The HobbyKing Red Brick ESCs wont win first place for style, though they will take top points for simplicity and reliability. With a basic set of programming features these ESCs are a perfect solution for anyone looking for a basic yet robust speed controller.
Specs. Max Amps: 30A Ubec: 5v / 2A Cells: 2~3s Lipoly Size: 52mm x 14mm x 25mm Weight: 22g (Inc Wires)
Have been using 2 of these for the past few weeks... they held up ok running 2s battery and running less than 18a.....
re-powered both models this weekend... one on 2s * 24A the other was running 3s * 20A both failed on the first flight....
the 2s model had been thoroughly tested on the bench... went to spin up prop ready to launch.... motor spins up... magic smoke released from red BRICK... lucky not in the air yet
3s model had been tested on bench although not as intensively. Bit warm with no airflow.... motor cuts out 1 1/2 mins into flight... luckily ubec still functioning... dead stick landing... red BRICK too hot to touch.... retested when home, motor still only draws 20a amps but ESC is overheating and will shut down.......
These are terrible... horrible start up and obviously not capable of running at their rated capacity
The first thing you MUST do when you buy these ESC's is to correct a serious design fault. And this is a MUST if you want them to live. You have to cut the red foil and then insulate the wire connections (welding) from the aluminium heatsink. (and maybe cut about 2 mm from the AMTEL side heatsink). When you strap these ESC's to the arms of the multicopter ,if you squeeze them with whatever you attach them, the heatsink tends to short circuit eighter the motor wires (and burns your FETs) or the other side and burns your D/A converters... it happened to me before I learned my lesson. Otherwise, there are good and probably robust ESCs.
I ordered 4 of these for my Quad hoping to be able to flash them with SimonK FW. I had all things together like Leocopter has written below. I´*ve flashed several other ESC´*s already - mostly without problems - thanks to kkmulticopterflashtool. In this case kkmulticopterflashtool (v 0.77 beta3) cold not flash at all.
Investigating the matter I fond out that my RedBrick´*s uses the AtMega 88 instead of the AtMega 8. The rest of the board looks exactly the same as linked in the spreadsheet "ESC specs for Simonk".
Has anyone got the same problem or know any workaround ?
Would the SimonK FW fit to the AtMega 88 too ? I also used eXtremeBurnerAVR 13B wich was able to read the AtMega 88 and maybe even to write, but I dont whant destroy my ESC´*s ...
Maybe someone has an Idea ?
Yes same for me. One person kindly offer to flash my ESC with SimonK FW. But it is not compliant with the AlMega 88 (the registers are not he same size). Simon K is planing to update the firmware. But no delivery date. So wait and don't try to flash them.
That's a problem when the manufacturer (or the re-brander) changes his design with no mention of the change or version control ... The original Red Bricks had Atmega8 ...

I've used two of these in my CL-415 Canadair driving turnigy L2210-1650 motors. These are a perfect match for the Canadair. Huge power for take offs, low current for cruising around. I've plugged these into a Y plug so both are powering the rx with no problems. Very highly recommended. Flying on 1 2200-3s 20c turnigy lipo.

Calibration should be set 1. UP the throttle stick to maximum 2. connect the battery to esc 3. beep.beep.beep~ (2seconds to throttle down to a minimum) 4. Complete the calibration set

I use these on quad copter and these has worked well. Just make sure to download the right manual under the files tab.
