Help!
HK 450 or HK 600

Ok, I have my HK 450 and I really like the way she flies. Now I see that Hobby King has an HK 600. http://www.hobbycity.com/hobbycity/s...t__w/o_blades_

almost 4 feet long. Is is safe to assume that she would be as stable if not more stable in flight than the HK 450? Can I use my Gyro for my 450 on this bird?

Sincerely,
Karl in Colorado

A 600 is more stable than a 450, miles better... but I would want to wait on this one... the HK-500 didn't get good reviews - lots of problems with that one. Some gyros will work on many different helis, but some won't... either way, you're not going to want to tear down a 450 if you like it. I have a 250, 450 and 500, and I like flying all of them, and it's good for building your skills.

I agree with jasmine, I have a 600 comming, but I also am not a beginer, and have enough expierience to find potential problems before a flight. A heli this big is also much more money to have hangin in the air, and might not be a good beginer heli, I learned on a twitchy blade CP, and I am a better pilot because of it, if you can learn to fly the smaller less stable helis, than when you step up to a bigger one you will be that much farther ahead!

Well I was thinking more along the lines of a poor quality 600 is more of a safety hazard. The forces involved in a 600 size are not to be messed with.

I picked up a 500 heli and you will be amazed at how big it looks next to the 450. I think the 500 might be a nice upgrade for ya as the parts will be cheaper than the 600. I'm putting together a 500gt and it looks like it a pretty nice copter and for the $$$$ its hard to beat. The size and weight of the 500 bothers me a bit though. It could do some serious damage if you are not careful. I would recommend a good radio and to only fly it at a sanctioned field. The 600 must be a monster.

Even to assemble a HK600 will cost some jack, at least $700-$800 for a cheap build which I would not recommend. Go for a TREX500 ESP, I found a bargin at helipross.com (not heliproz, a US distrobutor) for ~$440 + $30 EMS. The kit is complete, just add a gyro and tail servo.

Good luck and happy shopping, I am assembling my TREX500 (not the ESP ) but it still looks HOT!

700-800? where did you get that? aside from the gyro and tail servo I am gonna have less that 400 bucks into it including 2 batterys... and that is with an align motor and scannerRC servos.

well as far as "poor" quality is concerned, I have seen HK aluminum, and it is as nice as align stuff, I have a 450 tail hub and grips from HK and from align, and I think the finish is nicer on the HK, I have also seen my align metal parts fail on me, while a guy I fly with has a HK metal head and tail and he has tons of flights over 3k headspeed, and no issues,

I agree that the HK plastic leaves somthing to be desired, but the metal parts from skya that HK sells are the same as EXI if I remember right, and is nice stuff. That said, I will probably swap in an align feathering shaft and feathering shaft screws.

I've done some research in the last month or so, I have 2 500s in the works and was hoping for a low cost 600. After looking into it I decided to stick with the 500s, I just can't afford it.

Do you have a list of components?

My low cost EXI500 plastic edition is:
EXI500 $77
RCtimer 80a ESC (this is a cheap experiment, will likely upgrade to a Plush 80a) $25
3xTurnigy MG930 $50 w/shipping from HC
Hk500 motor $25 w/shipping from HC
GWSpark t-servo $16 w/shipping from HC
HK401 $16 w/shipping from HC
Exceed uBEC $20 w/shipping from Hobbypartz
AR6200 $70 w/shipping from bigskyhobby.com
CF Blades $20 w/shipping from Hobbypartz
Align tail grip assemble $15 w/shipping


Total $319

2 3s 2650 mAh 20C paks $40 w/shipping from HC
(that's 1 6s pak)

TOTAL for my low cost 500 is $359

I believe the above is a quality build no matter what the clone haters think, subtrace $36 for the gyro and servo and the total is $323. Only $80 for a 600 size, I am doubious

You build that, and a genuine 500 with decent electronics and a better battery, then you fly them both and compare. Until you do that, you won't know what I'm saying. It's not an issue of clone hating... if you put that electronics package on a Trex, it would fly like crap too.

in the works, I have a TREX500, align motor, align ESC, GY401 with hyperion digital tail servo. It should be complete by this weekend. What an impressive machine, my EXI plastic has shipped, it is anywhere near the quality of the EXI450SE I will be completely impressed.

These low cost clones are not bad, will it last 1000 flights...only time will tell. I'm still learning so I am willing to experiment.

That low cost ESC is my only real concern on my cheap 500 build, but my typical flight trials will likely sort out if this is a hazard or a bargain.

Let you know how it works.

I guess your saying if the servo does not say futaba or hitec it will be crap and if the gyro is not SMM it is not worthy? I disagree...but honestly, I have no real basis for that opinion at this point as I have been at the lower end of the hobby since I have been in it

I've had bad centering servos, it really sucks eggs, but now I test all my servos before installing them, never had one fail in flight, but the plastic ones strip in a crash. I've had good luck with the servos I use and keep in my parts bin.

The piezo gyros seem adequate for my current skill, and lots of RC heli pilots do impressive stuff using some of these low cost gyros.

I don't really know what you are speaking of, I typically don't purchase anything without a good user track record and I've had great luck. I haven't had any problems. I'm not sparing anything for my Align build, it really will be interesting to see how big jack stacks up against prudently researched low cost electronics. I've had good luck with flightmax batteries...guess I'm the lucky one

I would not be willing to spend almost $400 to find out. I'm not an equipment tester with unlimited funds. I want it to work the first time, and if it doesn't, I want to deal with a company who will support it. I had a Hitec servo fail for no apparent reason - it was replaced with no questions asked.

Kyle Stacy and Alan Szabo and Tareq have the ability to deal with wonky heading control - their skills are so hot, they can fly a crappy setup and make it look good. Most beginners do not have that ability, which is why I recommend rock solid parts for beginners - they are already struggling to learn, and dealing with spontaneous bad behaviors in their aircraft is not something they have the skills to handle.

jasmine, with all do respect, there are things from hobby city that preform as well as name brand stuff. I get kinda ruffled when I hear people say you cant build things on the cheap that will fly nice, I will put my low cost protos against your rex500 anyday, and show you haw a real heli flies.

that said, here is my current cost and parts list for my 600 expieriment.

HK600 kit, $139.99
used 650L $50
turnigy 85-100a esc $45
3x scannerRC 9764MGs $60 shipped
3D Carbon blades $25
2 zippy 5000 6s1p 20c $98
Shipping from HK $46

Total is $464 so I was a bit off with the secound battery.

Go ahead and tell mr the 20 zippys wont last, thats what I heard abot the 3000 20c I bought for my protos, and it has more power than my 40c turnigy. The servos are a little slow, but have had good reviews from people with 600 birds, and they feel like quality servos when I pulled them out of the box. I have a 401/9254 for the tail.
