Ok a few things.... If thats the G2 raptor that you have you need to chage the GYRO.......sounds like you crashed and bent the tail......those Gyro's do not hold up well with crashes......get the Detrum GY92 I think...its the smaller Detrum Gyro......also check your servo mounting for the rite distance from tail.. then also check the tail servo horn...where the tail rod connects...make sure you have proper hole.......there are a lot of factors involved......chech for range of servo motion.......it may be to great... I would still change the GYRO......Xheli has the DETRUM Gyro for around 12.00 dollars......very nice GYRO I use then on all my HELI'S
