when I flash simonK to these esc's do I enable boot loader?... thanks for any info you guys can give me.
 Senator315 614 points
No you don't need the boot loader, just make sure to flash them with BS N-FET. Takes 5 seconds.

what is the boot loader for?... or, what does it do?... thanks for the fast reply.
 pono420 74 points
and do I need to power the esc with a lipo?... or will the UBSasp power it for flashing?...
 victorhuge 34 points
If you plan on getting the turnigy usb linker so you can flash new firmwares without removing the heatshrink then enable bootloader. So basically enable it just in case you will need it, why not?

I hooked this esc up with my hobbyking D2826-6 2200kv Outrunner Motor and it gives quite a few beeps and the motor will not start spinning. When I hook up my other esc it works just fine.
 H-KING_SCOTT 5238 points
That is not arming, testing against another ESC means nothing, first thing to do is to lower your throttle trim, second thing is probably to ensure you have calibrated the throttle.....try these before assuming there is a fault.
 pono420 74 points
1# turn your radio on. 2# move throttle to full. 3# plug in the esc. 4# after the beeps stop, move the throttle back down and your done. the esc should work now. hope this helps.

I just tried to program this ESC (F-30A Hobby King 30A ESC 3A UBEC) with the HobbyKing ESC Programming Card (Part number 9261000016) and it did not work. I followed the (very basic) instructions: I set the jumpers on the card, plugged the motor into the F-30A, plugged the battery into the F-30A, then plugged the card into the F-30A noting the correct polarity. Instead of beeping once it gave three low beeps, but it's not taking the program of the jumpers! Then I programmed following the time consuming radio throttle procedure (which worked fine). HAS ANYONE BEEN ABLE TO PROGRAM THIS F-30A ESC WITH THE HobbyKing ESC Programming Card (Part number 9261000016)???

Maybe this might help those wondering how to program this type of Esc, the video uses a different esc, but the principals are all the same. I myself have a few of these on order, as well as the card.

a motor consuming 26amp at full throttle, will this be enough for it
 canterburyflyer 112 points
Yes it will. Unless the load is continuous. You won't be on full throttle right? Don't bury it in the fuselage. You might provide a source of fresh cooling air as well. It is a well made and reliable ESC.
 TheThomass 185 points
I have used this ESC on a EPO Parkjet. It's a 60cm span plane with a 24 gram 3000kv motor spinning a 4.75x4.75 prop. That combined with a 3s 1550mah lipo gave me 6min of flying, all the time WOT lol Never had any problem, never got very warm. This thing flew almost 60mph on less than 30A

Thanks,but I've tried default 2 times,going to try again. Once i lower the throttle to corresponding tone do I just unplug battery then tx? It does not let me do anything once I've lowered throttle.
 BenC_1981 53 points
Yes, then plug in as normal
 Roger 2711 points
Hi Krash1, after lowering the throttle and a beep confirms your setting, unplug the esc from lipo then plug it again after a few seconds.
Krash1  1 points - 6/6/2013
 
I can.t change cut-off protection from Cut off power to reduce power mode. I followed all the correct tones and lower throttle but still cuts out motor when theres low voltage?
 Roger 2711 points
Reset it to default, the procedure on how to is written on the manual. The default behavior for low voltage is to reduce power.
Frankie11  1 points - 6/4/2013
 
which Simonk firmware? BS or. BS N-FET ?
 Roger 2711 points
Use the bs_nfet.hex file.
 canterburyflyer 112 points
Roger is right. That is the one I used. You may confirm by getting the most recent version of the ESC Reference Chart. Same for the F-20 as well.
Chandrahas  1 points - 6/3/2013
 
Also what's the refresh rate?
 TheThomass 185 points
I think 50hz stock, but 400hz when flashed with SimonK

Will I require a programming card for this ESC and if so which one would suffice?
 Roger 2711 points
A programming card is optional. Settings can be easily programmed using transmitter sticks. But if you want an even easier option, use the HobbyKing ESC Programming Card PRODUCT ID: 9261000016. Can be seen in the recommended accessories above.
Martin  2 points - 6/2/2013
 
is this esc a good choice for a easystar fpv plane with a Emax 2450kv Max Amp: 25 A? I have had some "cut-off" problems when i only had one lipo for both the plane and the fpv-gear, and i guess it had to do with the 30a esc. Anyways, it would be great if i got help with chosing a good esc for the plane! :)
 eddfoo 471 points
If your Fpv gear is drawing high load, it is advisable to have a saperate bec to drive it. This esc will be ok with your motor, rx and servos. Look at this ubec: PRODUCT ID: HK-3EC01 to provide extra omph for your fpv gear.
mike_o  60 points - 6/1/2013
 
Warning: The top 45kb file is NOT valid for this ESC. Do NOT use it for programming. Use the 197kb file further down the list, as this is correct.

I'm having a hell of a time trying to calibrate these for a tricopter. I have no idea if they're calibrated or not, and the manual explains nothing about calibration.
 Roger 2711 points
If your referring to throttle calibration. It is mentioned in the manual. Turn on your tx and set throttle to maximum. Power up your esc/motor, after the first beep, set throttle to minimum, that's it. There are sets of sounds for each different settings, the first set is for throttle calibration.
BEST ANSWER CREDIT AWARDED
 Jake 6 points
Wow, yeah I even saw in the manual the first four sets of beeps being throttle, but it didn't register. I needed to see the exact words "throttle calibration," I think. Thanks Roger, I appreciate it!
 Roger 2711 points
Thanks for credit Jake. The term "throttle calibration" wasn't really mentioned. Just Music 1 - Throttle - AAAA at the instructions section for settings at page 5.

are these better than the plush esc's?... i want to flash them with simonk firmware for use on my fpv quad.
 Roger 2711 points
If flashed with simonk, this ESC will perform better than the plush esc.
 pono420 74 points
so a flashed f-30A works better than a flashed plush esc?... thanks for the info.
 Roger 2711 points
I don't have any experience with a flashed plush (blheli), but with the stock f-30a and a simonk flashed f-30a, the difference is very noticeable.
Chandrahas  1 points - 5/31/2013
 
Was wondering if these will work fine with hexTronik DT750 Brushless outrunner 750kV?
 Roger 2711 points
Hi Chandrahas, this ESC will work great for the DT750. It exceeds the recommended ESC which is only 20A. With 11x4.7 Slow Fly Prop and 3S lipo, max throttle can draw about ~19A. It is good to have some headroom so your ESC will not be too hot.
 TheThomass 185 points
Yes, but I use the 20A version (F-20A)on a tricopter (RCexplorer design). 3s 2200mah lipo, kk2.0, DT750 motors, F-20A esc's, 11x4.7 or 10x4.7 props. Flies great and carries a gopro with ease.
BB879  7 points - 5/31/2013
 
Is this a good ESC for the HobbyKing S2838-2800 Brushless Inrunner (2800kv)? If not, what do you recommend?
 eddfoo 471 points
Your motor max amp is rated at 22A, this esc is ok. You may also need the programming card for this esc to set the configuration you want.
Adilson  1 points - 5/30/2013
 
would i be ok building my quadcopter with the following**- Turnigy nano-tech 3300mah 3S 35~70C Lipo Pack Hobby King 30A ESC 3A UBEC and Esky Brushless Motor For Helicopter (Prepositive) 3800KV
 BenC_1981 53 points
The ESCs will be fine, as will the battery. But the motors* 3800Kv?? Yes, they're light, but why such a high Kv? At 11.1v, they'd be rated at 48,000 rpm. That's just nuts! Go for something like the NTM 28-26a. Much more proven on a multirotor. (PRODUCT ID: NTM2826S-1200) and they're about $10 each cheaper than the esky motors.
Daniel  4 points - 5/30/2013
 
I have connected this esc to my motor and when i started it, I noticed, that the motor did not have so much power than with the old esc!! What did I do false?!
 BenC_1981 53 points
You may need to program the throttle range on the esc. Connect the esc with motor, and then turn on transmitter, and set throttle to max. Then connect the esc to a battery, at the first beep lower the throttle, wait for beep then disconnect battery from esc. All done..

What is BEC and UBEC? What's the difference?
 BenC_1981 53 points
BEC is Bttery Elimination Circuit. This provides the electronic (receiver, servos etc) with a friendly voltage (usually 5v) from the flight pack, but only at a max of about 2-3 amps (it will say on it what it is). A UBEC is a Universal Battery Elimination Circuit. This is a standalone component not built into the esc and can provide a electronic friendly voltage at a much higher current. A UBEC would also eliminate a model dropping out of the sky if a cheap esc Fails. Useful on Larger models. Ether basically does the same thing, it allows you to run the servos & receiver etc on the flit pack instead of a separate battery pack.
 canterburyflyer 112 points
Yes BenC_1981, but what might be confusing is that, for instance, I have a HK Redbrick 30A ESC and it has UBEC printed on the shrink wrap. My new F-30 ESC's also have the same thing going on. It is confusing me as well. Opto, SBEC, No BEC, and UBEC. Glossary of terms is a definite must for the beginner. And then the exceptions must be observed :)
 BenC_1981 53 points
In use, there is no real difference. Most BEC are linear, so they waste the excess energy as heat, not too big a deal a 2s or 3s pack, but if you step up to a 4s or more pack, then you start making a lot of heat it he linear voltage regulator. UBEC was originally a brand in itself (Ultimate BEC).
Tatch  2 points - 5/28/2013
 
Do you need to have programmed this ESC before it will allow you to start the motor? If you don't programme it then by default are the factory settings not sufficient to allow the motor to work? I haven't programmed it yet and when I started it in working mode nothing happened. Is this normal???
 Senator315 614 points
You need to set the throttle end point. Set throttle to max, power the esc with a motor connected, at the first tone lower the throttle. It will now work.
BEST ANSWER CREDIT AWARDED
 canterburyflyer 112 points
No it is not normal and you don't have to "Flash" it with different firmware to use it. Certainly not for use on a fixed wing craft. But they aren't very good for multi rotor use without it. What are you using it with? I have had them fail right out of the box because of sloppy soldering but you would either hear and smell it if it burnt upon power up. Since I am unable to see how you have it hooked up, you had better give us some more info. You sure you have it wired right?
 Tatch 2 points
senator, thanks - i did that and now it works, so are all the other default settings okay for a 3 cell lipo? Is there anything else you recommend i programme??
 Senator315 614 points
If your using for anything other than a multirotor then the stock settings should be fine.

Hobbyking should correct the packaging-weight. It's exactly 32 gramm with anti-static-foil and 31 gramm without! This is packaging difference around 50 % !
 eddfoo 471 points
The 47g stated is the shipping weight. When you buy one, it comes with a little box, the extra wt is for the box.
 -ghost- 3 points
Ok, that would explain the weight for 1 item, but if you order more than 1 it will be added 47g for each item. And that is definetly false.
 (Mike) 564 points
yes as a matter of fact hobbyking do add the postage but when ever you receive your package it will always be over the weight displayed in cart unless some major items are missing.

Hi guys, can I use these ESC with "Turnigy Multistar 4822-690Kv 22Pole Multi-Rotor Outrunner" w/4S lipo?
 Roger 2711 points
Yes you can, based on specs, both esc and motor are capable of running at 4S. Motor also was designed for max current of 22A which makes the 30A ESC suitable.
 (Mike) 564 points
what prop will you use, the max stated is 22amps as roger stated but it can go over 30a if the correct prop size is not used, this esc will handle it anyway, if in doubt go for the 40amp esc instead.
Jessie  1 points - 5/22/2013
 
Im new to flashing and programming esc's. My question is, do/should I program esc with card after I flash esc? I've already flashed esc with simonK firmware and not sure if I also need to program it. Oh, this is for my tricopter build.
 Roger 2711 points
If it is already with simonk, no programming is needed or available, except for the throttle endpoints.
BEST ANSWER CREDIT AWARDED
 canterburyflyer 112 points
You cannot program with card after you have flashed with firmware. No going back either. Once flashed, its permanent bud. Besides its already miles ahead in terms of performance. Amongst other things, you need to calibrate ESC's with Tx and board. If you can think and type the question then somebody has probably uploaded a video tutorial for it. just google "ESC calibration with _____ board" and see what you get OK? you'll be just fine. BTW without doing this you wont easily be able to arm or disarm etc., etc. Your almost there!!

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. :)

It is worth spending the extra dollar or so to have the 3.5 mm connectors already on these esc's. This was money well spent and can handle the rated 30 Amps.
