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)
2 flights and its gone. Am I doing something wrong or just unlucky. Flew my AXN Floater on a 2200mah 3S Turnigy Lipo, standard motor. First flight great. Second flight, 7 mins into flight motor stops, glide down, land ok, now motor just stutters but does not turn. Is it the motor after 4 flights from new or the ESC. This is already the second ESC, the Turnigy 25A one blew on second flight. I soldered them, Heat shrinked them. What am I doing wrong. I Cant afford to keep buying new ESC's. Has any one else experienced fault ESC's or can any one recommend a possible remedy.
Yep, same experience here I'm afraid. I can't recommend any of the ESCs I've bought yet. Every single one has gone, from a small knock to overheating, some last a few dozen flights, one blew up the first time I powered it up. They are a weak area. I would just buy the cheapest available that has sufficient spec for what you want. I buy 3 for every one I need. They're more consumable than batteries! Oddly, the ones that come in the planes tent to last the longest but never seem to be available to buy separately....
I wonder if it might be where you are placing them. When I first started using ESCs I had the same sort of problems. The motor would cut out. And if I wad lucky I could glide down safely. Or, a couple of times the ESC would totally pack up and I lost everything. I lost planes like this. Smashed. I don't know where or how I learned what I was doing wrong. But, I can tell you that since then I have not had a single ESC fail. You must keep them cool. I always place the ESC outside the plane with the heat sink outwards. I cut some of the shrink wrap away so that the metal heat sink is not covered. This should totally solve your problems. But, if you can, try to use the next size ESC up as well. If it's not working flat out, it stays cooler. Very best of luck to you. Andrew.
Thanks Andrew, that's good advice. I am mounting them like this on the whole. Admittedly they do seem to go after I hit the ground hard though, I have to say! Perhaps it's my flying that needs improvement as well as my building!
Well Kevin, if you are already keeping them cool, I am at a loss. I wish that I could suggest something else. I have had some nasty crashes:-) Always messing about. Always pushing too far. But, I've not lost an ESC like that. I mean, I've reused them and been fine. Have you got a watt metre? Have you made certain that your motors aren't pulling more than your ESCs can handle. I'd be lost without my watt metre. It's all I can think of that might help. Maybe someone else will have an idea.
Me too, I don't know why I keep losing them but they are definitely the item I replace the most. I think I will go for the higher rated ones in future but they are more money and one that I bought blew up the moment I put it on full power even though it was twice the rating of the battery or motor! Luckily they are not a hugely expensive item but I seem to be very good at blowing them up!
You must be doing something. Do you live on a lay line or something? :-)
I remember, I once had a lot of bad luck with servos. I still don't understand why.
I've had a few of these Red Brick ESCs. They seem to be ok. They are basic. But, what do you need? Best of all they're cheep.
Can I ask? How many servos are you running. You aren't running a string of Christmas tree lights off it? No. Of course you're not.
If I think of anything I'll let you know. But, it's normally heat that buggers em. I try to put a bigger ESC than is needed. But, you already said that you do too. Sorry, I'm stumped. But, I'm no expert. I just pick up what I can. If you find out what is causing it, do tell me. Good luck. Andrew.
I've got about 20 broken ones! No idea what is causing it. Honestly it seems to be after a crash that they always go, I have never had one go when under full throttle. Weird. Ah well, they're only about 6 quid each - three more arrived in the post today! ha ha! I'll try to make these ones last ... :s
Hello. It does say 2A in the description. And you can read in the photo that it says 2A on it. But, Hobbyking do make mistakes. Perhaps they have changed the description. I always have a really good look at the pictures and compare what I see with the description. I hope that you can still use it. It's a pitty. Best wishes.
From what I can make out this is the 'new' variant of the Red Brick 30A ESC.
The original variant was 3A BEC (had blue motor wires), this new one (black motor wires) is 2A BEC.
Hobbyking have clearly updated the picture to reflect new batch, but not the description.
Hope this helps
the uk warehouse is only available to uk residents at the moment. as far as i am aware overseas buyers will be able to utilise the uk warehouse at a later date.although i would not hold your breath if i were you.we are still waiting for them to add decent postage options for us. currently we can only use parcel force 24 or 48 hour delivery with a minimum charge of £*8 delivery.not much good if you only need a servo or a £*5 esc! sort it out hobbyking!!
Sorry you had problems mate but at least they sorted it for you right,maybe it was a one off as i've just ordered something else today and it still works ok for me and i'm Norfolk,just thought i'd share that with you and who ever. *-)
Like i've said before i've got a few orders now,one with the Durafly SE5a and another one for the AXN and then a couple of smaller orders for servos,ESC's and a couple of other odds and sods and all with out one problem,guess i must be lucky but i doubt it. How long ago was this when you have trouble? i know they were having problems in the first week or so,then the other day the web pages were playing up because they were updating there systems so people on there ipads and other tablets could order. You should try the HK forums as there is loads of good info on there to help out most people,if not you can always start a thread and ask for help plus HK admin sometimes look through and they can be really helpful. No doubt HK will sort out all the little faults the few are having.
