The DP 3A is a tiny (around 1gram) brushless speed controller built only for single cell applications and for current draw up to a maximum of 4A bursts. This brushlessesc is only to be used for Lipoly single cell applications where no more than 3A constant is needed.
Features. High speed MCU. Fast resolution for snappy throttle response and excellent low speed timing. Cell Protection, signal lost failsafe. Smooth startup. Linear Throttle Supports 240,000RPM (2 poles) / 40,000RPM(12 poles)
Note* Please be careful when using this product. Due to its size and delicate nature it is easy to overload this ESC. Only use single cell Lithium Polymer batteries and never draw more than 3Amps or never more than 4A for more than 10 seconds.
I would suggest perhaps doing a bit more research before you dive into a slightly advance project like a Quadrotor. For the battery as long as it's 1s and has the capacity you like. For motors, as it says in the specs, a max draw of 3A, and can produce enough thrust to get off the ground with the proper Props.
5V is definitely too much for this ESC, as I just found out the hard way. Tried to preprogram it using a receiver with 5V - after 30 seconds of beeping it suddenly was dead. I would not go above 4,2V. Now I have to get another one and be careful this time.
Everything worked fine when first installed, now, i'm getting a constant beeb from the esc and no motor action. I have the AP 2.3g brushless motor and a 250mah 12c(3 amp) single cell lipo. What could be the problem?
Can anybody tell me the difference between the different modes. I mean I have now to controllers one of them is in soft start and the other in fast start and the one in soft start consume more energy and give more force than the other.
Why is that?
Another question, which is the correct manual to configure this controlles 3A ESC or 3A ESC V2.1
I have the answer on your second question. The correct manual can you find under tab FILES (right top corner above this discussion). There you'll find two manuals, they are the same (1st one is in .doc file and the 2nd one in .pdf file). I recommend you the second one.
bought the 3 amp xp. it worked great for me, the reviews and specs of both look about the same. i think that the only real differences is that this one's motor connects up rather then the 3 amp xp's motor connects straight,out but the 3 amp comes with a couple of connectors so that u can do the same. so there for my opinion is that there the same. hope this helps
Hi, is there any way to reset de esc to the default programing?
I entered in programing mode by mistake and i should have done something wrong, because now the motor dont run.
I turn it on, ear some beeps, give some throttle, tho motor seems that is going to start, but it don't and the esc starts to get very very hot and I have to do an emergency disconnect so it doesn't burn.
Any tips? I'm completely lost here
the speed control marked with "206B" IS PROGRAMABLE!. the file may not show the table until the view is changed, when I first opened it, it had instructions showing, but did not display the settings table. after changing the view with the small icons in the lower left of the downloaded file window, I got the parameter table. I did not hear the initial beeps described, but after moving the sticks in the prescribed steps to enter the program mode it did begin to beep once every 2 seconds. selected the "fast start" setting of value "1", moved stick to center and it started asking for a break force setting with 2 beeps every 2 seconds. the motor on my plane had taken about 4 seconds to reach max rpm before I programed this speed control, now it behaves differently, throttle responce is better, but still not quite what I want. selected the following values: start mode=1 break force = 2 acceleration mode = 1 timing advance = 3 cutoff voltage = 2 cutoff temp = 2 protect type = 2. I am using this speed control with the Micro Power system w/ Gearbox GPS-C03 I may need to tweak my selections to get better performance, am using a gws "EP-7035" prop. If anyone has tweaked this speed control for that motor and is happy with the performance, I would be interested in the settings values you used.
I have walkera 5G6-1 (2,4GHz) and wish to convert to a brushless power. Can i use this with Brushless Converter Plug-n-Play Specifications: Weight: 2.1grams Dimensions: 23x 13x 4.5mm Brushed PWM Input: Less than 10V, PWM frequency auto detection Signal Output: 5V Pulse, pulse width range 1-2mS, 1.5mS mid-point Power Supply: 5V, /-10%, from BEC of the brushless ESC
They now have another Product, the "HobbyKing XP 3A 1S". This is the 1S3A, like the first batches of these were. And these ones are fully programmable and have better FETs. And the best thing: They are even cheaper! So IMHO this Turnigy ESC is now completely obsolete!
Seems to be two versions. On several pictures (also on rcgroups****) the ESC looks different. There is a label on the back called "1S 3A" whereas Mine looks different than on the picture. I've got a yellow capacitor and I think a slightly different layout (on capacitor on the back is not there). Also the label is "206B"
Mine seems also not programmable...
I'm not happy with it. or with HC selling products not matching description.
Hi, does anyone have experience on using this ESC in combination with the 2g brushless tail (on a 4G3 with brushless main motor)?? What needs to get soldered where? I could really use some help... a picture, schematic.. anything really! Or just some way to get started.
It's exactly what I wanted to do on my 4G3. Unfortunately - despite that the ESC delivered by HK is NOT programmable and has Startup Problems with the 2G Motor - the second Problem is the RX2605 Receiver from Walkera. If you use the 3cable Servo Signal cable (Y-Cable) on this ESC and connect it to the RX2605 Receiver it will take the signal and sometimes be able to run the 2G Motor in the Tail. BUT on the Rudder-Connector of the RX2605 Receiver there is NO Tail Mixing (according to Throttle stick possition) as well NO Gyro controlled Signal!! It is just a linear Rudder signal. The only connector with the integrated Gyro/Mixing is the small 2-pin direct Motor connector (Tail Mot.). I had a small converter (from another NanoESC - converting Tail Motor Signal to Remote Control Signals for the ESC) and tried to use it on the this 1G ESC. Somehow it worked, but because this ESC HAS definately Startup Problems of the 2G Motor and the Startup of the Motor is much to soft, the 4G3 Heli was not flyable in anyway (incredible Tail wag!)... Solution to it all: order the original Walkera Tail Brushless ESC from somewhere else (go hobby-wing). This one can be connected directly to the RX2605 (Tail Mot. Connector) and works flawlessly with the 2G Motor!) Mixing and Startup behaviour is fine and I have my "Full-Brushless 4G3" as I wanted.
(add note: I will use the non-programmable ESC plus another ordered 2G Motor to upgrade my "Minium Cessna" to brushless. On a Nano-Plane the soft startup behaviour of the ESC/engine is less an issue than as "Tail Controller" )
From what I read in the WWW, some people have been able to program it, but I cannot enter the programming mode, either with TX or the card. That said, seems like I do not get the full power out of it either, so it seems to be a stick travel/signal problem. The throttle off is ok, but throttle high I just get continuous beeps indicating that the throttle is not at "full". I really would need to be able to get to the programming mode, to be able to set advance "high" for the 2g motor.... Did not work with throttle reversed, or with some other channel. My TX is from pre-computer era, so I cannot adjust the servo travels high enough. Need some other way to set/reset the "high" throttle position...
As with anyone else, I'd be happy if anyone had any tips. There is also some discussion on RcGroups, under title "TGY DP 3a 1 Gram Brushless ESC ($20!)"
Did some more foolimg around with the unit, tried with another RX. In throttle channel, same thing. In the aileron channel, I managed to get rid of the continuous beeps in "high" throttle setting, but now I only get _one_ beep, and then the 1-2-3 as showing that the ESC is armed. But I do not get _two_ beeps that indicate entering the programming mode.
I agree with Zew that it seems that this ESC is not programmable at all, and the instructions are from some other ESC...
With a servo tester, I managed to get rid of the continuous beeps in "high" throttle setting, but now I only get _one_ beep, and then the 1-2-3 as showing that the ESC is armed. But I do not get _two_ beeps that indicate entering the programming mode. The motor "HXM1400-2000 hexTronik 5gram Brushless Outrunner 2000kv" has difficulties to start. The motor "1404N-2290 1404N 2290Kv 9.2g 3.5A 160g Thrust Outrunner" does not start at all, just makes noise. Without programming I could not use both motors.
The "housing" is a molex 51021-0300, connector terminal is 50079-8000 fits 53047-0300 and 53048-0300 pcb. It is a 1.25 mm spacing connector. I have fitied theese (51021-0300 + 3 x 50079-8000) on servos and used on a Rx with sutable connectors together with the original ESC and its connector.
I have allso made an adaptor to a standard servo connector with an molex 53047-0300.
They are sligtly smaller that the one on the Arrow 2,5 g servo, those will not fit inthe same Rx.
Exchanging the housing might be done but the risk for making a short is high. The force needed to fit the sligtly larger servo in the small housing will peel of some or all of the isolating plastic.
I would also like to see support parts such as the the three pin socket. The 3 pin connector falls between to other JST connectors I use. It does not fit the $pektrum AR6300. I would also like to get the small pins that are used for battery hook-up. Hopefully I'll get some bench testing done today - after rewiring. Roy
This may help using the spetrum AR6300 on one cell I used the connector end that comes with the reciever using two esc's wired together the plane fies 8min or so no problems

I was a bit disappointed with the burn marks on the wiring, they've used too much heat to do the heatshrink.. like using a blowtorch too much heat.
Other than that, these things are fantastic. I removed all the headers and soldered the wires direct to the PCB. Not only does this cut down on weight but also makes it a little bit stronger.
Using 2mm depron a corona 4ch receiver (with some of the headers removed to save weight) and a 2g motor, i managed to make a 15g plane using one of these. Very fun to fly around!

This is a great ESC specially for micro helis eg 4#3B. I could use it with a LOSI 10250 KV main motor. After reprog. the motor starts every time. Forget convert those 7A Ebay and Turnigy ESC This 1g ESC is lightweight and reliable.

The connector for receiver is not JST(?) ,a bit smaller, so it needs to change when use with JST connector. And 3 pin connector for motor is equipped as standard, so it is convenient but can not commonize due to narrow pin pitch ( 2.25mm?) than normal. Weight together with wire with JST & pin connector for Lipo is 1.94g. So this is not bat!

Weighs really 1gr! Used it in my Minium Cessna as Brushless tuning motor. Works quite fine with the 2gr BL und GWS 3x2.
But do not put a 2S Lipo an it. I did it as mistake (just grabbed the wrong lipo). The controller got immediately burned. So I have to buy a new one now...

Beware: They changed the charge. The old ones had 1S3A written on them and were excellent. The new ones 206B. The new ones are rubbish. E.g. they have a CPU, which has a maximum recommended voltage of 3.6V directly connected to the Lipo which can give out 4.2V when fully charged. No wonder, that they often just burn away...Don't buy them, as long as they still ship this bad 206B version!!!
