The Q Brain provides the perfect power solution for your quadcopter by incorporating 4 x 20A 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.
Tom, the DT750 has a max 18A draw. The Qbrain would work. The QBrain would cost a little less. However, four indvidual 20A escs would also save 10-20g (20a Blue series - 18 grams* Multistar - 25 grams). I'm also in the research stage of developing a quad....cheers
I got mine a couple of days ago and installed it on a custom 500mm quad. Before getting into that let me say that I am very pleased with it. The quality of workmanship and overall appearance is excellent. My first thought when I took it out of the packaging was that is was heavier than I expected. After weighing it however I found that it was almost exactly the same weight, including the installed 3.5mm bullet connectors, as the four Blue Series 20A ESCs it replaced. The wire length was greater than I needed, so by cutting them down I could get the weight down but decided not to do that. I was at a loss about how to install the Q Brain on my quad because there are no mounting holes. I wanted it mounted securely so elected to remove the back of the case and attach it to the deck using nylon screws to avoid the possibility of an electrical short. I then re-attached the case to the back plate using the orig screws. Note that doing this might void your warranty. My quad has 16mm carbon tubes for the arms so I was able to route the ESC wires through the tubes to the motors. Installation was much easier than using individual ESCs. On finishing it I was struck by how clean and neat everything looked with no exposed wires. I have completed several successful flights with the quad and everything worked perfectly. Throttle and control response is very smooth and fast. I h

It appears Kaptondave is a lying POS! In his review on 8/19/2013 he clearly states how pleased he is & how clean the build looks & even says he has "several successful flights"!
On 9/22/2013 CarbonComposite writes Kaptondave & tells him he likes his review & politely asks him if he has video or pics of his quad & as surprising as it seems Kaptondave writes back on 9/22/2013 (later that evening) an clearly states he can't provide photos because (QUOTE) Have not built it yet! (End Quote)!
It really disgusts me that folks blatantly lie like this & sad too, because initially I thought , "cool" this is a good product but then you catch them in their lies & you don't know what to believe. Do us all a favor "Kaptondave" & keep your reviews to yourself! Nobody respects the opinion of a lying POS!
If your quad can use this, I don't see any reason it shouldn't have it. Saves a decent mount of weight, and great to be able to program all 4 ESC's at the same time.

Ordered two of these for some quad builds I was doing. Very good esc's for the price. They work great! Using them with the 2728 1000kv motors on a few builds and no issues! It makes wiring very easy and clean. I will be ordering more!
