Hurricane 550 is here, cheap, light and flies just awsome!

[Tom Viper]

Ok, I better start with this...

http://www.ezfly.se/Files/hurricane.jpg
I´m the one on the pic that dosen´t speak Mandarin :rolleyes:

And...

http://www.ezfly.se/hurricane_studio1.jpg

And this...

http://www.ezfly.se/hurricane_studio2_chassie.jpg
All push-pull, alu-swash and BB.

And this too...

http://www.ezfly.se/Hurricane_box.jpg
Open the box, add servos, go fly!

Ok, now you all seen it for the first time :D

Its the Hurricane 550, a new heli that it just about the best new electric heli I have seen and flown for a while. Why´s that? Beacause:

It uses 6S1P, or acctually 2 pcs 3S1P, so your TREX XL batteries works fine!
It comes ARF, with 500mm blades, painted canopy and all bearings/thrust bearings you can think of.
It comes complete with brushless motor (KV800, 1000W) and ESC 50A Gov, 6S and a BEC that works!
It will NOT break the bank!
All weight is centerd, so TP is on the boom, and shaft! Guess how this one rolls? Thats right, straight as an arrow!

http://www.ezfly.se/Files/hurricane_accar.jpg

And know ladies and gentlemans...The AUW is 1,95KG. Thats right, read that again to be sure :D My own acctualy went under this, 1.89KG with 2x3S 2250mA 20C packs, 401/S9254 servo, and S3151 on cyclic, JR 770S mini SPCM RX, stock motor/esc/bec and everything else.

It can easly take 550 blades, pinions for this is in the box.

Do I like it? H_ll Yeah! So know you wonder what the price is? Let me say, it will compete with the TREX...450!. Parts? will make you smile.

I have been very very lucky to get these helis.

Did I say that it comes with alu swash and hub as standard? And that it has a driven tail?

Christmas came very early this year...

Sorry for being so hyped, but this is what I have been waiting on for so long!
A nice designed electric heli, that has good quality without forcing me to take a second mortage :)

Looks cool but why don't they ever take into account battery placement when building electric helis? People like to slide batterys in......

Yes offcourse, but then the TP weight gets lower aswell. I rather go with this design, All weight is centerd, so TP is on the boom, and shaft.

Also the canopy (which is 60g painted) is very easy to remove. And it´s not flimsy or weak. I hated my Swift, beacause the canopy was a small h_ll to get on and off. Then, offcourse you can use welcro tape, instead as in the pictures ziptie's.

[GGoodrum]

Actually, other than the pack placement issue, there's a lot to like about this design. I like that the motor is up high, and the push-pull linkage looks solid. It is definitely going to have a wicked roll rate. :D

The two-stage gearing could provide some better gearing options. Do you know what pitch it is? It looks like mod. 1.0, but it is hard to tell.

If it could be mad to fit, I would think a single 10-cell a123 pack and something like a Z30A-800 would be a great hard 3D power option for this, especially since it is so light. Might need a metal hub upgrade, though, but maybe not.

Interesting. Looking forward to seeing more of this. :)

-- Gary

[Tom Viper]

Oh, metal hub and swashplate is offcourse stock :D

http://www.ezfly.se/Hurricane_head.jpg

One more thing, look at the installation, it is impossible to get it ugly!
All servo cables goes inside of the chassie. And the RX is far from anyting disturbing :rolleyes:

[ozace]

Great find Tom.
Looks like the 500 size is going to hot up with this and the new trex 500 comming.

[rerazor]

I agree about roll rate but battery placement should be designed for a more universal fit. I just hate having to hang batterys etc... Looks like a really cool heli and the design looks nice also. Should be popular if of high quality and low cost.

[eMeNeX]

If they drop the battery tray down a little bit you could put a 6S on that tray. I give it a few months before someone designs a new frame for it.

[ARCHER7153]

This is too good to be true. Is the price under $300

[rerazor]

If they drop the battery tray down a little bit you could put a 6S on that tray. I give it a few months before someone designs a new frame for it.

My point exactly!!! Why not design it that way in the first place?

[Tom Viper]

The point is to have it all centerd, just like the Synergy for example, it has the motor higher up in the chassie, as all electrics, just for that same reason.
Second, the whole idea is to use 2x 3S packs, to bring costs down. If you want all the weight down low, I guess this is not what you are looking for ;)

Could you please tell me the benefits of having the packs down low in the chassie? Except for changing the packs? 99% of the times, you need to take of the canopy anyway to change packs right?

[rerazor]

I totally agree that for best flight performance you want it all it centered and the Hurricane looks like it has that it its design. Not knocking the Heli.

[Larren]

Hi,

Any link to the manufacturer's website?

Thanks.

[chinlin0924]

It must have design consideration that we don't know.(Lower CG)
Battery location is not so important to me, as we don't alwayse fly it to crash it.
With canopy protection and belt fasten, it is not that weak.

[eMeNeX]

I'm not saying anything is wrong with the design I think it's an awesome looking heli with great potential. That video of it doing 3D looked pretty baddass. I'd consider getting one depending on cost that is. Although I have a lot of heli projects on my plate and no time =/ How about 3S1P 4000Mah packs would they throw the CG off at all?

[chinlin0924]

I don't know, but I might get one this week to see how good it is.
I got a heli flu. :P

[n1troboy]

looks interesting

[chinlin0924]

So what are they called and who makes them ?
GAUI Technology. there is no website of this R.D design company.
They don't sell products.
As I know, RCmart might be a big source. You could ask them if you are interested. http://www.rcmart.com.tw

hope that helps.

It is called Hurricane 550. And it has not been released yet but I have some of these allready (in Sweden :) ), so if anyone is interested, give me a PM.

[Tim Tompkins]

Consider the possiblity of crashing and only damaging one of the packs. I can see this as a good way to buy a few packs and rotate them. I also see this as a good way to move up from a t-rex. I have several packs and I don't worry about charging at the field, I just plug another one in and go again. I have others but I like the look and size. It sure beats the cost of others in this class. It comes very well fitted, aluminum swash plate and head hub. Room for servos ect. I like it! TimT

[Impact]

Is there a price for this heli? Is there a kit? Who will be selling this heli? I would like to see a parts price list to compair against a logo 10 and a swift......Impact

[misskimo]

yeh ! I think they could have done better , batteries way up front like that , just tells me , dont crash the heli , side mounts are better pretected , or inside the frames, roll rates , it might help a little better , but a consitent roll done with the right amount collective swaping will produce a good roll , its all about how you do it . my Ion , no problem , my old Joker with all the batteries on the bottom , no problem ,

Tony

[Tom Viper]

To use two packs, in the event of a crash there is very little possibilities that you destroy them both. And as you said, if you have a trex, you allready have the packs! And 3S packs are cheap, and easy to maintain.

I just put mine on the scale, and AUW is 1846g! So it is even lighter then the supposed 1950g. I am using all stock ESC (which has a wonderfull soft start), Futaba 401/S9254 and Futaba S3151 on cyclic. This is with the 6S1P (2 x 3S1P) 2400mA LiPo´s. It comes with three pinions, 14T,15T and 16T, i use the 15T and get a HS of 1940. Its nice to fly light that and then dial down to 1550 rpm and just cruise around. I am amazed on how fast the pitch is, even at low rpm, but I guess its the low weight that matter here.

After a 8 minute flight (breaking in the new packs) the motor is warm about 48-50C, and the esc is 41C. This is in 11C outside temp. I have the Z-motors 30 size, but dosen't feel there is any idea to shift, the stock motor works perfect. I hope you get this heli in the US soon.

[tungym]

I am building one now.....the package includes ESCand 800kv BL.

Nice, i´m sure you gonna like it! Its the best thing since.. well, the logo 10 came out.
I have had alot of helis, concept ep,trex 450,x,se,scf,600, zoom400,ep100, swift, logo 10, logo 14, 3st e-raptor conv, rebell, quick EP10, ep16, and then some... Some are good, and some not. This is one of the best up to date. Have fun ,post some more vids and what you think about it when you have flown it hehe.

PS, where are you from?

[thanhTran]

When I look at the multi stage gearing system, I thought it would be quiet, but I was wrong. Probably more gears cause more noise.

It looks like the designer designs the heli but forgets the place to hold battery :eek: :) I crash often and I don't like putting electronics & battery at risk. Maybe I'm just too paranoid.

Gaui also makes the minizoom, and its plastic parts look really nice & precise. Maybe it's also the case here?

Dont' see any indication says this heli is cheap (inexpensive?)

[eMeNeX]

The pricing isn't too bad for it. Heli, 2 Lipos, ESC, motor, BEC for around 650

[Tim Tompkins]

Where do you find pricing? TimT

[Tom Viper]

http://www.ezfly.se/hurricane_tlanda.jpg

I flew mine today and tried a friends 5S1P 4400mA pack, it was a one year old pack that he used in a plane. After 22 minutes it was to cold to continue, I couln't feel the sticks anymore.. But, there was plenty of power still in it. I was flying it on my 6S setup, 15T pinion, and the HS was about 1750. Didn't do any 3D, just cruising around and doing some rolls. Ok, some inverted as well, but my friend (the lipo pack owner) didn't like that much. continous saying...hey, stop that, fly easy/safe :D

But, for a someone who just wants a long flight time, the 5S4400 is the key!
I like the 6S better for 3D, so light and fast, flighttimes are around 7 minutes on a 2250mA pack, little longer on the 2500mA packs.

Max power 700W, current hovering 15A, 3D 30A
There is a reading up to 38A. I suggest to turn off the governor mode next time.

[Tom Viper]

That confirms the 15A hover, which is nice for large heli like this.
I must put on my eagle tree as well, and measure it with the 15T pinion, I should be below that. I am also using the 500mm blades.

[eMeNeX]

Hey Tom, what size is the bolt for the main blades. I'm guessing that Swift 520 woodies would fit fine if it's 4mm

[Tom Viper]

They fit fine! The bolts are 3mm, but spacers are included.

[tungym]

Well, some flier in Hong Kong just modified it with the heart of Trex 600- using Align Trex600 ESC and 1600kv BVL, changing the 1st plastic (small)gear to that of the 2nd plastic gear size. (I forgot the teeth no.) using 14T pinion and 550mm carbon+ 6s2p--->Woo!!! THe power to weight ratio(2.4kg with >1600W) is horrible and they are flying like magic!

I like the testing report! :) You can find the Eagle Tree recorder data with video. and more video.
The heli has released in Taiwan local. I just got one forme the dealer and start to build it.
"VERY EASY TO BUILD IT" Almost 80% ready, the weight of it is very light, only about 1.9kg with battery pack. I see the spec of Raptor E550 is 3.3kg.
I guess that's why Hurricane (ZOOM) 550ep can fit with T-REX battery pack and still has good 3D performance.

Whan I build it, I finded some small defects, Wanh I down everything, I will post here.

Does the kit come with motor and esc?

like this heli , but most importantly it all comes down to one thing . where can the US market get part support?

thats the thing we would like to know. im looking to get a trex600 over this cause there are parts everywhere in USA for it.

any idea? if not this would be a winner

[borneobear]

This is too good to be true. Is the price under $300

Not true. Turns out its selling for US$350 :

Anyone try this Hurrican EP550, and what's the performance with the stock motor and ESC + 6S1P as recommanded. thanks.

I got the combo set form Infinity Hobby.
Included 850Kv motor, 50A ESC and 20C 2250mAh.
Compair the heli with T-rex 450. (Sorry, I don have large size heli) I feel the power performance batter then the original T-REX 450SE combo, but same with my T-Rex 450. I used MEGA 16202 with Phoenix 45A and Aligh 16C battery pack in my T-REX 450SE.
I tried to use other carbon fiber 550 blade, but not wall as original 500 woods that included in box, and the motor was getting vary hot.
I never flown large size heli before, but compare with T-REX 450SE. It's much stable. When I do 3D fly, I fell like “slow motion”. I got more time to think how to fix my mistake. It’s not cause the heli slow-moving. Its cause the heli fly stable, I don't need to move my finger too much. GOOD! Highly recommand!

I used the orininal ESC on 550, but I have kick it out now. :p The ESC is ok, but I don't trust the ESC too much, because someone tell me the ESC is come frome the same manufacturer with Aligh ESC. and it's 50A ESC, but I got the max current over 50A almost 60A in my Eagle Tree data.
I say I used Phoneix 45A im my "T-Rex 450 SE" not 550 ^^.
Right now, I used Phoenix 60 in my 550. I fell good. Next few days, I will try Align BL600XL Motor.

[Tom Viper]

Bluepower, I have had about 29 flights on my Hurricane now, no problem with the ESC.
Did you acctually have a problem, or was it that it came from the same source as Align that made you afraid? The funny thing is that you can get very long flight times on this baby if you use 5S4200mA packs. Ok, not hard 3D performance,but normal sportsflying with some tic-tocs, piroflips thrown in (using the supplied 16T pinion). I am going to try the new Z-power 20 in it, to see what happends with the current.

mm....no any problem happened before I take it out. The reason just because I have really bad experience with Align ESC. I don't want to take any risk especially fly large size heli like it.
Thanks for your experience shareing, but I like "hard 3D" :) The original set is good enough but I want more :D :D more power, more fly time.
I think I will try bigger motor and bigger battery pack.

...so I had to try! I quickly made up a 6S pack of emoli´s to try, even if they are alot heavier, they worked well on the hurricane. Nice flighttime about 8-9 minutes of cruising (they weren't fully charged). I am going to try a 5S pack tomorrow, and see what happends.

Hello, Yes, I used the original BEC with 550mAh 7.4v Li-Po pack, but only enough for 2~3 fly times.. I haven't tried Align motor, If I do, it need the 61T main gear to exchange 42T main gear and use 15 or 16T pinion gear. I think BL600XL is ok for the motor mount.
There are some install tips, I think your should know.
1.check the tail pulley, it a little bit touch the tail gear box.

Tom, a ARF version, 90% assembled one. I did not take photos on the relevant position, but attached photo is the one I am building now. Day

[muda]

Are ball link or ballbearing movement not smooth?

[Tom Viper]

If the ball links are tight, use a sizer-tool to get them smooth. This is common on all new helicopters, and that tool is a very handy one to have.
Put on one link on the sizer-tool, rotate, and that link is then smooth as silk on the ball. I do this on all my heli´s, as they fly much better and precise afterwards.

If it´s something else, rebuild that part yourself. As I said, I have not had this problem, so I don´t know what it can be. I hope you solve it though.

[bluepower]

Bluepower,

What kind of flying one can expect with 6s1p 2200 20C on your setup ?

GOOD, I tried 2200 20C/ TP 2100 16C/ Energy Power 1850 16C. All ok for 3D fly. The power performance 2200 20C = TP 2100 16C > Energy Power 1850 16C.
But The weigh of TP and Energy Power are too light.
Price TP 2100 16C > 2200 20C > Energy Power 1850 16C
I am looking for 2500mAh 16C but low price pack. :)

Thanks for impresions. Can you compare this heli to Swift16 ? There I have big doubts about swift 3D'ing on these batteries.

I have both, and you are so right, you cannot compare them!
My Hurricane weight 1.9 KG AUW (inc LiPo), thats less then the Swift without LiPo´s! The Swift is much heavier, and you cannot get +/- 14 degree pitch on it. Not that you may need it, but for a short "burst" its quite impressive!

You will not have the flimsy ugly stuts to worry about nore spool down issues. And you have a driven tail for auto´s! Hate doing them without, and just have the Swift swing at me when ever it feels like...

[misskimo]

hey , well where you get parts from in the USA , any distrib here yet? like to get one for a thrasher 3D machine ,

[muda]

I think I'll be geting one as well.

[bluepower]

Ha...I think users in Taiwan are so lucky. I know some people try to cut the tail shorter and try 475 main blade, or more powerfur motor and batteries such like A123. others try to use stell gear to replace copper gear. let it can hanlde more power.
So...I guess the solution of how to get more power will be go larger or smaller.
Larger battery/ motor or shorter tail and main blade.

[muda]

There I am confused.
What I have seen on the video seemed to be a lots of power. Nice 3D.
Why somebody should want to cut boom or replace motor? So you wouldn't rate stock heli +motor+2 trex packs as 3D setup?

[Tom Viper]

I guess you will soon see someone with a 8S setup, 600mm blades and longer boom as well. If you haven´t allready? I know some people that flies it this way. Then there will always be someone with a 10-12S setup as well, with super power performance.

Me? I´m happy with the 6S setup. Cheap, fun and it will not break the bank when the ground starts to rush up against my Hurricane :D

I have now tried this diffrent combos:

Stock heli with 2 x 3S1P packs, good for 3D
Stock heli with 1 x 5S1P 4000mA pack, good for sportsflying and F3C style flights. Long flighttime!

Stock heli with 1 x 6S1P emoli pack, good for soft 3D, sportsflying and F3C style flights.

With Z20 motor and 530 carbonblades:
Z20 heli with 2 x 3S1P packs, very good for 3D!
Z20 heli with 1 x 5S1P 4000mA pack, good for 3D and long flighttime!
Z20 heli with 1 x 6S1P emoli pack, very good for soft 3D, sportsflying and F3C style flights.

The extra weight on the heli using emoli cells are acctually improving the stability for F3C flights and more relaxed sportsflying, rolls are more straight and loops can be made larger. Its like an arrow!

One need to take great care when installing the motor though, you need to use a bit of papper between the pinion and first maingear, I was not as carefull with this :( and after 43 flights, you could notice some wear on the first gear maingear. Nothing bad, but still unnessesary...

[muda]

What flight time on first setup when 3d?

Can you tell more about stock esc ?

[ddmt]

Tom, have you try the A123 cells?

[day]

Eventually I'm back after the blackout of internet caused by the Southern Taiwan earthquake last week. My EP550 already flown in the sky and was quite happy with the performance, but regret with a short fllight time of 4 mins. normal flying. I am not a 3D flyer and am looking for a longer flight time. Tom, I read from upstair you're talking about 5S1P 4400 mAH can fly for more than 10 mins. Please advise what Lipo you are using... thanks

I am buying a Hurricane/EP Hurricane 550 30Size EP RC Helicopter for "Sunday" heli flying at my nearby park and preparing to get heli certified by my AMA club. Several questions:
1. Has anyone flown it with this combo package below?
2. If yes, what is the length of time expected it; also for 11.1V 3S2P 3500 mAH?
3. Should I replace the Xtreme Power MG621 with the DS821 digital servos with my DX7?
4. How does it compare to the Century Swift, recognizing that it should be substancially lighter?

980 kv motor
Xtreme Power 14.8V 2200mAh 18C battery
RC-EXPERT 50A Brushless motor ESC
Xtreme Power MG621 Servo
Futaba S9254 Servo
Futaba GY401 Gyro

[Tom Viper]

Hi, it will not work with the 14,8V battery! You need a minimum of 5S, and go for 4000mA then.
Don´t know anything about that motor/esc, so I cant comment.

Day, I have tried the hyperion 5S 20C packs, they fit and work well.
The flight time will go up as soon as the packs (Gaui?) have been flown a couple of times, take it easy with them the first 5 charges, and use a balancer when charging.

[bryadelm]

I will check on replacing with lower 11.1V batteries for the Xtreme Power 14.8V 2200mAh 18C battery, which is x2 for 3S2P.

I also have 11.1V 3500mAh x2 for 3S2P that I plan on using.

[ozace]

Has anyone dealt with Infinity hobby ? i sent an email a few days back and no reply.
It said on the site the heli was going to be in stock on the 31st, still no show.

Is it a real store or some kind of ruse? I recently had an unpleasant experience with TT4U and dont really want another one here.

[chancechen]

Tom, have you try the A123 cells?

I'm flying EP550 with 7s A123. It's fine for 3D.
Original motor with 16t , Normal/Idle head speed is 1850/1950rpm
Peak current is 42Amp.

7s A123 is putting upon the battery frame (upper side)

[Tom Viper]

Ok, great news! Now I only need to order some A123 cells ;-)
Anyone have a good site or place for shopping these?

And, whats the deal with them? Do you charge 7 cells as 6?
Ozace, you use the 902 charger right, same as me, any problems with the A123 cells?

Tom, thank you for your response, I found one 5S1P 18.5V 2200mAH 12C here in Hong Kong, do you think this will fit, or I have to parallel link 2 pack in order to obtain 4400mAH.
