Overview

The Q Brain provides the perfect power solution for your quadcopter by incorporating 4 x 25A ESCs into one single unit. This keeps the wiring very tidy and allows you to mount this unit in the middle of the frame instead of having to mount an ESC on each arm.

With adjustable low-voltage protection, startup mode and motor timing, the Q Brain is not short on programming features. This and its ability to operate on 2~4S lipoly or 5~12 cells Ni-XX makes it a very versatile ESC.

The Q Brain keeps things simple by having all of the motor leads pre-installed and terminated with 3.5mm bullet connectors. There are 4 x signal leads (one with power) that will plug directly into your flight controller's ESC output ports. A throttle hub is also included for use in applications requiring the use of a shared throttle signal.

Well, Item arrived fast dimensions was not really correct. I'm glad its smaller then given dimensions:

Height:133mm
With: 560mm not including capacitors: with them 693mm
Length: 630mm

that black top with logo actually is a heat sink I'd recommend it gets allot of air.
Well quality isn't top notch, soldering points of 4 wires going to motor was cold join't.
battery lead had overflow solder cap that was touching metal heat sink good thing i didn't power it up! take few minutes to inspect before first start! flying quality is good easy calibration soft start responsive for my uses. does get a bit hot or warm depends how you call it after 15min of flying esc was 55c. oh and by the way it does not fit in x525 or x666 quad frame if you want to sandwich it with quad arm's had to cut square tubes 1cm and re drill the holes so middle is bit bigger after that modification it fits and wires can be rauted trough tubes.

for sure will but again ;)

Had this on a 450 quad before installing it in an S500 where its been ever since. No problems at all with cooling gliches etc. I'm about to order another to flash bellheli on it.

Terry, it is common for this type of component to come without a connector, as there are so many out there, and the end user can simply solder on the connector of his/her choice. Far more versatile this way.

I've added an XT60, as that's what all my batteries are (I started with a Nova), and just spun up my Quanum XJ470 with this board, and it seems to work great! After a few minutes of the maiden flight, she wasn't even all that warm, but we'll see what changes when I start flying with a payload (camera, etc.)

Perfect solution to making a clean looking well balanced quad. No need for power distribution board. Have really pushed these q brains and they are awesome. Using 4 1000kv motors with 10x45 props no real heat build up at all if air can circulate around them. Give them room to breath and you shouldn't have problems. Motor setup is a little confusing for some flight controllers but easy to configure. May have to extend wires for bigger frames ie 600 size plus. Once installed on frame and configured with flight controller you should never have to worry again. Used these on a 450 qaud and 600 quad with extended wires. Have never let me down with over 40 hours use on each. Wish I could say the same for the batteries I bought at same time. Just to sum up clean set up and decent 2200 mah 30c battery 1000kv motors 10x45 props. 10 minutes of solid flying time. What more do you need besides more batteries lol

a bit bulky, i was saving it for a larger build but went with a cheaper plastic frame and larger motors and it flew nice.

Works for Tricopters too. Only slight niggle was that two motor leads were 35mm too short, but made up short extensions and all appears OK. The BEC system works fine and gives a perfectly normal 5.25v but this appears to be enough to destroy small digital servos, so if you are using it for a Tricopter, use analogue servos. Other than that this is a neat and economical unit for a small multirotor

I really like this ESC. It simplifies everything and fits nicely. I'm running a pair of them in an X8 with a simple power splitter cable between them.
