Glitch problem after crashed

[nic]

Hi all..

Since my last T-Rex crash, I seem to have a glitch problem.

The servos are ok before I increase throttle. Once I increase throttle, 10% of the time everything will start glitching... yup.. everything including the throtle.

At times, it is to such an extend that when I cut throttle... the throttle still glitch around 10%..

If I set my heli at throttle hold, I can play around with all the servos without any glitch... this only happens when the motor spool up.

What could possibly cause this? A damaged attena?

highly possible!!!!

resolder it with a new line when in doubt

Another possibility will be Crystal. I damage one Crystal before when I crash my Dragonfly.

Recently my Hornet II have glitches all over and intermittent. I suspect could be the crystal contact problem so I replace it with Futaba (Which I have it quite sometime back) and the problem gone for now.

Both crystal are Hitec.

check your esc wire to the receiver
shake the wire near the receiver end and see if there are any glitches
the wire could be lose

i second hornet. crystal shatter or contact problem. the vibration when at higher rpm may be disrupting the contact

Found the problem..

The attenna was worn out right at the base... (at the receiver box's outlet).

So.. the servos will go crazy when the attenna moves/shakes.
..

I cut the attenna down by 2 cm.. and use the rest of it.. seem to work fine. Not a worry since I am only flying within a 10m area.

Thanks for all your help.
