    At 50Kg you may want to look at some kind of counter-balance.

    Do not need gas strut. Any motor will be OK. For more smooth motion, a small lead or small motor with gearbox will be better.

    I'd consider a spring to take up some of the weight, though. By not having the servo constantly fighting that weight, it'll use less power and run cooler.
