Hi, Just bought a brushless motor and esc for first time. The wiring is a bit confusing as the motor has 3 wires red, yellow and black But the esc just has 3 wires all blue. Does it matter which wire goes where.Sure this has been discusse before but I have never ventured into the brushless world

Wired up my brush less motor and esc as per the article from Colin, however after several beeps sometimes the motor runs and other times nothing. Using Tamiya gold connectors Any clues as to why it doesn't run always. Have charged the batteries too (7.2v NIMH) The rudder servo works fine all time.

Help plese

Chris. Do you have an aircraft forward only esc?? they need to be started with the throttle FULLY DOWN (stick and trim (if you have a trimmer), or it will only bleep at you.

Getting a program card is essential in my view, They are the easiest thing to use, and you can ensure the esc is set up correctly and looking at your battery the right way. If that sounds silly, these esc are cleverer than the brushed ones and start to go funny if the voltage drops or they get hot or…or…

Ashley, Yes I do have an aircraft forward only type and "success" I followed your suggestion and it works so very many thanks. I think I will get a program card though how does it work and what does it plug into. The esc only beeps at me and no instruction as to what each beep means, Pleas keep up the help. I NEED IT. Begining to wonder if all this brush less business is worth it,but will persevere for a while.

There's some expertise building up on the forum about the operation of brushless motors – as you've found out – so there's no need to panic.
The programming card typically plugs into the main battery pack and the ESC – you don't need to connect the receiver. You can then set the speed controller for various parameters such as direction (forward or F+R), cut-off voltage, timing etc. I have two different types and both came with comprehensive instructions. There's also a wealth of videos etc on You Tube. Here's just one of the better ones **LINK**
If you buy the correct items for your model and follow the instructions then there's no reason why you shouldn't have total success. I did!

Hi Chris, it's well worth persevering, for many models they are excellent. Once you get over the initial learning curve and sort out what all the numbers are about you'll find them easy enough.

You don't say what motor and ESC you have, a link to them or just saying what they are will help with replies and help others later. I'm curious about what model you are putting the motor in as well.

Hi, The motor is an A2212/6T and the esc is marked as Dongxingwei 30 amp.(on the back of esc is number E203950) I bought a package of motor, esc and motor mount at what I think is a bargain price of £10-30 on ebay.(begining to wonder about it now) I have contacted the seller asking for details of the correct program card but no reply so far. Any help please. The model is the RAF Air Sea Rescueby Ron Rees in balsa( free plan in Model Boats) Keep up the help please

Hi again. Having some difficulty in obtaining a program card specific to my motor/esc. Is it essential to get a 'card' specific to esc of will any card do the job Chris

I doubt that there's such a thing as a "catch-all" programming card – although I'd be quite content to be proved wrong. If such a beast did exist then the Google Spiders would have found it for me – and they didn't.
As you suspected, your bargain buy may have turned out to be anything but. I've found that the motors you have bought are generally sold for drones i.e a "forward only" application, and there's no detectable programming card for the corresponding speed controller. I've also been unable to find any programming instructions on the web for those ESC's which you could do from the transmitter, using the "beeps".
I have cards for Fusion and Leopard speed controllers and both are available from UK suppliers, so if you can't obtain reliable results from your set-up then you might consider one of those options. HobbyKing might turn up some others but you won't, however, get a compatible motor and speed controller for a tenner.
Having said all of that, if the damn thing is working then just go with it!

Dave, Much as I don't want to I reluctantly have to agree with you and the £10 bargain ISN'T . I got a sort of reply from the seller saying he will ask his supplier, but I shan't hold my breath

It works after a fashion so as you suggest I'll just go with it. Its only a winter project anyway. Thanks for all your effort and input

your esc seems non existent with or without its number?

Seems when I reply from my email address I get a Postmaster @mytimemedia message saying can't find and send failed so hope this reply makes it. Agree with Empire Parkstone that I won't get a program card for my esc so will just have to accept it and go with what I have. Its only a Winter project anyway. Many thanks to all for the help, however I reckon I'll stick to brushed gear ( I understand that a bit at least Chris

Don't write off Brushless Chris they can be the bees knees . I was very reluctant about them till I tried One to replace 3 powerful brushed ones .Your motor is online you could try a cheapish brushless esc from the likes of Hobbyking plenty cards there as well
