HK-550GT 3D Belt-Drive Electric Helicopter Kit

HK-550GT 3D Belt-Drive Electric Helicopter Kit
HK-550GT 3D Belt-Drive Electric Helicopter Kit

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!

Most of the screw heads are using 2.5mm size hex wrench. Better use heavy-duty tool type, otherwise the hex hole become loosen and damaged.. might bring you more harder job to finish your heli buildup.

Hk servo BL89601 is a bit longer when fitted to aileron and pit slots. Need to add spacer such as washers or something similar. target=_blank>hkservoBL89601

To assemble the tail, I have to unscrew the plastic tail boom holder. By doing so, enable me to hook the belt onto the gear. This make make me more fingers out!

Mine arrived home yesterday 14Feb15. Found only 1 item broken i.e canopy. It was not wrapped with plastic bubbles. Hope HK will improve packing method. Anyway I thank too to all HK staff becase the parcel already safe on my hand for only a week delivery. :)

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.

А в чём прикол? Брал такой же, но Всё косое и кривое. Из угля только Ещё и с движком Skorpion за заказ приняли, а потом вежливо что мол по такой цене уже нет, хотя на момен заказа всё OK! Пришло

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.
