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: 5v / 3A Cells: 2~3s Lipoly Size: 47mm x 9mm x 33mm Weight: 29g (Inc Wires)
Try cutting off the cover, removing the heat sinks, and checking the rubbery thing that covers the electronics. On mine that rubber piece had worn thru and was touching one of the battery contacts (it came from hk that way) and would get hot and cut the throttle from time to time. Once I fixed the rubber thing it worked fine and only gets warm.
Hi all, I cut the heat shrink off and flashed it with SimonK. I had a pretty good increase in RPM with an 8x6 prop driven by a turnigy 2632 1500kv motor. Also a good time to check and see if there are any issues such as 2beer mentioned. All the best and Happy flying!
mtjoeng, Do a search for, [openpilot RapidESC Database]. This is where the spreadsheet is that I use. Bookmark it for future use. Anyway, on this ESC you'll need, rb50a.hex. Hope this helps and Happy flying!
I've bought 2 of them myself at different times and there the only ESC's I've bought off hobbyking that work! I suspect your causing the problem? mine worked perfectly straight from the package, I know they have a reputation as troublesome, but mine have worked great, I regularly pull 48amps through them and so far so good!......... it seems the newbies are having trouble with them the most when setting up their planes.
Eu estou com o mesmo problema, esse é* o segundo ESC de 50A que eu compro na HK, o primeiro (uns 4 meses) funcionou bem, mas esse que comprei a uns 40 dias está* com esse mesmo problema...
Algué*m sabe dizer se dá* para aproveitar o UBEC dele? É* possí*vel separar os circuitos?
10 thumbs up!
I bought this esc after downloading the manual from the Files section and making sure it has the Brake function required for my Sailplane.
1- The manual that comes with the ESC is completely different from the downloaded manual: only 3 programming options versus the extended option fron the downloaded manual
2- The manual specifies 3 time beep per option. The Esc only has 2 time beep per option.
3- The manual shows how to change the Brake (third and last option). There is NO BRAKE.
4- I now have doubt whether the Battery selection option 2 for LiPo is working. I won't risk a fire is this option is not activated as per my programming as in the Brake option
In conclusion: misrepresentation of product. Value is bad since Price Shipping $ and it cannot be used.

Tried this one this yesterday: very deceiving. I measured 44 amps at home and during the flight, after a while, the engine stops with a noise. Lowering throttle to minimum then back to original position the engine restarts, but this is not healthy. I have been borrowed today a HK 40/50 Amps without BEC and it worked fine in the same conditions.
I checked the programming option to be 200pcnt sure : very simplified. Only 3 choices : NimH, Lipo and Break. The provided owner's manual was not so clear but fits the ESC possibilites.
I did not check user's reviews before purchasing, I should have.. Only 10 USD, but for me 10 USD thrown away...

Can't give this zero score, if I could I would. Connected it up servo worked OK but motor would not turn..... Tested the motor with another ESC so my red brick ESC is duff. As like others mention on here not worth the postage to return.... but I'd steer well clear of these in future.
Very fast delivery to Austria (11 days), but: like other people have written already this is a faulty esc. In my case it never operated, only three beeps in the beginning. I have a lot of esc, the turnigy (plush) esc are the better choice. Not worth the postage to return.

Bought it as a spare for my main Turnigy Trust 55A.
It stopped working after a couple of flights whereas the Turnigy is working non-stop. I won't be buying any more Red Bricks, I should have supposed why it had such a large heatsink > bad design (or I got a faulty one)
