Reply with quote

I have been thinking about taking the plunge on a 500 size heli. The kits on hobbyking king certainly look good value but are they any good. Has anybody on here got any experience with them. It would definately be a bad idea on a heli of this size if bits start coming off in flight. I do have the t-rex 450 pro which i built and that went together really well and fly's superbly so i am tempted to stick with Align for the quality. Opinions would be greatly appreciated.

Stuff is cheap for a reason, but then spares will be commensurate. And if you envisage a few dings, it may be the way to go. Then when you're happy, upgrade to something more expensive.

I settled on a Tarot 450 FBL ultimately because AFAIK, they're owned by Align, are much cheaper, have about the same quality (some say better), and extensive good reviews.

And I read too many reviews about HK stuff which put me right off...

I have a number of Hobby King Heli's, 450's, 500's and 600 and there have been very few issues with any. I do scale flying so there is less stress on the parts than the wild 3-D guys, but my investment per heli is much greater than the "average" 3-D machine so I am NOT inclined to use junk and risk a few thousand $$ to save a few hundred.
One of the main knocks I see on the HK helis is the screws. When I disassemble and re Loc-Tite my mechanics I replace ANY suspect retainers (screws) and I will say this...Even those have been few and far between. I have had a number of Walkera socket head cap screws twist off at the head or strip in the aluminum mating part, but as I said, very few HK's.
Soft aluminum is another issue, and I have had but one instance where I felt the grade of aluminum was an issue and that was on a boom block on a 450 about three years ago.

Bottom Line...I would (and do!) use the HK heli pod and boom mechanics with confidence they will not fail with reasonable care and inspection during the assembly.

Hi Chopper,

I have a HK250GT and have no issues with it other than cheap screws, if you order one buy a full set of replacement screw at the same time they cost about $4.00 and will give you plenty of spares. I looked at replacing them with RCscrewz but the set were twice the cost of the HK250 kit.

He friend has a HK450 and actually likes it better than his Align 450 says it is smoother to fly.

Thanks admiral. That confirms my decision.
I will get to work on the wife immediately. I might have to wait a while because i have only just got the Blade 130x and the dx8.

Chopper 54.....

It slipped my mind during the fist writing but there is one other area in the larger (500 and 600) size HK heli kit that probably will need attention.
The main and AR (auto rotation) gears will probably need to be replaced as they almost always come warped from the factory. I have replaced all my 500 and 600 size main and AR gears with genuine Align or TAROT gears. Both are superior to the HK gears.

I have own an HK500 for a year now. I think the quality is very good considering the price. The only problem I encountered was the "Inadequate tail gear mesh" and it took me less than hour to fix it.
This link will tell you all common problems of HK500. But don't be discouraged by it, for me I only had one problem of gear mesh to fix.

Hi Chopper,

Hobbyking UK are located some where in your county, you might be able to collect in person, and they probably have some helis on display even demo models, so you could get a close up look at them.
