600E Pro Flybar Version 780 Gyro Gain Issues

[rayboulds]

Hi,

After waiting months for my ESC, I have finally finished the build and went out and did a test flight this weekend. Everything appears spot on apart from a slow wagging left & right on the tail. I have tried setting gain from 20% upto 50% and no luck. My 450 holds solid at 38%.

What Gain % are people running on the 780 Gyro with a DX8 ?
I have noticed that the tail blade grips have some play would this be causing my issue ?

Thanks for your advice.

What head speed/ throttle % are you running?

[tyjudd]

Mine did that and it was the tail grips.

[rayboulds]

70% Throttle

[rayboulds]

How did you solve the tail grip issue ?

[rayboulds]

Tyjudd, Are you using the 780 Gyro ? if so, What gain setting are you running on the DX8 ?

Cheers

70% Throttle

Thats a bit low for the 600efl pro unless you changed the tail drive gearing to the older ratio ones.
Think you need to running at least 85% to get good tail authority with the std gearing.
I have id1 at 85% and Id2 95% on the fbl version.

I am flying the flybar version with align 780 gyro and the wagging is happening when hovering.
I will try increase the throttle and see what happens.

You will probably find there is binding in your tail grips,we have seen this on Aligns many times.

I bet you were in Heading Hold mode and if you put the gyro in rate mode it will stop this slow wag.

I cant remember what the setting were know as i have gone FBL but my grips were loose and flapping about abit to much but after rebuilding the tail it was fine.

I do not believe I have any binding. I was in heading hold but I have never had any trouble before

Not sure what to do about the grips. I will try rebuilding, I might see if I can put a washer on the tail rotor hub to reduce the play.

Binding as in not smooth,not on the limit,is what chris is saying...disconnect the control rod link from the tail and manually control the slider,it needs to be silky smooth..

Any loctite in the small brass bushes will cause it,or over tighteng of the tiny philips screws.

I disconnected the control rod and the tail is as smooth as silk and so is the servo and control rod movement.

Not sure what to do next, might try tyjudd idea and reassemble the tail control hub to reduce/remove the play in the blade grips.

I quick question about the control rod, the metal cover on the control rod is that might to be tight within the tail control guide ?

Are you saying it is tight?
