I am trying to use the carbon pushrod but I am finding that when lined up straight it the ball link end is at the center line of the servo wheel. If I try to go to either the top or bottom of the wheel to hook up the pushrod to the servo it puts a sizeable bow in it and thus it binds.
I know I have the then wire push rod but I would really like to use the carbon one -
Anyone have any suggestions

I tried that - almost seems like the guide it too "tall"

How much throw do you have on the servo wheel? Maybe you can take the servo ball link in a bit or out a bit.

Mine is the same way. The pushrod guide is too long for the application. U need to remove the guide & chance running without it or replace it with one with the proper length. Drev.

Honestly, I don't even use one on my 600. Although I have it on my 550 & 700 and i think thats b/c the tail servo is located in the rear of the main frame.

Even the inner most hole in the servo wheel puts a nice bow in it.... maybe I will try with out the guide and see how it feels

Hi, I just joined the forum. I'm a total newbie but found a good deal on a 600 and have been spending all my spare time on it. I've measured the center to center distance of the metal push rod guides and the C-C distance of the CF push rod guides and there's about 3/16" difference between them. The C-C for the CF guides is longer and because the shaft is so rigid you can't bend it enough to line up the ball links with the servo horn or the control arm. My push-rod has the two metal guide sleeves and the guides won't even clamp down tight enough to grip them where they won't slide fore and aft. This weekend I plan to heat one of the end-caps and try to slip it off, remove both of the metal sleeves and re-epoxy the cap back onto the rod. Since this thing is so rigid, my plan is to run this thing without any guides at all. The only concern would be if one of the ball links were to shake itself off of either of the balls my bird would be toast. Have any of you guys tried this? How did it work for you? Thanks

I run mine with no guides. If either of the balls can pop off easily replace them and keep an eye on them. I also get no vibs on the guide.

Thanks Valkman. I'm not sure what you mean when you say you get no vibs on the guide. Sorry, I don't mean to sound dumb.

You might want to watch this video before making your decision.
I was running a CF tail rod on my 600 with ball links that were slightly too large. From personal experience, you don't want the rod to come off in flight! You will need a new pair of shorts!

PS: Oversized rod ends were from a QuickUK set. It works just check the fit before flying. Don't try it until you have a good fit between the ball and the rodends. I changed out the rodends to a standard size and haven't had a problem since. Also added a support though.

I forgot to mention my rod is a home made one. I think it is 8mm. The one in that video looks like 3mm! As I said, keep an eye on the links and make sure they are tight. Mine are nearly impossible to pop of by hand. If in doupt, use the guides to be safe.

Think I'll go ahead with the carbon fiber rod. It's 3mm but it's extremely rigid which makes me think it's probably solid. There's no whip in it at all when I hold it by the ends and shake it. I just don't like the idea of having to wedge a piece of a tye-wrap under the stock metal rod guides to get them to stay in place. What's up with that anyway?
