Trex 450 Tail shaking please any suggestions?

Trex 450 for some reason i think it might be GY401 causing this all shafts are straight everything double checked with blade tracking and balance. Tail belt bla bla bla.. so why is it when i get to the point where its just about to take off starting to twitch side to side. Same heppens in mid air fliys normaly for 10 sec and then shakes for 5 and then stops again.

Would the belt be too tight? OR

Would the gyro sensitivity be too high?

i dont think its the belt, as before i had it slightly loose and now tighten acording to the manual and still same problem, So ive ordered a new ESC as see that may cause this problem. shuld arrive this week.

you are in HH mode when the gyro light is on, switch it to rate mode..

I had the same problem, my pitch where to high. Try max 7'

[emthreekia]

looks like gyro sensitivity to me. i have mine set around 70% on a dx7.

Your looks to be too high. does it do the same airbourne with no tail input?

hope u figured it out by now,somtimes th smallest things can cause u problems,..... plate where th gyro sets can be just loose enough,..gyro gains on th tx too high...dirt on th tail shaft causing pitch slider to bind....tail bades not centered wheflights,peace.n setting 90deg......u just never know...good luck ,and safe flights,peace.

I've seen much worse on mine at times, even whilst flying. Combination of gyro gain and rigging (i.e. moving the link to a lower hole). Others have already said all this, just confirming it. If you have enough channels, putting the gyro gain on a radio channel is a really good idea. You can tweak the gain WHILE the thing is running and shaking, to immediately see the effects.

@cfreire31 move yourtail servo ball link on the servo horn as far to the center as possible , it solved it for me.

Hello friend, I have the same problem!

I've change the Esc, receiver, tail servo and problem still there. Can be the motor, gyro gy401?

Can you help me? How you fix the problem?

Help me please?

Thanks.
