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.
The Red Brick ESCs have been engineered with heat dissipation in mind. featuring twin heat sinks, the Red Brick ESCs are slightly larger than many ESCs in their class, however this compromise in size is aimed at assisting to eliminate the problems associated with over heating.
Specs. Max Amps: 25A Ubec: 5v / 2A Cells: 2~3s Lipoly Size: 48mm x 8mm 26mm Weight: 20g (Inc Wires)
Actually, the motor would do the harm to ESC - ESC is too weak for the current, the motor would take from it. Well, you still can use this combo if you downsize the propeller so that the current won't exceed the 20A (you will use only about the half of the motor's capacity). But much better option - use the 40A esc, or, if you're into the multirotor, 30A would do the job (because the motor is used for 100% only for short bursts), but 40A is safer anyway.
almost all the esc have the same program.Did you check the youtube? i am sure that someone has allready upload the beeping patterns. 1 beep ceel type check 2 beep throtle check 3direction and cutoff type check 4 timing mode check 3
How to shutoff the fail-safe throttle?
Everything is working fine, but with throttle down to off and turn off the tx, the ESC powers up the motor to about 1/2 throttle, this looks like a built-in fail-safe, can it be turned off? How?
Try changing the failsafe setting for throttle on your radio transmitter to zero ,it goes to a default setting in case the signal is lost ie when u turn the Tx off
Tell me which Tx are u using so i can help u better
Fernando, you are right: they are desabling the fuses reset so we can´*t reflash these ESCs. I had this problem with a 10amp ubec from hobbyking: impossible to reflash it.
I can confirm that this esc runs with simonK s custom firmware!
I used the tp.hex file.
The only bad thing is that this esc doesn't have a pins to connect the programmer to.
You have to connect to the atmega8 directly
anyone who flashed this esc with simonk firmware can please tell me what .hex to flash and where's the pin (MISO, MOSI etc etc..) on the board... Thanks
first thing you need to do before anything is to connect to motor, and RX, Turn on tx with throttle in DOWN POSITION, yes Down not up, and listen for two beeps, do this for however many you have it will sync them all, if not you will have problems
Hello,
would it be possible to buy 4 of these and use them for a quadcopter with motors that take max 17amps. Are the reliable and will they fit quads with right out the box configuration?
Thanks
I tried flashing Simonk's code but it didn't flash.
I've already read something about locked fuse bits. Does anybody knows about it or has has better results?
my new RedBrick 20A looks other than before. But seems to be simonK flashable too. At least the MulticoterFlashtool works normaly. But i did'nt try to fly yet.
that is good to hear. i just got 2 of the new batch and they have little isp pads on them now. will order 2 more to have the set of 4. may take it a step further and design a board with all 4 ESC on one board. i want to replace the top plate of my DJI F450 frame with it and have mounting holes for the diy drones APM. i want all 4 ESC to have the same incomming clock for better sink-up
if you need some thing more then "out of the box", like programing etc.. then get a better one.
This one is the low end of the ESC it works good for single engine, I wouldn't even try airplane with 2 engines with this one.
Switching speed and PWM frequency are two different things...the pwm fequency(400hz for multirotor use)..is the speed at which the updated speed can be communicated to the ESC by the receiver or the FC...but switching speed is the FET switching speed..i.e.. at which the motor is being commutated for operation..or the spedd at which the ESC updates the motor speed...these esc's need to be flashed with the Simonk firmware for proper multirotor use..
These are linear ESCs. I didn't have to cut off any of the wires, just had to solder the bullet connectors to each end so that it could plug into the motor and the power distribution board (or battery plug if you don't get the board.)
I have had success with this ESC in standard config (no reprogramming) on a homebuilt quad with DST-1200 motors,8x4 props and KK board, have had no issues at all. You will need low voltage alarm to stop quad falling from sky.
Do any of the programming cards that HK sell work with this Red Brick ESC? I have no idea if this is set to low-voltage cutoff, but I'd like to turn this off and/or set it to NiMh so my quadcopter doesn't fall out of the sky.
This ESC is best suited for beginner/entry level. It is like plug and play option in you windows. Very basic setting can be done with the help of TX/RX. So if you need more programming option then go for some professional level ESC. Hobbyking is providing very good solutions and combos at very cheep prices.
Seems to work well as it comes. But have tried various methods of programming,I would like to set factory default - reset, but haven't had any luck. Beeping sequence is totally different to reviews and youtube.Has 2 single beeps followed by 2 double then 2 triple beeps. Then goes thru same sequence.Dosnt play any tune when powered up. I have got a problem, I have got 4pcs, 3 work well but one i set something bad, and not the motor go on and of how it wants :(
Thank you
Hobbyking products are not only low on price but high in quality. So they also offer you to send it back and return a new one if experts think fault is there with any reason connected to customer negligence.
individually connect the ESC to the Rx and get the throttle all the way down..... and switch it on.. once done the same with all the ESC then connect to the board
plz guys I a beginner and need help!
I should pick a ESC that has more amps (Bigger than needes) right? is this one has more amps than I need for the (AXN-2208-2150) ???
You need to find a compromise between capacity and weight. In my opinion, the ideal for this engine would be a 25A ESC. But this can be a good choice because is lightweight and supports the max current of the engine.
is not huge! But it's always good to have a margin of safety! You've reached this model: www.link is more robust. If you plan to use this ESC in another larger model in the future, this is a good option!
You can use him, but you cannot let the motor work on 100pcnt... then you will have problem, bcs the amps... and esc will be overloaded and then will be broken
Motor requirement is of 20A. Hobbyking also ship their product with 20A ESC. I think you can easily use this one as its max current handling is 25A. So you will be good to go and no need to worry.
Ordered this ESC to use with my depron trainer model. I had issues using HobbyKing SS 20A ESC with 2S batteries. Hopefully this one won't have such issues.
