I know it's not about Gliders, but same principle, when I got my 1st Wallaby 9 months old and pregnant, she was wild and my fencing had not been finished but kept her in 8x6 shed.
When I 1st got in, she shot from wall to wall and floor to ceiling in turns, but only once till I was in and she settled...I sat on floor in centre very still for about 5 min...then talked to her... and offered her a buscuit, which she took out of my hand after a while and a few days later she let me stroke her, and each time after I entered, she accepted me and was begging for THAT buiscuit...lol
I did this several times a day, 3 weeks later, anyone could touch her, she followed me like a dog. I had often let her out and she sat outside my home waiting for me to come out.
I think I'd rather tame another Wallaby lol

So a fav. tit-bit will do the trick with Gliders, but needs lots of love and patience, above all common sense.
