Comments: We purchased 8 Hitec servos and within 2 months
two become malfunction. While we were using many become malfunction and gave jitters unexpectedly. Recently I saw last servo jitter when I check inside servo metal wheels has damaged .
really poor quality motors , not recommended to purchase
