Really bad ESC. Stock firmware - not working. Can randomly freeze. And no one custom firmware, in case it is based on atmega48v.

Alexander, I flashed mine with SimonK and it works great in my F-22 but I have to land when I hear it slow down. I would recommend getting a buzzer for it to avoid damaging batteries.

It is nice to hear, that your RB50A with ATmega8. But mine based on ATmega48V and can not be flashed.

Tá* com defeito este ESC. Ele corta o motor do nada ! Tem mais pessoas em Ribeirao Preto com o mesmo esc e com defeito !

Why must you always lie when it comes to the weight of things? It weighs 38g, not 29g as stated. :-(

It is like it is ... But if you fly a model that uses 50A than 11g wont make such a big deal for you
 Frank B 21 points
That doesn't matter. A store should not lie about their products. It is unprofessional to trick people into buying stuff by labeling it incorrectly. When I buy something that is labeled 29g, I expect it to weigh 29g. I bought this ESC especially because I wanted a light one, and what did I get? Fooled.

Don't worry too much frank, after you use it a couple of times it will go faulty anyway!
 Mario 145 points
Ral you are not right,these are werry bad esc-s but mine is working still after one and a half year like new :)
 Ral fRotten 2049 points
good luck to you mario, I bought 2 of these and neither lasted more than a couple of flights, I don't buy HK esc's any more, of the eight I've bought only 2 still work!
 Mario 145 points
well,red brick and birdy are the cheapest and you will get one of 10 that will work like mine...Turnigy plush,turnigy platinum,k force ... these are extrely good esc-a and blue series
 Ral fRotten 2049 points
I don't know about the birdy I've never bought one or the turnigy's, I've bought 3 blue series with the programing card and I have 1 still working, I,ve bought the blue series, the 30amp hobbyking, and the 25amp ss series, and the red bricks, only ones still working are 1 30amp blue series and 1 25amp ss series, I no longer buy ANY HK ESC's, now I buy at ebay for a 30amp mystery esc's they cost about $7 delivered I've just bought 2 for $12! and I've never had a failure, also the 60amp mystery esc for about $18 delivered, the turnigy's are more expensive than the mystery esc's so I've never tried them,, for the 60amp esc's Ive been using Jetpro's there about $16 delivered on ebay but they changed the name of them and the price now is around $18 too, I have about 18 foamy models and all use between a 25amp and a 60amp esc, Like I said Mario you have been lucky :)

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)
