Now I must say why the T7 screws? If like me you only have one and it breaks (a few times) and you have a few T6 drives. You can file down a T6 and it will become a T7 if filed enough!

Don,t buy this item the shipping costest twice as much as the heli
 jeff 2 points
I already did. $20 bucks shipping. Got it in 2 days. I got sold on a post somewhere to start out on this one bcuz it's cheap and more "c" friendly. I almost have it ready to fly. Forgot a pinion. No hurry. The weather has been freaking terrible. Still... For less than $50 sounded pretty fair. Thx
 NewToHobbyKing 15015 points
Jordan why did you not buy it from the Aus Warehouse. We had a sale on just week ago, and it would of been cheaper postage. That said I got mine from here and postage was only $16.50US and got the Kit for Twenty-five US on the sale week!

This will be my 1st 6ch and biggest heli yet. Can someone recommend what size battery I should start out with? I ordered aTyphoon 450H 2215H Heli Motor 3550kv and Hobbyking YEP 40A (2~6S) SBEC Brushless Speed Controller. I have a 2-3cell charger. I am thinking 2200mah in the 20-30c range. I just long easy flight without using the "C" word. Thanks.

You should use the 2200mah 3S batteries* discharge rate should be no less than 35C for good performance and longer flights.

Sounds good, but the ones I have are 20c. I guess they'll help get it off the ground so I can at least get comfortable hovering. I've only flown the v911 and am getting better with the 120sr between repairs :-). I've been researching what batteries to go with and am leaning towards 6s 1300mah with a 1700kv motor. Not sure about the pinion but should be shooting for a 2500-3500 rpm headspeed. What do you think? I'm in no hurry to spend the money. None waisted except for a 3550kv motor. Still need proper batteries and a new charger if I decide to go with HV. The. Jeff

This heli is not designed for 6S setup. The 6S setup is for the flybarless helis, use the 3S setup if you are just starting out. The cost is much less and the heli will have more than enough power for what you are doing. Spend your money on good servos, esc, gyro, blades and spare parts. Wha pinion are you using on the 3550 kva motor?? The 14T pinion should give you good head speed (3440) and at least a 6min flight.
 jeff 2 points
Hi. I am waiting on a 12t pinion just what the manual recommended. I'll look into getting a 14t. If my headspeed is to high can I just lower the throttle Max? B4 I buy some 35c lipos, what would the difference be with 6s? More power? Couldn't I just tone everything down with a the Tx and a governor? I found a good charger so any cell count is now an option.
 Snake92 59 points
If you use your throttle curve to lower your rpm the esc may get hot because the pulse rate is not at the optimum. The esc works best at over 85% throttle. The best way to limit head speed is by using a smaller pinion or lower kva motor. Don't fret the 12T should be just fine and you should be able to run the heli at 90 or even 100% throttle with no problem. Remember for electric helis there is no curve in the throttle curve like with Nitro helis, use 90, INH, 90, INH, 90 or 100, INH, 100, INH. 100 in the Idle up 1 or 2 curve so you end up with a horizontal line. The normal mode curve would be set so that at mid throttle the curve would be at the max for idle up 1 eg 0, INH 90, INH 90 or 0, INH, 100, INH, 100. With your throttle curve set like this you can start up at Normal mode and switch to Idle Up1 while still on the ground without the heli jerking. Hope this helps.

Thx. It helps a little. I'm not all there yet. Set the tx once when it was new for my blade 120sr. I understand aboט*t the esc needing to not be worked hard. I just am not understanding why a 6s lipo setup would change flight characteristics if headspeed is the same...?
 Snake92 59 points
The FBL system is much lighter and has less moving parts than the flybar system. The rotor efficiency will not be enhanced with a bigger battery ie the 6S. Also, the cost of the 6S battery is much much more than the 3S battery. In the end it is your choice which ever you use but as a new pilot you should focus on efficiency and cost effectiveness before taking the plunge into HV setups. Just my 2 cents worth.
 jeff 2 points
Alright. Thx. You think my 20c will be alright at first for hovering? If so then I'm just waiting for a pinion and final adjustment.
 jeff 2 points
Ouch! Are you sure. 3s 35c lipo. Easy to forget how much batteries cost.
 Snake92 59 points
If you think the 35C batteries are expensive with till you try getting a HV System with 6S batteries. The 20C is fine but if you want more power you will need the higher C rate batteries.

May I ask everybody how their HK450 came (ie: just a lot of bits or some assembled)? And is there a manual saying what to do with the parts, that came in the kit? (Hay I got all my parts but some are assembled).
 joseph 49 points
they all come semi assembled first thing you should do is set aside the larger bag of silver screws they are spares and will confuse you all the parts come packaged with the screws needed for that part
 NewToHobbyKing 15015 points
Joseph (I will award you) so the "semi assembled parts" can I assume that are RIGHT. Do they need loctite? Have they been? Does any of the screws need "Loctite"? Please.
 joseph 49 points
you dont ''need'' any and plastic cant contact lock tight some people redo all the metal to metal stuff but its already been done

Thanks, that is what I wanted to hear! Now is there a Manual showing how to put, the pre built modules together or do I just use the "kit manual" and jump the done stuff!

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!!
