Just got off the phone with Tony, THE manager at HiTec. I had one of their 90 oz torque servos in my U-Can-Do 3D .46. The rudder servo stripped in the air! Tony absolutely refused to send another servo, oh, yes, would repair the servo for a fee, plus I would have to pay shipping both ways! The cost would total about $21 for a $25 servo!! Tony pointed out, and I saw is with my own eyes, that in the fine print of the warranty, there is NO WARRANTY on gears! Buyer Beware! You strip it in the air, even if it is the right servo in the right plane, doing the right job, your problem!! I have used HiTec servos for over 10 years now, and I have never had this problem, but I did not get a warm fuzzy feeling talking to HiTec when their response is, not our problem!! I was hoping that the company behind the product would be more supportive and helpful in this situation.
