n5c wags need help
N5c with os 55 hz limited hitori pipe rail blades cgy 750 sbe-1 spektrum to sbus align mg dg servos

so i tuned heli in and was flying great 2 weeks ago. I took it out again last weekend and flew great until the last flight. At the end of flight i got a tail wag. I didnt do any adjustments until i flew it this past sat. I changed gain values helped a little by could barely tell a difference. New glow plug, tightened belt, moved ball and link one hole closer to center servo. Checked all mechanical 90s everything checked out as normal. Ive had 2 other guys look too and they checked the same. Went through 750 and reset up the tail. Still wags and bounces at the end of a piro. Anyone have any suggestions.

Check the tail push rod to being free. Check the tail, it must be smooth and free with no binding. Check that there is no excessive sloop in the tail slider.

How is the engine tuning?

Also this is in the wrong forum. You might have a little trouble not seeing your post.

Why did you change the plug? Is the motor surging?

Here is the thread for nitro.
https://rc.runryder.com/f107p1/

Is the tail hub bent? Do the blades look good? What brand of tail blades. Are they on the right way? Going in the right direction? Just some stuff to think about.

As mentioned. Is the tail linkage very free and smooth. Disconnect the tail pushrod from the rear bellcrank. The pitch slider should pretty much move without effort. Did you size the tail pitch links? Governor working correctly? Lower the Gov gain and see if that helps?
Other things to check.

Cheers

Just wanted to chime in here. I had to increase my tail gain to stop the wag. Just a thought. My gain on vbar is 90 percent before it stopped .

In normal mode non heading hold does the tail drift at all? Even at 90* I assumed I was okay but had a drift... I had a lot of similar issues and had to adjust 100% of the drift out,

Try 3D mode stock deg / sec in the cgy, delay mode constant.
