Sorry for the newbie question but does this ESC come with a built in BEC or do I need to buy a separate BEC (and if so, which external BEC would you recommend)? I plan to put it in HK450. Can it handle 4 HXT900 servos and a gyro? I'm using a DX6i and AR6200.

Has a BEC, but only 1.5 amps. Best to buy a UBEC, as this one starts glitching a bit on 4 9g servos under load. I use it with the TURNIGY 3A UBEC w/ Noise Reduction. I don't think the noise reduction is necessary in 2.4ghz receivers and you can take off the ferrite ring easily. It is working well in my two 450 clones. Use the Turnigy programming card for easy set-up. Good luck!

I ran it with 3 HXT MG14s and a MKS DS480 tail servo with gy401B gyro. It would glitch and cut off. I put in a Turnigy 3/5max amp BEC from here and it ran fine. I had run with the HXT900s and could fly a few battery packs without much problem. Only when I pushed the bird hard did it cut out. So a BEC is safest. I now have three of these speed controllers in three birds and I'm not having any trouble with them with the BEC added. Still a good deal with the BEC for 40amp ESC in MHO.

How do you like the gy401b? is that the HK copy of Futaba
401? Also what radio are you using Iam still setting up my HK450 I want to use my Futaba 6ex 2.4 GHz(I cant afford a new radio yet)any info on settin it up would be VERY helpfull.

Hi Tryin2fly, I am using the Spektrum DX6i. The 401 clone is from ExtremeDeals and it is the same as some the other clones. It holds well with a good servo. Holds pretty good with a ****py gyro too. LOL!! Use the Trex 450 Bible to get links and advice on how to set up your HK. I would suggest using setup videos from Finless Bob at Helifreak ****helifreak****/forumdisplay.php?f=60 I don't see why you can't use your Futaba. Please look into the CopterX 450AE version of the 450 if you want a quality machine for little money. I have the HK too but for 59.99 for all aluminum CNC helicopter kit. That is really good. Ehirobo sells it. Good Luck!!

HI,helimangler
Thanks for the info I posted before but have no idea where it went lol, Anyway the HK is up and running the esc is working great,not hot, no cut out,so far so good for $10.00
ESC you cant beat it!!!I seem to see the copter X name alot I will go and check it out Im still tryin to fine tune the HK (seems to be slow going for me?)the one thing Iam worried about is the tail servo is getting warm not hot but warm it is a hxt900 w/a mks 292 gyro any thoughts on that?(lookin for a cheap dig/servo) I have watched finless so many times I lost track!! great info on that site for all. Thanks again for the info If not for people like you and others on this site to help newbies like me there would be alot of unhappy WOULD BE R/C'ers its good for our Hobby !!!

Hi Tryin2fly,
Thank you and no problem. Hobby King now has the Hobby King 401B AVCS Digital Head Lock Gyro which is the exact one I was using from another place. It is a great gyro!! Set it up right and BANG! Tail is rock solid. I use the MKS DS480 for a tial servo that works well. It is digital. HXT900 is a great servo and warm is not bad for a tail servo. I have not had the 480 fail me yet. But I did burn one up during a short circuit crash. As well as all the other servo's and stuff. Smoke and fire and all!!! Should have grabbed the video cam and set some small toy people around it. LOL! You will love the CopterX if you ever get it. Maintenance is key to all these birds and watching bearings in the Blade holders on the rotor as well as all bearings is a must. You are probably aware of these things so I won't go into a lecture. LOL! HAPPY FLYING!!

Well I will try and help but the instruction are not that clear O.K First move your throttle stick to top on Tx(wide open)then turn it on,plug in your esc,(make sure your motor is plugged in & secured or you wont hear the tones)you should hear a special tune? then beep beep beep to let you know it is in programing mode Norrad you know it is going to take along time to list this i will just try an post the instructions If i cant ill re-type it for you

If this thing is advertised as a heli ESC it needs to have a BEC that is capable of handling common heli servos like the hxt900 servo with draws roughly 500mah. 500mah times four servos means you need at least 2 amps minimum. If this is a 2A esc then it needs to be advertised as such. Even still, you're cutting it close with 4 servos/gyro required on a 450 sized heli. I ordered one based on the fact that I liked the heatsink and it said designed for heli's. I'll post my findings with 3 HXT 900's and an hs 81 on the tail when I get everything. Max what servos do you have on the HK450?

Ok got it hooked up on my Trex 450 with 3 hitec hs-65's, futaba gy401 and Futaba 9650 tail servo (instead of my ohter heli seup with hxt's and 81. The 2A BEC ran everything fine (no brown outs) doing heavy collective pumps, flips and piros. I'm impressed, for only 10$ US its a great deal. Sends plenty of juice to 4400kv motor (11T pinion). Runs cool but it is winter so not hot days yet.

Anybody know how to set the throttle range on this thing? I have one that is on an HK450 and it works great. Stting up another HK450 and on this one, motor does not start until I move the stick to more than 1/2 way up!!!!Ths instructions say "imortant that you set the throttle range on new radio..." but then they sae "see page 4", when you go to what I think is "page 4" (because all I got with the ESC was one page double sided)It just goes on again about how to program the ESC BUT NO INSTRUCIONS ON HOW TO RESET THE THROTTLE RANGE. Anybody done this yet? How do you do it??Cheers,Max from Aurora

When it says that you have to rest the throttle range, it means on your transmitter. For example. My futaba 9C has end points that default to 100/100 for each direction of travel for each channel. I leave it at that for all of my servos except channel 3 which is my throttle which is actually set at 140/76. Why is is set that way? Because you start your throttle end point at the bottom (zero in this case) with the stick all the way to the bottom. Make sure your esc is plugged in and then you gradually increase the bottom end point number until you hear the esc engage. Thats how you get the bottom number. Then I maxed out the top number to make sure I got all of the esc's power available. Your bottom number (end point) is probably set at 100 so your esc is not engaging until 1/2 stick. Try lowering your low number, or dropping your ATV down if you don't have a computer radio. Hope this helps!

You do this by setting the throttle to MAX wait for the melody and double beep. Then set the throttle to MIN. You are ready to roll now. Mine will not remember the range and have to set it each time I change the battery

The Manual which comes with the ESC is a partial copy of the one presented in: ***********fmadirect****/support_docs/item_1268.pdf -Except that this indeed have a "Page 4" which explains the procedure. Take a look at this manual because it is clearer and says the same as the included one. Basically the procedure is the one explained by snappy.

If you try it and the servos cut out, or the esc resets then you may need to get an external 3 amp BEC sold here on hobbycity for less than 10 dollars. I am in the same boat waiting on this ESC to come in and have 2 HXT900s and hs 81 that need to be powered by it. I'll post if it works or not.

This isn't speed controler related, but I think the HK450 will do better with a faster servo on the tail rotor. Much as I like the hxt900 as a general purpose servo, I think it's really too slow for the tail rotor, at least if you're using a heading hold gyro. With a rate command gyro, it's probably okay. Barely.
To address the bec problem, you can always add a ubec. They're $8, 8gms, deliver 3 amps, and insure you can at least maintain some control if your controler fails in flight. Also, ubec's usually use a switching circuit (SC bec's are typically linear), so they actually draw less current, generate less heat, AND the heat is not generated at you SC. I should add that you should only buy a switching ubec, just no point in paying the $ and weight penalty to get a linear circuit.

Hi
I have the same problem.
I bought tree, and only one accepted the programing. About the others two, one didn't work at all, and the other didn't accepted the programe (both, card or radio).
If one works properly and the other don't aceppt the program can be a problem of factory.
I am going to send back this controller and hopping an answer by hobbycity.

This ESC is dedicated to Heli but I can not set it up onto soft or supersoft start. I have tried many times but still can not carry out. It is not the case of programming- I have changed brake mode, timing, reset to factory settings vut soft starf is not available. does anybody faced with the similar issue? Has anyone got any idea how to solve it?
Thanks for your tips.

I have set mine up with a Turnigy programming card and it works fine. So I am not sure what your problem is. Did you use card? Did you use the beeps? I have used the beeps too but the card makes it almost fool-proof (which I seem to need a lot lately). :)

Hi,
I don't have a programing box, so I have to do with the "beeps". As it came with no instructions, I could not change anything, but it worked fine in the original configuration. After a few flights, something went wrong with the receiver and the ESC started to beep non stop as soon as it was plugged. I have found the manual on a different forum and everything is ok now.

It looks like I have expected too much from this ESC. It was set up properly from the beeps - I have checked it with the TURNIGY card. Both beeps and card programming give the same results.
The point is the super soft start is very close to normal - if normal starts instantly, super soft takes less then 1 sec longer. I have expected it would take at least 2 sec - as well known branded ones. for less then 10$ it is hard to expect so.

Jacques, try setting throttle to full then plugging in battery. After it beeps, set throttle to bottom. Unplug battery. Keeping throttle at lowest setting, Plug in Battery. If you keep getting beeps, try setting your throttle sub-trim down till it stops. Hope this helps.

Im using it in two 450 class Helicopters and they have been working fine and cool for a month. I use a 3800Kv Motor, DS480 tail servo, G401b tail servo, and three Hextronic MG-14 cyclic servos. Installed a 5 amp BEC for extra precaution so if the ESC does go out I can kind of control the heli for hard landing. Not problems yet though.

Yes the hobby wing program card works great with this, right down to picking a tune to play. The hobby wing program card looks just like the Turnigy program card so it should work too.
Looks like it has governor mode and I could turn it on and off, but I have no idea how to use Governor or what the advantage is.

Excellen ESC for the HK450.
Tighten/loosen the screws to have all fet's touch the heatsink. Bec has it's own heatsink. Gets barely warm in my 2 hk450's, where the Supersimple 25A got really hot. Soft-start is good.
I do use ubec in one hk450, none in the other. bec is solid.
