Hey guys... sorry to hear about the issue. To have two servos fail simultaneously in the flaps to me would indicate that there was a slight load on the servos when they were up. It is always good to check the current in the position with an ammeter to make sure they are not drawing too much current. You can also set overload protection with any one of the Hitec servo programmers which will throttle the servo power back as needed to attempt to keep it from burning up. I usually set this to 20%These are extremely popular servos and there has been no indication that there is any issues with them. It seems these situations may be application/installation related. That's not to say that servos can't fail as they can, just as any electronic item can, but it would be very odd to lose two at once.

Hitec servos carry a two year warranty so if there is an issue, send them in and we will repair or replace them at no charge.http://hitecrcd.com/support/warranty-service
