HXT 63-74 200kv Brushless Outrunner? They have them now as I just received one in the mail.

Does anyone have any idea as to the Max amps this motor will handle. I have written to United hobbies but their e-mails are down because of an earthquake. Their site has very little info concerning the tech side of this motor. Can someone enlighten me?

[Madmax1965]

Seems United hobbies list this motor as 200kv while the sticker on the motor says it is a 280 kv. Anyone know for sure what the kv is?

[Madmax1965]

United said(in an e-mail) that some of the HXT 63-74 motors are indeed 280 kv.

Hello,
My stepson and I have converted a Hanger 9 ultra stick and a Great Planes PT19 with the HXT 63-64-280 motor I bet that the max amps are similar to the -74. I believe the max amps would be around 65 Amps. You can see the set up at the begining of the video.
We used 8S with a 16x8 apc e prop at 1500 watts around 45 amps 7500 rpm.

12lbs of static thrust and the draggy stick level flew about 60 mph.

The ustick AUW was about 8lbs, and the PT19 was 12lbs. We converted both of these planes from a OS 91FS glow. This electric setup has much more power. It makes us laugh because it is like having a new plane with the new power!

Click the link below for the stick video. These big motors seem to be good. I had to retap one othe the mount holes in the motor, but other than that it works great.

Nope. Stock status is still -2. https://www.unitedhobbies.com/UNITEDHOBBIES/store/comersus_listCategoriesAndProducts.asp?idCategory= 63&curPage=4

Are you sure you have the 63-74 200kv rather than the 63-64 280kv motor?

Cheers,

[Madmax1965]

The motor is suppose to be a 63-74 200kv but a sticker on the motor says it is a 63-64 280kv. I wrote an e-mail to United Hobbies concerning the matter.

Here is their e-mail to me:

Hello.
The factory often change Kv on us without notice.
The sticker indicates the tested Kv for that batch, the factory told us there would be a variance of around 10%, though we are seeing variations a little higher than that.
If the motor does not suit your requirements, you can send it back for a refund or change to another motor, we will refund the postage.

FYI.
We now check each and every motor from that factory, as this issue has caught us a few times.

There you go. You've got the shorter 63-64 motor, rather than the 63-74 motor. Measure the length of the motor from the mounting face to the rear end of the shaft. The 63-64 is 64mm long, the 63-74 is 74mm long.

Another thing, though I wouldn't rely 100% on this. The 63-64 has blue anodising while the 63-74 has gold anodising. At least in the photos on the website.

[Madmax1965]

Redryer I made a mistake in describing the motor I received. In the post above I said:
"The motor is suppose to be a 63-74 200kv but a sticker on the motor says it is a 63-64 280kv. " What I meant to say is that the sticker says the motor is a 63-74 280kv rather than a 200kv.

My motor is Gold and the measurement is 74mm...but a sticker on the motor says it is a 280kv......United says some of the motors could be 280kv.

At any rate the motor is fine as it is...suits my plane o.k. and from what I can tell I have a gold 63-74 280kv motor.

[redryder]

No worries. I thought they had maybe sent you the wrong motor by mistake. Interesting that they have changed the KV. I'll have to query united before I order mine as I am really after the 200kv. :)

Cheers,

[redryder]

How about it, CSO#1@UHobbies?? When will the 63-74-200kv motor be back in stock? And will it be 200kv or 280kv like the motor Madmax1965 has recently received?

Maybe you are still being knocked around by the internet problems after the earthquake. Maybe not, as you you have posted several times in the last few days.

Im unclear on who is who and what the order was.
We have a 63-64-280 and a 63-74-200
Possibly, you got a 64, or a 74 with a 280 sticker.
I am really just guessing here, please email us for clarity.

No emails. Let's just post it out here for everyone to see. :)

What I am after is the HXT 63-74-200kv motor as listed on your website. As of right now, the stock status is -2. I take this to mean you have two on backorder. Is the HXT 63-74-200kv in the delivery you are expecting from the factory on Monday? If so, are there enough to supply the backorders and new orders? And will they be a 200kv motor or a 280kv motor?

Cheers,

[Madmax1965]

Already e-mailed you....problem taken care of....However I still don't know if I have a (gold)63-74-200kv or a (gold)63-74-280kv. Main thing is the motor flies the plane just fine.

[redryder]

Still, United Hobbies has not answered my original question. :( :(

This is the United Hobbies forum, isn't it?

When will the HXT 64-74-200kv motor be back in stock? I don't think that is a hard question. :confused:

"Factory order is arriving on Monday.

Anyway,I ordered the same motor but the KV listed is 200 and I want the 280 version .I PM'd CSO#1 and also EM'd United 2 days ago to make sure they ship the 280KV one but have not heard back since.They have been real busy and slowly upgrading their site and operation,so I'll try to be patient. ;)

[8kasl]

Still no word from CSO#1.I've been patient so far but patience is wearing thin now.It's bad enough to have to wait for close to a Mo. to get your order in the States,but not knowing if it will be what you wanted is not acceptable.

I have two of the hxt 63-74 200 motors on the way. Will let you know what sticker is on the motor.

Jim,Which version did you want,the 200 or 280KV?They(united) said over a wk. ago that they would post both versions on their site and as of yet they have not.I EMd them and also PMd about 4 days ago and haven't heard a word yet about the fact that I wanted to make sure they send the 280kv version.I'd hate to get the 200 as I would have to run more cells than I care to--big cost increase factor to me.I guess the waiting and wondering is part of the price we have to pay for slow service response and shipping.Maby customs keeps our orders for a couple of wks.,I just don't know.

I'm wanting the 200 kv because I already have a 10s pack I plan to use with it. If it is the 280kv that comes, I'll use the 10s pack anyway and will watch the amps. Should be here tomorrow or Saturday. James

I plan on using the 63-74 200kv on the Hangar 9 P-47 81" wingspan.
I estimate at most it should weigh about 17lbs.

I have a few other planes with larger wingspans 90" etc.. but they will probably come in a little lighter so I will use the 63-64 motors on them.

I see they added a new 63-64 motor to their stock in addition to the one that is 280 kv.
The new one is 230 kv. (It says 280 kv in part of the title but that is incorrect, it is 230 kv)
Here:
https://www.unitedhobbies.com/UNITEDHOBBIES/store/comersus_viewItem.asp?idproduct=4188
and the previous 280 kv one here.
https://www.unitedhobbies.com/UNITEDHOBBIES/store/comersus_viewItem.asp?idproduct=2097

The new 63-64 230kv motor lists its maximum watts output to be 2592.

Sounds like the 63-74 then, would be more than enough. Probably even overkill. That's ok maybe I'll try to hover the P47. :)

[8kasl]

Jim,Maby you could compete in 3D with the P47 LOL!!!The flight reports are startimg to come in on this little motor and all seem positive!Just wondering if the HexTronics controller(HV) is reliable.I guess only time will tell.Wow,2592W would fly a 50 lb. Cub!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!
Rich

[JIMinKENTUCKY]

I checked the instructions included with the HXT 63-74 200kv and it lists the watts output to be 2880.

I hope someone gets some measurements soon to see if they get close to that. Its going to be a while before I am able to test mine.
I have been in the process of moving and everything is still boxed up.

[8kasl]

Jim,That's almost 3KW!!!!WOW.How's the weather in Kentucky right now?It's rather unusual here in Colorado---warmer than usual and very little snow.Check out the "Magnetic Pole Shift"---may have something to do with it.Anyway,can't wait for Spring so we can start testing these puppies out in real world!
I wonder what's next in the outrunner world---a 95-105?
Rich

[JIMinKENTUCKY]

Rich, glad you are having warmer than normal temps in Colorado.
It has been mild in Kentucky too so some of my family tells me. I am living in south west Georgia now so weather has not really been a problem. My niece and nephew went swimming about a week ago. :)

I suppose I need to change my username to JIMinGEORGIA now. :)

One good thing is I am only about 1.5 hours from the South East flight festival in Americus, GA

Concerning the 63-74 motor,
on the UH description it gives the
recommended model weight to be between 6,000 to 10,000 grams.

But in specs included with motor it says the motors actual "pull" which I read as thrust is in the range of 6,000 to 10,000 grams.

That's 13 to 22 lbs of thrust, so model weight could be much heavier.

Anyway, could be some things lost in translation so nothing matters until real world tests.

You have a PM.

I´m using the HXT 63-74 with a lanyu 24x8 prop, and Sentilon 80A 2-12S High Voltage BESC, with 4 x HXT D9 2200 mA arranged as 10s2p on a 25% CAP 232. I tell you THIS I A MONSTER, with full throttle it runs 10 feet then goes straight into the sky and continous at full speed, the model weight is around 13lb.

[pdemon]

Borlax,
have you measured the ampere?
Pierluigi

[Borlax]

I have not not measured the amperage yet, that will come when i borrow some measuring equipment, it´s all put together on a estimated guess. But maybe it´s a bit overkill for this airplane. I can tell you, the ESC only gets hand warm on hard use for 10 min. on this airplane.

[Borlax]

Just for your information, the HXT motors are sold under different names. The factory is XYH Motors.

[pdemon]

thank you for the link. Have you a picture of your motor mount? I'm planning to install this motor in a CMP 80" Zero, so any suggestion will be very wellcome. Have you find an use for that alluminium collar included in the mounting package that comes with the motor? The instruction are scarce to made a compliment :confused:
Regards
Pierluigi

[Borlax]

I made the motor mounts from aluminium with rubber dampers in between, this gives a nice a quiet running.

[Borlax]

I removed the cowl and took some more pictures for your convenience. on Pic1 you can see the very short leads from ESC to motor. On pic2 the batteries are installed. On pic3 it shows the reciever battery HXT D9 2s lipo with HXT 6 Ampere BEC. I have set the jumper on teh BEC to 6v, to the servos are very powerfull and quick.

[pdemon]

Borlax
nice work indeed! The pics are a great help, the hinged battery retainer is a clever touch... Are you using digital servos? I was thinking about an RX battery backup system, with all that investment in money and work, it seems sensate to me.
Thank you
Pierluigi

[Borlax]

I am using the MG995 digital servos, very reliable and powerfull, and extremely fast on 6V. I am a bit annoyed about the big cutout in the bottom of the cowl, but it´s the only way i can change the batteries fast, on the other hand it gives lot of cooling to batteries , motor, and the ESC.

[Borlax]

I have bought a clamp on Amp. meter and the motor use 10s2p cell packs. I have measured 42v. 64A. at 6100 rpm. with a 24x8 Bolly. that is 2688 watt that is close to the claimed output of 2,8Kw

What kind of cells are those? A 10s pack that puts out 42 volts with a 64 amp load? That's zero sag and zero internal resistance ;)

I'd guess your voltage under a 64amp load would drop to at least 37 volts, probably more like 34 volts. I'd bet you're not pulling much more than 2200 watts.

I have the same motor and have a 22x12 on it. Haven't spun mine up with a prop load yet, but I'm beginning to think that at least 11s, possibly 12s might be needed to bring this motor to it's full potential.

This is HXT D9 2200mA 5s packs x4 arranged as 10s2p as you can see on the picture above. Mind you these cells are able to deliver 35C in 60 sec. that´s 144A !!!. i have not monitored the voltage drop yet, but i was out flying today, really punishing the model, and it seems that it retains the same rpm. for 6-7 min. at WOT. This CAP 232 weighs about 13lb. i can hover in mid air at about 1/3 to half throttle, when i give it WOT it takes of like a space shuttle. I am very pleased with this HXT gear from United hobbies. Considering that motor, ESC, and 4 battery packs cost only 374$ that´s a lot of power for the dollar.

[Greg_Granville]

35C ??? So, you're saying these 2200 cells can deliver 77 amps? I got four packs of the 20-30C 2200 LiPo's from UH last fall and agree they are great batteries for the price.
However, I strongly suspect that if you tried to pull 77 amps from an HXT2200 pack for 60 seconds, you'd see some fireworks before the clock ran out ;)

Anyway - glad to hear the motor is working out so well in a 13 lbs model. I am planning to install my HXT 63-74 in an 80" Katana which should come in around the same weight or slightly more (~ 14lbs).

[Borlax]

Well Granny i admit i´m a bit overenthusiastic about the the Amp and voltage on the HXT cells. But i tried my motor with 10s1p and it also draw 64Amp but the voltage sank to 34v, but it did fly the model around for 4 min. though. Thats pretty hard for those small cells, would you believe granny !?!?!?.

[Greg_Granville]

Hmmm, well. I can pull 50 amps from mine for 8-10 seconds bursts and still remain above 3.3 volts/cell. After that, they need time to recover.
They don't deliver current like this when cold. Then need to be warmed up first.
Perhaps the formulation has improved even more recently. 50 amps is 23c - which I am quite happy with for "bursts". But 35c is simply amazing... even if it's only a short burst.

Any chance of seeing a video of the CAP in flight? That would be cool.

[Borlax]

i ususally visit the UH website 2-3 times a week, to see if there is any new products. In late March, i saw that the HXT d9 cells was upgraded from 30 to 35c. I was in now, but there was nothing mentioned about it ?. I´l try to make a video of the plane in flight this weekend, and post it here.

[thejekyll]

Borlax,
I have an HXT 63-74 and a Sentilon 80A 2-12S High Voltage BESC. I'm going to install it in my 80" Hangar 9 Cap 232G. I did a search on the net to find if someone had a setup for this for this motor combo. I came across this forum and read your post about your setup. Nice plane. I have a couple of questions. Did you program your speed controller or just run the default setup? Do you think running a smaller prop like a 23x8 would keep the amp down and still be enough to have a good flight?

[Borlax]

I did program the ESC so that brake is OFF, if not you risk the prop loing loose. Start mode VERY SOFT on such a large prop. Timing mode to HIGH beacause the motor has 14 poles. And last, number of lipo cells. I my opinion all these settings are very important, cut of voltage is more a question of temperament. You can go down to 18x12 prop and this have plenty of power, maybe not for 3d but it will certainly fly the model around, and you will use around 40-50A. if you use 10 lipo cells.

[thejekyll]

Thanks for the info. You really think a 18 x12 will be enough prop. I was thinking 20 x 11, But just a guess to start with. My Cap should weight in about 15-16Ibs. I'm going to SEFF 07 at the end of the week. Is any one here going? Will, when I get back I will put this setup in my Cap and let you know how it worked.

[Borlax]

I once used a 18x12 and i was adequate for flying, but didnt give much thrust. The funny thing is the top rpm is the same with 18x12 up to 22x12. But there´s a lot of difference in thrust. and of course Ampere.

[Greg_Granville]

Update on this motor. I have it installed in a Seagull Bling 3D and the power is phenomenal. However, the stated kv of 200 seems to be off, I believe it is somewhat lower than that based on my experience. I should have been able to run it on 10s and a 22x10 prop and gotten 2000+ watts. Unfortunately it was more like 1400 watts. Way short of what is needed for a 50cc class 3D plane. :(

The 2 - 5s packs of Hextronik 4100 D9's had puffed up like a dead fish (never even got to fly the plane with them) , so I decided to build up a 12s pack of 4000mah HECELL's. Now it rocks. With the ESC set to high timing, it pulls 2800+ watts static. On medium timing, it pulls ~2500 watts. I have decided to leave it at medium timing because 2880 watts is the maximum rating of the motor and 2500 watts actually gives me PLENTY of power.

The motor does seem to get hot pretty quick when run at high power levels. I don't think it's hot enough to cause a problem, but I am a little surprised because I have several other fairly large HXT motors (50-65 and 42-50), that run very cool.

I can't quite figure out why the webpage for this motor recommends 8s as the max. That's just to low a voltage for this motor. You'd have to put on a huge prop and really lug motor at low RPM's and sky-high amps. It seems to be much better suited for running on 12s.

[CarreraGTSCS]

Greg-- Where did you get the Hecells? I like to build my own packs.

Thanks,
Mike

[Greg_Granville]

Mike,

I bought them from eBay seller 'qlty4s2u'. He doesn't have them all the time - you have to keep watching. He sells the individual cells with bare copper tabs for an opening price of $19.75 each. I was able to get 12 cells in two separate auctions for that price with a little patience. He also sells the cells with wires attached for about a buck more. Don't see any point in that, but if you're desperate you could buy them and remove the wires.
The big problem I've had with qlty4s2u is that he is very slow at shipping. It took a week or more (on both auctions) before he finally replied to my emails and actually shipped them. Once shipped, everything was fine.
These are excellent cells - too bad this guy is so slow at shipping.
There is another ebay seller - 'real157' - that sells HECELL pre-made packs, but no individual cells. His prices are a bit higher, but he seems to have an exceptional feedback rating. I might have bought from him, but he never seems to offer any large 4000mah packs.

[CarreraGTSCS]

Thanks Greg. I'll get some Hecells. I need to make 5s and 6s packs for an upcoming project. How many cycles do you have on your packs?

Mike
