Yes, I do! If you "GOOGLE" this item, you will see Hobby City also markets this product. BE CAREFUL!!! I for one have not had a very good experience with them. I'm sure I am
not the only one who got burned on an electric outrunner motor ie_ Turnigy: TGY Aerodrivexp SK Series 63-64 230 kv/3150w. You can read all about my experience in a thread
here in the pattern section. Again, EXERCISE CAUTION! This operation does not have a plan to handle any type of Warranty issues. In other words, " it's your puppy when you buy it" unlike some of the other reputable hobby shops you've done business with in the past. Hobby City is aware that I will always be more than happy, now & in the future, to step up & "sing their praises". Regards____TN WALKER

TNWalker you are wrong, look at the specs on Megamotors.cz ( http://www.megamotor.cz/v3/script/de...ge_id=lang_eng ), and you will realise that the ACn F3A is an inrunner, and has nothing to do with the Turnigy outrunner.

Kjeld, Please read my first sentence! This motor, the MEGA ACn F3A, was mentioned in a write up that was "Googled" & it mentioned it's availabilty from Hobby City. I know it's cold in Denmark but please don't read into my response. I merely went on to "slam" the Turnigy motor because my plan is to take every opportunity now & in the future to let as many pattern flyers know the REAL Hobby City. I think you have more of a problem pointing out what you percieve to be an error than the act itself! Perhaps you fit into the group
of people I mentioned in the "Turnigy thread" above_ie, "running around & jumping to conclusions!" Is this your form of physical therapy or just a good way to stay warm? Regards________TNWalker

TNwalker, what're you on?? COKE or something like it.

MEGAmotor HAS nothing to do with HOBBYcity or TURNIGY.

Pictures shows the MEGA ACn F3A motor that will be used in a Krill SPARK.

Prop PT 22x12 Amps 57

Don't take notice of mr. SMART ASS TNwalker, he don't know what he is talking about.

"running around & jumping to conclusions!"

People in glass houses should not throw stones.
This thread was started by a guy ,new to here, with a genuine question.It should receive the courtesy it deserves.
You have had some bad luck/service ( a few hundred bucks worth ).Get over it .I for one have seen enough of it here.
To be fair to the guys your response can read as being negative to this motor,they may not have read of all your woes.
So please don't jump in on every thread that mentions an E motor,as the threads loose direction easily enough anyway.

Brian, thanks for your response. After seeing this motor mentioned in a thread from Hobby City I ran across several days ago, I could only assume they were marketing this
particular motor. If you "Google " this motor, perhaps you will find the same info. BBpattern, please accept my apology. You are not aware of the bad situation I find myself in with Hobby City. From what I can gather (specs) about this inrunner motor/MEGA ACn f3A, it could very well be just as good as any of the other inrunners available to us at this time or even possibly better! You Joen, I choose to disregard any & all that you have to say! Your use of the English language is pathetic! Regards_________TNWalker

TN,

You can be as mad as a mad dog at the way things went. You could swear, curse the fates, but when it comes to the end, you have to let go.

TN

Please, if you have personal problems with a supplier, take it with the supplier and not all of us.

I don't know you, but have read every word you have written and must say you need some firm spanking, and you IP banned forever.
people like you should be put on an island far far away without electricity-modelplanes and computers.

May your ass be itchi and your arms to short.

P.S.

Will post results after I have maiden my KRILL SPARK.

OhD, your are absolutely correct & that is what I am in the process of doing. I suppose I was very diappointed & could not believe this could happen. But, you know, it can & does happen to each & every one of us, sooner or later! So, with your guidance, my plan is to leave all of this behind, here & now. Also, Joenella, I'm looking forward to reading about
the maiden flight of your KRILL SPARK! Regards__________TNWalker

I don't want to take credit for the words as they came from Benjamin Button but they do make sense. Also be very tolerant of our friends from across the seas who are trying to share our passion. English is a difficult language. For example, the difference between your and you're.

OhD/Jim since my last response, Hobby City has decided to take the problematic Turnigy motor (TGY Aerodrivexp SK Series 63-64 230kv 3150w) back for credit. It seems I'm not the only flyer out here with a problem! At least they were willing to listen & take corrective action. Thanks again for your support & imput. Regards_____________TNWalker

So,

How about if we get the thread back on topic? the original question was if anyone had experience with the motor. Joenella was kind enough to post some pictures of it. Do we have any more information on this? I went to the website and there's a good pic of it. I like the prop shaft arrangement. They state 850 RPM/min/1V 170 RPM/min/1V behind gearbox. I am not sure how that compares with the stated 1300 RPM/V listed for the Neu F3A-1 and 1249 RPM/V listed for the hacker c50-13xl. It seems low if it is 850 vs 1300 or 1249, so the 5:1 gearbox ratio is probably about right for this motor. Using these posted figures, the numbers behind the gearbox would be 170 rpm/v for this, 194 rpm/v for Neu and 186 for Hacker. The 60A max current rating seems light however.

I agree. My first thought was the same. We are looking for numbers around 230 for the outrunners. I haven't looked close but maybe this is designed for 12S packs? That would also account for the lower max current. The combination of Kv=170 and 60 Amps won't work in a 10S, 5 kg pattern plane. Is the max power specified? We need about 3KW and that would be 50V at 60A. 14 cells?

Steve, I can't make Lancaster on Saturday, but I'll probably come out on Sunday if the weather is good, so I can bring you some grease if you still need it.

Glad you got a positive outcome.
If you are still looking at options the Pletty 30 10 Evo can not be beaten.
It is the most powerful motor under 600g, is very high quality and has no gearbox maintenance.It's ultra reliable,so much so it's probably the best value for money when all is said and done.We have two with 400+ flights and one with 600+ flights and they are all still as new with no servicing at all.
It's best point for me is it's sound in the air. Its sweeeeet.

Brian

Well it seems low in rating, but however, I have been using a AXI 5330 with a 20x13 AXI prop which have a consumption of 67A @10S, the SPARK is rated to be used with around 2kW so the 57A @10S seems fair enough.
Be aware that this motor have a 5:1 gearbox giving you 170kv on the shaft, that's why they recommend prop's in the high region as 22x12.
I have flown the KRILL SPARK now from the beginning of it release I even have a prototype version of it and IT IS NOT designed for high speed, try have a look at KRILL's webpage and you will notice that the motors recommed ALL is in the 170kv range and NOT the useual 230kv , it is very very stable in high wind even with low speed. But off course I'm a bit nervous if the MEGA have enough power, I might go for a even bigger prop as a 23x12 or 22x14 only time will show.

Joen

I agree that the motor seems to be built for a larger lower RPM setup versus the smaller higher pitch. i dealt with this in a Dualsky motor which I am still running, I got good performance out of a 20X15 but noticed areas where the setup was lacking the power I wanted. I narrowed this down to the motor loading up on uplines and unable to maintain pulling power. Going to the larger 22X12 allows the motor to work properly in its power curve.

Good luck with the motor, if you are a pilot who flys at a slower pace than most, you will do just fine, and be patient in the wind.

Chuck

Thanks Jim,
I still plan on going to Lancaster. I've got some work/testing to do on the setup tomorrow so hopefully I will be ready to go.

You'd better be there!! I wanna fly that Passport!! LOL

I am also interested in learning more about this motor Steve. You should buy one, and let us know!!

C

I must say one thing here now.

I have got two post deleted by ????? someone for bashing, I think those ??? should look carefully on ALL post in this thread and maybe delete mr TNwalkers post as well, or is it OK to bash some high quality manufacture?? .

I must say, I don't like you way of censor, it is a free world we are living in with the freedom to speech freely or is only for you US citizen??

D... H....

Well well moderator,

In plane english, you're a dick head,

Afraid for deleting mr TNwalkers bashing, but my post is no problem, get serious!!!!

Please delete me from this webpage, it can't be used for anything good.

Sorry guys no repports from my side regarding the Mega motor, but it is very very good that's all

Bye bye

I suspect that the reason our posts were deleted is because the post we responded to was deleted. I don't think it had anything to do about what we said.

Jim O

Well

I have now more than 150 flights on my ACn F3A motor, and it is behaving nicely.

It have a nice smooth power curve, lots of power, best prop for it in my finding is PT21x14E, where I fly whats your advance program, and using in the area of 26-2700 mAh.

No heating problem, noise non excisting, it have a bit different sound than the Hacker have, but sweet sound.

Grease it every 50-60 flights with MOBILGREASE 28 and you will have no problem.

Currently I'm in second spot in the Danish nationals, so I can only recommend this motor.

Ohh forgot, I'm using YGE80HV speed controller

joenella , i am interrested with the ACn F3A motor .. . . how would i order one ?? and how much does it cost ??
