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: 50A Ubec: Nil Cells: 2~7s Lipoly Size: 60mm x 14mm 35mm Weight: 40g (Inc Wires)
It might take a day or so to post. I have modified it to eliminate confusion for these speed controllers.
ALSO check out my post on how to modify the usit. They have a defect...

go to the files tab on this page. I have modified the manual. I highlighted the 4S because that's what im running. there are LV units 2-7S. It might take a day to show up on the files page.
In Russia there is a saying:
As the ship you will name so it and will float ..
That's my brick into a brick!
Please help me in the circuitry. Elements circled in red - strongly heated.
Gray - that I desoldering and checked for heat.
Element "S04A" - always heated. - What is this element? ****alldatasheet**** - did not help.

I had LOOSE soldering material rolling around in it (it was 30A red brick), and FET-s burned out with 5 cm FLAME and lot of SMOKE. do yourself a favor REMOVE the heat shrink, check for soldering loose material, re-grease with computer processor heat -paste (use WHITE, silver may lead electricity) and see if the soldering joints (on 12V and on motor output leads) are not shorted because uf the heat sink-s. (use the silicone film which is included in the ESC) then re-shrink and done.
This is a limitation of the on board 7805 regulator it cannot supply enough amps for heavy servo use and FETs, so when BEC reconnected the amps sag and the FETs cannot drive the motor, It will work with lower power systems which is a bit pointless really, oh well we try these things !!
These can be returned to BEC by opening up the heat shrink cover (thereby completely voiding your warranty) and reconnecting the centre red wire. Not sure of amps available but I would think same as none opto BEC at 3 amps, volt out measures at 5.5v. Have tried these on a number of systems and they work perfectly. I would think they are not a true opto circuit as there does not appear to be any optical isolation in the circuit.
OPTO has no BEC for powering the receiver and servos requiring a separate battery pack to power the receiver and servos. Normal would have a BEC to power the flight pack. With either, choosing the proper voltage and amperage to operate the flight pack is crucial.
Hi,
I can`t program the brake. When I go to point 3 of the menu (brake) and when I choose hard or medium brake there is no effect. It always runs without brake.
Can anybody tell my why?
i have bought this esc ,i did't know that i have to use a separate battery input , why people use this esc while we can use reguler ones , what is so special of it ?

well exploded maybe you did something wrong? I own 3 and every one works great i even put one in a boat with no cooling still good what do you want for under 15$?
Why did Hobbyking remove my review? I bought the item and I deserve the right to have my review for others to view. It died hooked up to a watt meter at less than the rated current and voltage. Why would Hobbyking remove reviews?
in your UBEC futaba connector put to receiver (any empty chanel)
and your ESC futaba connector put to receiver (chanel 3)
you must use TWO batterys for UBEC and ESC
good luck
I didn't need one,.. Probably nothing hapened, because it doesn't have Ubec, that powers your Rx and servos,.. Because this ESC is Opto. You need to buy UBEC (5v). Hope I helped
There are the same as the hobbyking ESCs. There are instruction files how to do programming. Very easy. Make sure you do it at 3S only because they tend to overheat when in programming mode. Any 5V supply will do.
Opto means no BEC and so you HAVE to have a separate BEC (also callled UBEC) for it to work. HobbyKing has many to choose from. I like the 5 amp UBEC's.

BEC just means "battery eliminator circuit" which means it supples a receiver friendly voltage from the flight pack. UBEC SBEC are the same things and just mean that rather than being a BEC built into the speed controller they're seperate components. The reason for this is that some speed controllers (ESCs) are opto which means the input and output stages are seperated electronically. This makes having a built in BEC difficult so you use a seperate UBEC/SBEC.
My 50 amp Red Brick on 4S stops in mid flight (works great on 3S every time) even though the amps are fine, like it overheats. I thought the timing was low but when I look at the manual, the default setting is high. I guess I'll just need to use a 60 or 70 amp ESC for my edf setup. It's a 4900kv motor w/ 5 blade fan.

Hi guys, it says there max amps is 50A, is that the nominal max working current or the max burst current? like the SS series 40-50, nominal 40amps burst 50amps. some help would be nice. Thanks
Opto bedeutet,Du brauchst einen Empfänger- Akku als Stromversorgung für deine Anlage!Ein BEC-Regler versorgt deine Anlage mit 5 Volt und spart somit das Gewicht des zusätzlichen Empfänger Akku!
ok i cant seen to be able to understand how to program this ESC, i connect to reciver on Ch3 then the motor turn the radio on and then connect the battery i hear this unregular beeps for 7 times and then it loops again but the motor doesnt seen to do anything can someone help me figure out what am i doing wrong?
julio you do not need to program the ESC it is all ready factory set. So once you have it setup correctly it should work. Now for your problem I need more info so ask more question please. There is some thing wrong (DERRRR). Have you plugged it into your receiver correct. Is it powering up your servos. Have you turned on your transmitter before you plug your battery. I hope this helps.
Kevin's answer is essentially correct...Opto ESC's have no BEC, but the term "OPTO" also means that the connection to the reciever is optically isolated, resulting in less chance of interference from the ESC to the receiver. There are some fellows who won't use anything BUT an OPTO ESC. The disadvantage is, of course, that you must provide a separate means of powering the receiver and servos, either a UBEC or an independent receiver battery.
thanks a lot for your responses :)) I understood ...
if I buy this item I have to buy a ubec because of energy of receiver. I'll make a zagi for the first time so I asked ... Thanks a lot ...

11-23-2011, installed in a Horizon T-28 with a Power 10 motor, and Castle 10A UBEC. Power is from three new, charged, 3S, 20C, 2200 Zippy batteries. Works just "OK"; the Red Brick 50A shuts down immediately on some batteries and not others. The problem is IT IS VERY DIFFICULT TO CHECK THE DEFAULT SETTINGS IN THE ESC. It is VERY hard to interpret programming steps in the one page of instuctions. These need to be rewritten.
Es exactamente el mismo variador que el birdie 50A, solo cambian los fets y que este no tiene bec, funciona bastante bien y aguanta mas corriente que el birdie.
