RE: Low wing trainer?
I see that you are leaning towards Spacewalker II. I am in similar situation. I like the way Spacewalker flys on sim. You can purchase from Horizon Hobby. It is made by Seagull & sells for $119.
I was considering this plane for its looks but I have realized that my second plane has to be sturdy enough to take abuse. I am not sure if Spacewalker is sturdy ennough for anticipated hard landings !!!!!!!!!!
I am now considering Sig 4* 60 but will build cowl to make it look pretty.......
