Gyro won't hold tail after massive overspeed?

[jmillett]

Hello guys!

I am hoping you can help me, I have a Raptor 50 with about 10 gallons of fuel through it in the past couple of months. I recently lost the throtle arm during flight and the engine(TT50H) went full open for at least 5 to 7 minutes before it destroyed itself.

I have since replaced the egine with a OS 50 Hyper which runs very smooth. My problem is that now the tail of the heli slowly rotates and the gyro does not seem to fully conteract the troque.

I am using a Futaba 401 gyro and 9254 servo combo that has always been rock solid. Now when I try to increase the sensitivity to stop the tail I get wag before the tail drift stops?

I did notice that after the nasty overspeed incident that the vibration must have rotated my delay adjustment on the Gyro to 100% . I returned this to 0% as recomended which helped but not totally!

Also I now notice that as soon as I just touch the Adjustment pots on the the Gyro the tail jitters? Is it possible that the overspeed vibrations have killed my Gyro, or is it something else??


Your help would be greatly appreciated.

Thanks
John
