circuit protection at motor output (see LED indicators below)
Do not use two BECs at a time – more info on this below.

LED indicator light & beeps:
Start up beep = ESC has just powered on – it is receiving power and is connected to motor(s).
Solid LED = Powered on. Receiver ready, ESC is armed.
Flash & beep with short gap = Powered on. Throttle isn’t centred.
Flash & beep with long gap = Powered on. No receiver signal.
Rapid LED flickering on start up = Short circuit detected, disconnect your link immediately and check your wiring.
Driving & Mixing
By default mixing is enabled on this ESC – the servo connectors drive the following:
– CH1 is steering (turning left/right)
– CH2 is drive (forwards/backwards)
These match nicely with the defaults of the FS-i6 transmitter + flysky receiver (CH1: AIL, CH2: ELE)
If your turning or driving is backwards on your transmitter, you’ll want to reverse the appropriate channel above.
If you want to disable mixing, there’s solder pads labelled on the back of the ESC – you want to create a solder bridge between them (and then re-heatshrink the ESC) Each servo connector will control one drive side and you’ll need to set up your own mixing – see our guide.
Do not use more than one BEC at a time – see both diagrams below:
This dual ESC comes with a built in BEC perfect for powering your receiver.
If you’re powering a servo or other higher current components, use an external BEC – unplug the ESC’s red servo wire, we recommend cutting this wire (or taping over the metal connector) to prevent risk of shorting.
Orders before 13th July 2023 during the beta run had a failsafe bug – certain receivers if they’ve disconnected multiple times from the transmitter will cause the ESC to not failsafe properly – if this issue occurs for you please contact us to get a firmware update.
Typical Beetle Wiring Diagram
Please note: We don’t recommend running 25mm motors above 3S, however our 22mm Planetary Gearmotors will run 4S lipos. Typical Beetle Wiring Diagram for two or four wheel drive:
Using ESC’s internal BEC – for powering just a receiver.
Components in this example: 3S or 4S Lipo, Beetle Safety Kit, Breakout cable, BBB dual ESC & as BEC, BBB 22mm Motors, and Flysky Reciever.

Excellent from pretty much every point of view.
I am running 4x 25mm gearboxes with the more current hungry blue endcap motors on 4 cell, grippy rubber wheels and it hasn’t missed a beat yet. Basically the worst case for loading you will realistically have in a beetle and it just chugs along happily so current limiting is working. Braking is great so it feels perfect to drive. Will absolutely buy another for any brushed drive projects.
