For information: I've tried to add to this kit Servos and find really strange thing. When i added recommended HXT900 1 or 2 or 3 pcs i still have got choice between two delivery options: chip and expensive. But if added HXT900 4 and more pcs - it was only expensive one. That was not connected with weight (less then 1 kg) So i had to choose Turnigy TG9e 9g and i ordered 7! and still got chip delivery.

Yes, HK messed up with it, they have strange rules and limitations for ordering. I for example could not order 8 HXT900 servos, not even via expansive shipment.

Main rotor blades are included?
 r_g_r 1320 points
Yes main rotor blades are included. Only cheap plastic ones. But they will doe the job for a beginner. If you are already a better flyer I would suggest to order some 325mm glass-fiber or carbon blades. Or you might directly go for the HK450GT kit if you want a more durable overall solution.

Can i use 3800KV motor(450) with 10 teeth pinion for this kit? What is depend of tooth number?
 r_g_r 1320 points
3800KV is bit much for the HK450. In general around 3500KV is a good fit for this heli. Using from 11T to 13T pinions (depending on how fast you want your head speed). You might get away with the 3800KV and the very small 10T pinion. But higher KV motors usually means that more amps run through them which will limit the flight time compared to a lower KV motor with a larger pinion.

BTW: If you are looking for parts you should google for "HK450 Configurator". This is a tool to help you find perfectly matching parts for this heli that are all available here at HobbyKing.

ok, maybe i was unlucky but the tail boom needed to be cut to fit the tail rotor housing (see forum topic 'belt too short??'), also the screws are way too soft, i rounded off two screws and i was CAREFUL. The main gear was very slightly bent so i've replaced this with a trex one (i might of gotten away with it but replaced just incase). That being said would i would buy another? MOST DEFINATLEY, considering the price and the fact most of the head is metal. The main shaft, head and swashplate assembly are very smooth and there's no problems with binding. The tail gear pulley is metal and again very smooth. For someone with a bit of experience this heli is a fantastic deal and i suppose for the newbie, prepare to have to 'tinker' with the kit to get it perfect all in all a good buy and sent to the U.K within three days!!, thanks HK

I´ve received it. Everything is precise and works smooth, combination of metal and plastics (plastic parts - probably composite plastic - looks worse than HK450 V1 I think). Included pair of full plastic 325mm blades, looks exactly as Align basic blades. Main frame is the same as V1, but included metal tail shaft gear. Canopy holders are metalic. All parts are tuned to black/grey colors. Good work HobbyKing, this heli is winner for its ratio between price/quality!

Pretty nice machine.Build went well except for some slightly misaligned holes in the bottom base plate,being plastic this wasn't really a problem i managed to get the screws in.I also did notice that the metal gear pulley/shaft that drives the belt for the tail rotor is bent a noticeable bit.The head is all metal except for the blade grips themselves,for the price this is definitely worth it i cannot comment on flight performance a sit is not ready.

This kit came in a much smaller box than I 'm used to with other helicopters, but it was packaged really nicely and all was complete. I purchased all the alu parts available with it, which makes it a really nice heli!!
