A friend of mine is building his first non-electric heli. He purchased a Radikal G20 with "Upgraded Aluminum Head Parts". He is having trouble getting the head together and has ask for my help.

He will be bringing it over this weekend. He says that the parts came without instructions and that he can't locate any online.

If anyone can point me towards instructions, this would be helpful.

If no instructions are out there, then can you guys post up a bunch of detailed close up pictures of the Aluminum Head. I know the flybar assembly is what is tripping him up the most.

THANKS in advance for any help or pictures you can offer up.

I don't suppose you happen to know WHICH aluminum head it is? afaik there isn't one designed specifically for the Radikal 50. Though there is a Century 50 upgrade alum head, and one for the Predator as well. There's also an alum head for the swift 620 I think.

If it's the century 50 aluminum head with the 6mm feathering spindle, then I don't think there ARE instructions for building it on the net anywhere. It doesn't come with instructions new either, but it is similar to the plastic head. The big difference is it's a little more adjustable for flybar ratios and whatnot.

If it is that head I'll try to get some pics of one with the flybar up when I get home tonight if you like.

If it can't hover, it ain't worth flying.

After speaking with him, I think it's the Century 50 aluminum head.

I'm sorry that I can't be more specific. This will be my first round with a century product.

The more pictures the better. THANKS

Yep, that's the one I've got. I've built 4 of these heads now, so if you need a hand when your buddy comes over, feel free to even give me a call if you get stuck. I'll get some pictures up of mine when I'm home.

The only thing I found was a bit of a pain was the spacers in the flybar cage. Real fiddly to get them in since there isn't much space to hold the spacer. Make sure you have something to catch it because you'll likely drop it a few times before you get it in.

Other than that the build should be pretty intuitive. For a little help have a look at http://www.centuryheli.com/support/...lBkltEdtn3.pdf. Though not exactly the same the design is pretty similar, so starting around page 5 of that manual should give you some idea of how things go together.

Like I said, drop me a PM if you need a hand. I'll even give you my phone number for if you get stuck if you want.

If it can't hover, it ain't worth flying.

Thanks for your great offer to help. I'll be keeping you in mind if we run into troubles.

I have been all over the century site and printed off several pages that will be of help.

Thanks for the heads up on the spacers.

Any pics that you all can post would be helpful too.

Here's a pic of that head on a Radikal (mine). Main thing to be aware of is the alloy head block is a bit longer than the plastic assembly from through bolt to the bottom and you will need to do some readjusting to get full +/- pitch without the washout hitting the bottom of the head block on full positive pitch. It helps tremendously to also use the alloy washout assembly as the alloy slider block is a tiny bit shorter than the plastic one and it makes getting the setup right a lot easier.

I'd get some better pics, but the heli is at home in Boston and I'm in Vegas at the moment, won't be back until late Saturday...
