So there's supposed to be a spacer there pushing it down?

no there is supposed to be more space between them so the swash doesn't bind against the hub. In essence if the swash touches the hub you will loose full movement of the swash and loose its ability to guide the heli in anything more than a mild hover, pretty much what you are describing. Here is a very old pic but you should get the drift.

I've tried moving the control rods to the farthest end of the servo arms and still not much luck. I think he put some after market parts on it, can you tell by the photos if something was not setup right? Thanks for the help.








Here is a link to some pictures of what I did to prevent the lower end of the lower rotor hub from binding on the top of the swashplate. Use a dremel and trim off around a 1/8" so you have clearance between the two. When I flew outdoors I had the pushrods in the third hole from center of the servo horn. It's all I needed, and indoors I still fly with the pushrod in the second hole. The further out one goes the more chance of binding.

Three things I can recommend:

1. Get rid of the current boom with the aluminum mount and get a Boomtown model 4 boom. Your current boom is going to limit your forward authority by moving your center of gravity further rearward.

2. Get yourself a shorter flybar. The flybar at stock length limits cyclic authority dramatically. If you can't find one already modified shorter you can buy a Dynam Vortex flybar and use the adjustable weights off it with your flybar. Optimal flybar length is between 4.25" and 4.5". Part number VTX-002 will fit your CX2, part number VTX3-002 WILL NOT. The weights will work off of the newer flybar, but the center hub won't fit, so you'll have to use the new weights on your stock flybar.

3. Get yourself an extended shaft. Once you shorten you flybar your chances of blade strike are going to dramatically increase. You'll need an extended shaft at least 2 cm longer than stock.

A note on item #2, the Dynam flybar. I have one of those and BP HObbies doesn't carry them anymore, nor does HeliDirect. It also comes with a fixed flybar link.

The fixed link isn't an issue. You just transfer the linkage from your original flybar to the new one.

As far as being sold you can still find them, just have to google a bit.

Is just the picture or is the swash awefully tight to the lower hub aswell? possibly limiting movement or even binding slightly

There is a cool tool at the top of every page. It's called "Thread Tools." Click that and scroll down to "Show Attachments in This Thread." You will see countless pictures of the swash. Not to mention some other "very" interesting pictures

WHOA...OTTO, hold on a moment I was just trying to be helpful so you could find other pics that other members submitted so it would help you find the problem. BTW, yes, the lower rotor being too close to the swash will bind the swash as Kodak Jack pointed out when he told you to scroll up to post#6258. I assumed you were looking for more evidence (IE: pics).

Not even seasoned members know about the tools at the top of every page. Sorry if you feel I rubbed you the wrong way but, I'm sure you interpreted my post "completely" the wrong way.

Mike,

It's sad some people are so easily offended. I appreciate the tip. I've been on RCGroups for over a year and did not realize that option was there. Hopefully Ottoflys will discover a kinder heart one day. Life's too short.
