i agree with others that the TT will NOT fix your prob.
i had the GY780 on my 500ESP and it always had issues with holding the tail ROCK solid in punch outs, but it will work well for learning.
Pete's idea of plugging the tail servo direct to the Rx is great for getting the servo centered, you can also turn your gyro gain in the Tx to '0' and it should do about the same (although I've never personally tried it).
once you have the servo centered make sure you install the ball at the closest position to the boom on the servo arm. (10-12mm)
after reconnecting the gyro and your going thought the set-up, make sure the gyro direction is sensing the correct direction. if you move the tail to the right, the trailing edge of the tail blades should also move to the right, and vice-versa to the left. if your heli spins out of control on spool-up, it's backwards.

i found that the 780 likes about 72-75 in gain for HH. (DX7)

upgrading to a better gyro or FBL will fix alot of your issues. i suggest sticking with FB until you learn how to fly and correct before moving to FBL.

hope i've helped...

My crashes are cooler than your flying! ;^)

Pete, Stan, and Funknrock that is go info but I'm not tracking Pete with what you said about holding tail and go left right and that will tell you. Well it probably would but it better slap me in the face or down to a second grade Heli level cause I'm not tracking now. After all of that you just gave me a headache. Just kidding.

I agree that wag is not good at all, gives me flashbacks of the Blade SR that's in a pile at the house. I do believe that I'm going to buy a new Futaba Gyro to match the tail servo just for the hell of it. I'm going to change out dampers tonight and recheck mechanical tail stuff and then buy the gyro. Again guys I do appreciate all the lessons that you have given me and I will try my best to understand, adapt and overcome this Heli flying. It will not take me, Uncle Sam couldn't do it so Trex won't either.

Thanks, Gary

Hold On!!!!!
I spotted anther post about this same subject and they had some other ideas..
My friend was having the same issues as you... he had also changed out the gyros and did not cure it... he took the tail assembly off his other 500 and installed it on the one with the problem and it went away, so he is sure now that it is something wrong in the tail rotor case, so he is going to investigate that and will let me know what he finds... so if you haven't ordered your new gyro yet, maybe you will want to hold on.. sounds as if an easier cure may be coming soon!!!!

New Info, Take A Look

Looks as if Peter may have found the problem..

Also sounds like quite a few people have had the same problems with the 500.... good to know about....

Sounds like a Tx issue?
Based on what I've read so far, I'm thinking it's more of a Tx programming issue than anything. I've programmed a few DX6i's and a few DX7's and I've have similar issues almost always with them with various heli's new and old. Mechanically, the helis were setup well and the programming for the gyros was correct, but no matter how many times I redid the settings, the same problems kept occuring. As soon as I tested the same setups on a better Tx like the 9503 or 9303, the problems went away.

The DX6 and DX7 have never been my favorite Tx's to program, mainly due to the poor menu navigation and abbreviated functions. As many heli's as I've set up (at least 15 since 2002), I've never been fully satisafied with the final product when these two Tx's are involved. The more advanced Tx's allow you to go a bit deeper into the programming while giving you a better visual of what you are trying to do. Since getting away from the low-end DX and low-end Futaba line, I can program a new model from the ground up in minutes with no need to fight with settings and little need for trimming either.

I'm not saying go out and buy a $700 Tx right now, but if you have a buddy with a more advanced, I'd see if he'd let you program your model into his system. I'm almost completely positive that you'll find marked improvment in your tail performance without the need for a new gyro or tails parts. Most likely, you'll see improvement all around. It's definately worth a shot given that fact that you seem to be chasing a phantom problem at this point. It'll save you alot of time, money, and frustration and it should only take about 10 minutes to program and bind your model up. If it does work, then at least you'll know what your problem is and can save some scratch for a better Tx down the road. You can probably find a used 9303 or 9503 for around $250 here on RR or ebay. It's a great Tx that's reliable, easy to program and is difficult to out-grow. Good luck and happy/safe flying

Gary,

Richard1 indicated he replaced the plastic tail rotors with carbon fiber and that solved the problem.

I did replace the stock tail fins with some orange KDD fins. I'm heading for the Birmingham Fly-in tomorrow so hope to have someone to take a look at it ans tell me that I'm seeing things and that it's good to go. Thanks.

Keep us posted and have a great time.

Interesting about the radios. You would think that piece of information would be all over the forums. Seems isolated.

^ +1 I've been programing and 6's 7's for some time I've never run across that issue.The 780/500 combo is plagued by wag issues now that's all over the net. Some times changing the delay works, but not always.

Very little attention has been put into using a carbon fiber tail rod

Would a carbon fiber push rod make that big of a difference?

Have you tried a different delay setting?
Worked the other day on a 550 I was working on.

Lean Manufacturing, in theory, you learn to indentify mechanical vs. electrical. sit down and have 2 columns, electrical and mechanical. list them out. if one doesn't work, cross it off your list. mechanical would be the first one to identify.

if you have the linkeage ball on your servo wheel or arm at 90, and the stock rod (who's to say this rod is exactly straight)has to go thru the 2 stock tail control guides to the tail rotor control rod's linkeage ball.

and look at the way Align's install of the stock tail control guides: zip ties?

Maybe removing the guides might help. You can't replace everything and have no results. It's costly.

Mike I don't know how to change the "delay" setting. If you could walk me through the procedures for my Dx6i I could try.

Nelig, I can only say guys at the field say it is mechanically setup so will the guys at the B-ham fly in take a look at it tomorrow when I get there.

Will reply back here with what they say/do to fix the issue. I'm Turkey hunting first thing tomorrow and hope to roll into B-ham after lunch. Thanks for the hand guys.

Watch at YouTube

About the 9 minute mark. I figured a video is worth a thousand words.

There is a small Velcro stap but I used it on the ESC. I have I mounts on right side of Heli. One guy suggested to move to under batt tray to help on CG. My batt now hangs off front edge by 1 1/2 inches.

FWIW...

At 9:04, narrator states small helis on red, bigger on green.

At 10:14 the opposite

Either way it shows how to figure it out...good video.
