And what is your point Muhammad? I haven't got the data sheet at my avail. UBEC, BEC a matter of terms. But really what is your question, or statement implying? I am using these exclusively and would like to know all about them!
I am using these exclusively as well and never had any issues. Very nice ESCs. Not asking a question, nor am I making a point. Just saying.
Regarding Data: per the datasheet, the LM7805 is rated at 1.5A max. There are two, so you're getting what is advertised.
BEC refers to a linear regulator, while UBEC/SBEC refers to a switching regulator. So it's not just a matter of terms.
If you push these ESCs, then the difference becomes more critical. We know that switching regulators are MUCH more efficient than linear regulators. If you draw 3A from a switching regulator, it will get warm. However, if you draw 3A from a linear regulator, it will get very hot. On something like an ESC where heat sinking is focused on the FETs and where high temperatures can lead to failure, this can become an issue.
Of course, this is not an issue on multi-rotors, which is where I use them. Powering the FC and RX is about all I need the regulator to do. This is a very manageable load for these regulators.
There is a thread somewhere on RCGroups about BEC mis-labeling and how to tell what you've really got inside.
THanks Muhammad, Very useful and prompt as well. I didn't have the faintest idea this was a matter of concern. And it is not that I don't have my hands full as I wade into the deep waters of APM FC and all its peripheral components. I am going mad reading all the posts and varying points of view. All I wish for is to be able to get my Quad and Hex off the bench without frying anything before I get a chance to do some critical trial flight and data cining on the set up. It is like Jabram says about the "Firehose" of information :-) Thank you for telling me the straight facts on the LM7805, I will go and check out the Data Sheet and get polished on the topic. But honestly, where will I get the time? Godspeed and Good Flying to you sir. I wish you well. Regards C. BTW I though after reading my post that I sounded rather rude. And for that I apologize...!
Me too, are you aware of all the recent FW updates to various ESC for different motor timing applications that SimonK has posted on his Github site? There is more going on there than you can shake a stick at. Down side is that I can't figure out what release goes to what ESC/motor combo yet, I really have to take the time to do so. I have 6 new Turnigy 5014 530kV motors coming and there is a solution for the use of the high pole count motors that are as recent as September 20th or better. If you haven't already found this repository, just "Google">>> simonk tgy <<< and select the first header in the search results. MAybe you can make out what it is all about. All the best and thankyou for the points. I need all the help I can get Muhammad :-)
LM7805 will obviously get more hotter the higher amperage you drain from it. There's two of them connected in series with oscillation dampener resistor which doesn't help with the efficiency. The wattage used to heat the linear regulator is ((battery voltage) - (output voltage)) * (output amps), so for 2S1P lipo and couple of servos using 1A constantly, the LM would produce heat (and drain battery!) for (8.4V-5.5V)*1A=2.9W, small soldering iron will work with 15W! Switching BEC would produce only about 0,15*(5,5V*1A)=0.83W
Openpilot forums, rcgroups, even you tube have great tutorials to flash your esc to simonk. Do you have the proper atmel socket programmer from hobbyking? Here is a video
Very good ESC for quads! I use four of them with SimonK firmware. Update process was smooth and doable. Now the ESC are silent due to higher switching frequency, which also means faster response time! Very robust design with large and long multistrand wires. SETUP: 8x4.5 CF props, d2830-1k motors, 800g AUW with gopro2, I get about 12min of flight time with 2250mAh turnigy battery.
Henri, I hope you don't mind if I bud in here, I was intrigued with your tinyurl address and of course I found the ESC Specs for SimonK/BLHeli Quick reference resource which I have used but for little else than for the FW for my favorite ESC the F30 :-) but are you aware of SimonK Github site?
This repository is quite something as I am sure you will agree. He has there, the most up-to-date FW releases for use with various motors and timing issues that are challenged by high pole counts etc. Simply Google >>SimonK tgy<< and then you can select the first header in the results of the search or try this if it gets thru the HK filter (github****/sim-/tgy). I was amazed at what this man has been up to. FW releases and updates as recent as September 20 of this year, maybe more recent as that. I call it a high intensity FW repository. Love the look of it too. Go ahead.... and be amazed!
Hmmm.... It looks like there is a direct link to this github site thru the ESC guide which I was unaware of, so perhaps you must have already been there, done that. Oh well, you can't blame a guy for trying... and here I thought I had this amazing revelation Hahaha :-)
Make sure all of the solder connections are good, you might be able to test the motor with a circuit tester which comes on some multi meters, or try different combinations of plugging in only 2 wires to make sure one isn't broken
I don't see any resolution to this problem and am having the exact same issue. I just ordered Bixler 1.1 ARF (Brand New) and HK 30A UBEC ESC (Brand New) and HK 2.4GHZ TX/RX (Brand New). When I first connected the ESC Motor and RX (With TX on) it immediately started beeping. I have tried plugging the battery in with TX with no throttle and full throttle and I get the same results.
As all of this hardware is Brand New I would not expect any problems and am frustrated this is not working!
I figured mine out. The problem was the ESC was connected to the wrong channel in the receiver. The HK 6CH TX/RX utilizes CH3 for the Mode 2 Throttle. That is to say, the left stick that goes up and down corresponds to CH3 of the receiver. Also worth mentioning, the Trim has to be all the way to - or it will also throw error beeps. Im sure this trim situation could be worked out with the above video* however, the constant beeping is likely an indication that the plane is configured incorrectly.
BTW, the reason Craig is so frustrated is if the ESC is hooked to the wrong channel, moving the throttle will not change the beeping. So no matter what you do with the throttle it continues to constantly beep. It seems so simple in hindsight but so frustrating in real time!
I will attempt to program my ESC now that I'm utilizing the correct channel. DOH!
excellent cheap ESC, exactly as described, easy to program with TX and very good throttle response. I'm using it with a 4200kv outrunner and 3s lipo with 64mm EDF, great setup!. thanks HK

Picked this up a week or so ago the unit came in perfect condition. programming was not required as it worked configured out of the bag. it would be beneficial to have a detailed spec sheet on beep config packaged w eack hk unit sold rather than hunting online or waiting for someone to post. would buy or reco again

I have bought this and receivied few days ago. It was well packed. I had 1 flight with it, and it was good. No problems occured during the flight. After flight it was barely hot. I recommend this esc, because it's possible to program, and it has good price/quality ratio. :)

Good quality and well built, pre progged from box with generic settings, but easily programmed from TX.
Bang on the mark for a speed controller
