You can take a look at the unboxing video that I created. You'll find it in the "VIDEOS" tab above or on youtube (Unboxing the HobbyKing HK450 v2 helicopter kit)

r_g_r! You are absolutely right. Today I've hovered well) But I think this kit very heavy in comparing with my crashed carbon Belt edition and lifting force of kit blades less then regular. So I turned up collective pitch by control thing RC side and magic was there. And I am still shocked of kit quality: tail blades had very different pitch and i fix it by BENDING!! aluminium arms... Is that I was so 'happy'? But more hobby time)!

I've tried to hover with black fake blades - it is impossible)) Only funny jumping on full throttle - very 'useful' item for 'test' purpose)

The plastic blades that came with my HK450 were OK for hovering and for simply flying around. Then I would guess you did your CCPM setup wrong. You should never need full throttle to hover. I hover my HK450 at about 55% - 60% throttle. Double-Check your complete CCPM setup, especially the swash setup and the pitch setup. I don't know how exactly you did your CCPM setup, but just in case you are a beginner I recommend to watch several different videos to get a better understanding. Search on youtube for "Trex 450 ccpm setup" there are tons of good videos out there.

How do I find out which parts are compatible with this kit? Like motors, ESC flybarless conversion things like that....
 r_g_r 1334 points
I recommend to search on google for "HK450 Configurator". There you find a tool that helps to find the best matching components to setup an HK450. All the components that this tool suggests are available here at HobbyKing, so no need to order from different suppliers.

Gerry01! Could you suggest what should i do with notreal_blades. Does it make sense balance, install, fix 'butterfly' and hover awhile.. If i can not fly with it - what's a propose of this item so i need to repeat all steps with real blades. Still can not accept that i missed last days of flying weather... Is it possible to fly 'calm' - blades have strange profile and less width?

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!!
