muscat69: Metal Head.

I put one on yesterday just for fun. It is tighter and seemed a little bit smoother.
The metal head I put on was ordered from Hong Kong... and was fairly inexpensive.
BUT BE WARNED.... you have a bunch of tiny little screws with the ball links on every
link and the swash plate. Silly me I didn't think to tighten them all down and on first
spin up (luckily on the workbench) one of the screws on a ball link came undone.
I was lucky that I found both the ball link and the tiny little screw... but it would
have been very difficult to replace either part.
The blade holders are wider than the blades so the blades don't fit snuggly and I will have to add
a spacer so the blades sit properly.
It is a lot easier to replace a ball link
on a plastic part with a LOSBI 51 brass ball link at 50cents a pop. And they are strong.
My metal head also came with the holes in the fly bar head (the piece that the little pins in the t-block slide into) drilled off center and I had to re drill them for proper fit.
If you do get a metal head, I would strongly suggest you remove ever little screw in the complete unit and super glue them back in or at least use Lock Tite.
I have four metal head assemblies... one I just put in as mentioned (and took out).
Two have the ball links with tiny screws (two pieces, screw and ball), the other two have ball links with that are one piece and screwed in with allen heads... these two look to be made better.

I flew it a couple of times yesterday.... and put the plastic head assembly back in and I'm just happy with the plastic.

Empty Wallet:
Haven't heard from you in awhile... those mailboxes still holding up ?
Flying in dead air makes all the difference in the world. Sometimes there can be layers of cold and warm air close to the ground that will make you think what in the world is going on.

Have you tried desensitizing the servos... the arms that come out of the servos have three hole positions... moving the connecting link in will desensitize the movements making it easier to fly.
You will still have plenty of control. The trick to putting those tiny little brass pins back in is make the hole in the servo arm, just a tiny bit bigger so the pin goes through link, and through the servo arm, and then snuggly back into the other side of the link arm.

If your plastic head is getting sloppy... 1.) are the links with the holes.. on the balls or the shaft ? If they are on the shafts they will be sloppy.
The links with the holes the holes get bigger after awhile and make it sloppy.
Replace the balls with LOSBI 51 brass balls... and or replace all the links.

Don't get me wrong... but I think the problem is the learning to fly part...
You will have less darting around (easier) flying with a bigger helicopter... but that won't help you if you can't fly nose in or left to right in front of you... and your parts bill will be a lot higher.
Try desensitizing the servos as mentioned above.... see how that works out for you.
Also....
Try turning down the knob on the top left (PLT).
And turn the knob on the top right up a little (PIT).
This will make the helicopter less likely to jump off the ground and act more like a fixed pitch helicopter which I think also makes it easier to learn. Don't turn up the pitch too much because you do want the blades to spin up at a fast rate... too much pitch and the blades, motor, will bog down.

Best wishes. Flying these things ain't easy... but one day you will say...
"I can't believe I had so much trouble back then...."
