Finally, a 550 class helicopter kit that won't break the bank! Modeled on the famous and proven T-Rex 550, the HK550GT will push your 3D skills to their limits.
This 550 size helicopter offers an excellent power-to-weight ratio that makes for stellar 3D performance. It utilizes the same power system as a 600/.50 size electric heli, but is lighter and spinning smaller blades, thus offering much higher performance and efficiency.
With its black anodized CNC alloy head & tail unit and beautifully finished carbon fiber frame, the HK550GT is as nice to look at as it is to fly. This kit has just about all the alloy upgrade parts you could want already installed such as battery mount plate, tail servo mount, tail pushrod guides, anti-rotation bracket base and main bearing blocks. There are very few plastic parts anywhere on this heli!
The HK550GT uses high quality tail bearings and tight tolerances to ensure no slop in the tail assembly and locked-in tail performance for the most extreme of 3D flying.
This heli comes 90% pre-assembled so you can be in the air in no time. Just complete the final assembly, add your favorite main blades, install your own electronics and your ready to fly!
Features: • Black anodized CNC alloy head & tail unit. • High-strength alloy main bearing blocks. • Alloy battery mounting plate. • Alloy tail servo mount. • Beautifully finished carbon fiber main frames. • High quality tail bearings and tight tolerances to ensure no slop in the tail assembly. • Excellent power-to-weight ratio. • Compatible with T-Rex 550 helicopter. • 90% pre-assembled.
Bonjour à* tous, j'ai une paire de pales de 550 mm. Puis-je les utiliser sur mon HK 550? elles me semblent un peu proches du rotor d'anti-couple. Quelqu'un utilise ce type de pales? Merci!
I'd like to use the Turnigy T600 (1100KV) my HK-550GT. I've read that in 600 frame you have to modify it a bit, but, in 550 frame? Are the 550 and 600 frames identical in size? HK support people recommended me that motor, but didn't say anything about modifying the frame, what do you think? I appreciate your answer! Thank you.
The HK-550GT and the HK-600GT do not share the same frames.They are totally different.In order to use the T600 motor,you will have to modify the frame slightly to accommodate the side clearances required for this motor.You can find the necessary information through a Google search which will show you which areas need to be cut out.It is easier to do than it sounds.
LuckAR,I posted some pictures for you to look at in the files section.I hope you find the pics useful and pretty self explanatory.Happy New Year everyone!
Cheers
Turbo
Turbo, you rock! Thanks for your answer.
If you don't mind, two more questions:
1) Do you recommend this motor for this kit (instead of any other turnigy motor that HK sells)?
2) In the files you posted you use the 880 Kv version. Do you recommend 880 KV? I've ordered 550mm main blades.
Thanks in advance!
LuckAr,I answered your last post but someone at HK seen fit to delete my post responding to your questions.Not the first time this has happened either.Sorry about that dude.I tried to help you out but the HK posting police are at their finest again...and people wonder why they can't get answers to their questions.Excuse me HK for trying to help out a fellow modeler.Sue me.
Are there still serious issues with regards to bearing quality and tolerances with the current HK-550 line of helicopters.After doing a ton of research on these heli's I've decided to hold off ordering one as there are just too many warning flags going off here with regards to quality control issues and un-useable poor quality fit and finish parts.There are just way too many people commenting on exactly the same issues and concerns to convince me that this is a well thought out purchase.Quite a few kits got sold over the "Black Friday' and "Cyber Week" sales so we'll just have to wait and see what issues they have with their current kits.Please keep us posted guy's.
I'm not a 3D expert, but just a very cool flyer and my 550 will receive the Turnigy Typhoon 500H Heli Motor 1800kv with 4S on 5000 or 5800 mAh. Just need to change motor pinion for a 15-16 tooth to have a 1800-2000 rpm rotor. This motor has a lot of power for low A, I've tested it on my 500GT (15 min of flight on 4S 5000mAh)
T.T is much more efficient. Smoother. easier on batteries. Has a much more locked in feel. 90% of pros that fly compition fly t.t with reasons mentioned. however Belt is more forgiving in a crash. If your a noob And want to give t.t a try, Use an xtra large vertical fin to avoid tail blade ground strikes on tail in landings.
1 on all of the above! For HK, it would surely make sense to have an FBL version, since they will then have the chance to sell more FBL controllers and more higher quality servos. Glad they finally came out with the 550, but I'll wait for the right version before shelling out for one.
HK Please when you do put the TT version into production make sure the umbrella gears are made of good materials and will stand up to the stress of 3D flying! The gears on the 450 Pro TT are absolutely worthless! I stripped 4 sets before I installed a set from Align and the Align gears have been flying for 4 months. Hope this will not be the case with the 550TT.
With everyone wanting TT in the kit, but saying they have to change the soft umbrella why not buy the belt then get the Align TT. At least you will have a better TT drive train with Align and you can get the kit now.
It mentions that many parts are made of an alloy material. Could you tell me what metals are included in the alloy?
Thanks http://www.hobbyking.com/hobbyking/store/images/em_s mile.gif
Generally, Aluminum alloy 7075 is used for R/C heli parts, especially head, and tail parts. Other aluminum alloys may be used for non-stressed parts like battery trays etc. Landing skid tubes are usually a 2000 series aluminum alloy, usually 2024.
7075 is ~3x more expensive compared to 6000 series so I doubt they are using better alloys...
EN AW 7075 -T6 and 2024 are both very good aluminum alloys.
I really dont understand that thinking as the FBL version has less parts, and less material costs, less machine time etc. The FBL version should be cheaper!!
When will this kit be available in the German warehouse, for European customers ?
I do want to aquire it, but rather not pay shipping costs taxes extra import costs.
This heli looks promising! If the initial reviews are good (no major parts failure/crashes from inferior parts) and the price stays low...I'll pick one of these up. I have the HK450 and it is still holding strong after 300 flights! Bearings didn't seem to last as long as Align bearings, but they are a wear item anyhow.
I know. Its $143 for me. This could possibly be because this is a high performance machine compared to the HK 600 GT. Still, with the recent release of the HK 450 FBL, you would think that this machine would be both torque tube and flybarless at this price. Maybe it will go down in a few days.
if you feel like waiting for the flybarless and torgue tube save your money....or you can get this now and buy the tt and flybarless when you crash with the Align parts........myself I'm going with the AR7200BX with the 550 DFC head
HK should bring 100 of this Item to euro warehouse, I think they will be sold out in less then a week, if price difference is not to much, what it unfortunately mostly is. As of now it already is 1,5 times the price of a gaui 425 in germany, which you can upgrade to a 550 with a 20 Dollar upgrade. so it will be a hard fight against gaui. We´*ll see. I´*m very interested on first reviews.
3 things are homework for HK.
1. Flybarless Version
2. Scale fuselages such as Bell 206 or Airwolf
though any fuse that does not need an extra angeled gear to higher the tail-rotor, or offer that kind of gear.
3. All that in Euro warehouse
my wish is , a komplete setup for any Heli in the german Warehouse / Servos, Battery Gyro BEC,, etc.
so and i thanks GOD and Hobby King, the new 550 Heli is a Belt-Drive ,, great
I bought a 550 and am amazed at the good value for money. This heli flys as well as helis worth 5 times as much. Very well engineered aqnd a very good heli, i t is every bit as good as its competititors.

I have just received my HK550GT today 5-25-12
It seems to be very high quality and Very nice kit for the money.
Sorry if I won't be able to give you a "builder's review" or "flying test" at this time. But i will be checking every screw and reloctiting and checking the thrust bearings to see if they have been greased I've yet to see thrust bearings come greased in any of these kits. Like always no manual but a Trex 550 manual can be downloaded

After owning all versions of HK's helis I jumped on this one. I really wanted the TT version but I couldnt wait (figured I'd get the conversion when it came out). I was very please with the quality of the 550 when I took the parts out of the box. It seems they've geared up thier engineering. Don't have any flight reviews just yet but the build was going great until I realized I had two tail rotor push rods and no flybar. Also, the stock canopy was strached pretty bad when I pulled it out of the box - didn't really care about that because I always replace the stock plastic canopy with one of higher quality.
For those wanting this kit - I suggest waiting until HK has flybars included in the boxes that are sitting on the self.

j'ai osé essayer cet hélico "low cost", évidement il y a mieux mais pour le prix c'est parfait, le débutant aura un équivalent shuttle (tout métal avec flancs carbone quand même) , pour s'entrainer ,même au 3D c'est moins stressant car le risque financier est moindre. la taille permet de transporter facilement. simplement génial , je vais en recommander un deuxième comme mulet et je ne prendrai plus de risque avec mon hirobo eagle

I now have the 550 flying and am pleased with the way it performs.However there are a few issues that potential buyers should pay particular attention to.I always like to spin the heli without blades to check vibration,and after the second time my tailshaft bearings collapsed which is strange when hk state that they are high tolerance bearings.The tail boom support rods came out of there sleeves,a few of the main shaft screws were loose (no locktight) and quite a few holes had to be clearance drilled in the c/f frame. Finally I was supplied with two tail pushrods but no flybar. I will still be buying from hk as the value for money connot be bettered but as always will continue to check and double check all components prior to flying.
