Great plane, I have a GMS 32 on Mine. Its so light it will almost thermal.
The only things I don't like about it are inverted requires full down elevator and unless the landing is perfect it doesn't want to stay on the ground. Rolls are slow and require down elevator in the middle or nose up in the beginning.
I don't have any expierience with any other trainer so I can't compare it. It was my 6th plane -still loved it, If anything happens to this one I will definately get another.
I have had mine next to a 60 size Tower trainer there isn't much difference in the size.
