HK600GT Build (Game ON)

[Donnie D]

One thing about it, the more you tear down and rebuild, the more you are gonna know about your heli and the more you will learn. There is something to be said for that.

I must have got lucky on the 3 HK 600GT's that I built, they all work great with a minimal amount of new parts and a CRAP load of tinkering, but they all fly great. One thing is they are not built to do 3d, if 3D is your goal its best to skip the HK 600GT all together but for basic flight, AP and scale then I think they work fine. But there are mixed results in the kits.

Now I will say this, both the HK 500GT's I bought were HORRIBLE, ended up getting rid of both they were soo bad and I would never buy another one again.

I've said time and time again the HK 600GT is a builders kit for people who like to tinker, you will have defective parts, some more then others but it is a clone

Marc, What was so bad about the HK 500GT's? I know my EXI 500 plastic kit was not very good, and I had to do a lot of work to get it flying properly! Just curious about the HK 500GT. I wonder if the HK 500CMT would be any better?

[Nuttcaze]

I put alot of time trying to get them flying smooth, never did get either to do so, they just needed more new parts then I was willing to replace. The HK 500GT is basically the same as the EXI 500 Plastic kit. 

[old_city_painter]

Yeah, I know all about the EXI plastic kit! Do you think yhe HK CMT would be any better, or the EXI all metal kit?

[Nuttcaze]

I'm thinking the EXI Carbon Edition would be the best of the bunch, the HK 500 CMT is nice but after the other 2 500's I don't think I wanna try another HK 500 of any kind for quite a while

You guys have me flip flopping back and forth on this. I changed my mind and I am going to get the align replacements. But I am going to make this a budget build and save money for a genuine align machine in the future. I'll post my build information as I get the parts. This heli won't be seeing and hard pitch pumps or inverted flight, so I'll be making my electronics purchases based on that.

If ya'll are interested in an Align 500 kit BP Hobbies has a closeout sale going on. http://www.bphobbies.com/view.asp?id=D1006220&pid=D1017109 This kit for the price is great. Comes with the Align motor, Align ESC, I'm not sure whether it has main blades or not. The frame is Glass Fiber which will work well. I have a GF frame on my Align 600 and it works fine. Once these are gone, there will be no more available. Just thought I would give you a heads up! Seeing as how you have had so much trouble with the clones!

okay after reading the last 5 or 6 post, i feel i made a bad choice. I just got the EXi plastic kit. Is it really as bad as you both say it is !?!?!?!

[old_city_painter]

Megashane13, No, not a bad choice, or an especially bad kit! It will just take some parts replacements like any other clone kit to bring it up to speed! I am using the EXI plastic kit in a scale fuselage and it flies very well! Attention to detail will get the machine to where it needs to be. These are the parts I replaced on my kit with Align parts unless otherwise noted:

1) main shaft

2) feathering shaft and thrust bearings

3) main gear set (upper and lower) I used the EXI center hub with the one-way bearing. I've had no issues.

4) tail drive gear with bearings ( gear which drives the belt off of the lower main gear)

5) CNC washout arms( EXI parts from Xheli)

6) CNC mixing arms ( EXI parts from Xheli)

7) Complete linkage rod and ball link set ( This is important, the stock EXI links are very poor fitting. However the Align ball links are larger in diameter where the linkage rods screw in so you have to buy both linkage rods and ball links from Align.)

8) tail rotor shaft ( mine was slightly bent)

That's it! Sounds like a lot, but these parts are not very expensive, and they make a world of difference as far as everything working smoothly. Make sure you check absolutely EVERYTHING on your kit, all screws, fits between parts, especially in the rotor head assembly. A complete teardown is recommended, and don't forget the thread lock!

Align DS610 Tail servo

Looks real good! I might suggest the Align 620 or 650 servo for the tail. The 620 is a tad faster than the 610, and the 650 is real quick! The Turnigy gyro will do, but you might want to upgrade sometime down the road. As Marc and I have both mentioned, replace the main gears and tail drive gear for sure with the Align parts. And do check everything as you build up the kit!

[srk.heli]

Sorry, I actually wanted to write Align DS620 in that post. I'll go fix it.

I made an align parts order from grandrc yesterday. It consisted of:

1    H60004 Metal Main Rotor Housing
   T-REX-60004    23.99    $ 23.99
1    H60159 Main Shaft
   T-REX-60159    12.99    $ 12.99
1    H60007 SF Mixing Arm
   T-REX-60007    10.99    $ 10.99
1    HN6001 Metal Flybar Control Arm
   HN6001    14.99    $ 14.99
1    H60034 Tail Drive Gear Assembly
   T-REX-60034    9.99    $ 9.99
1    H60161 Main Blade Linkage Rod
   T-REX-60161    3.99    $ 3.99

I'm going to try the new gray main gears and see what happens. If they are crap, I'll go to the LHS and get the align set.

I would go with a 30C battery at least..
