I don't exactly have a jet, although i will not to far away but i had a servo failure of a brand new JR servo in my WM Dago Red p51 on its maiden and it scared the crap outa me thinkin i'd lost a brand new plane, engine and gear... luckily it landed perfectly as the elevator servo that failed failed with about 5% up elevator! Replaced that with another brand newy, and some how freakishly the same elevator servo stripped all four mount bolts and the servo was floating... miraculously it landed fine again... so two flights in a row, two '1-in-a-thousand' incidents on the same servo on the first two flights... it aint a good feeling thats all i know... if it was a Jet, i'd be crying for weeks at even the thought of failure
