I had a tower voyager also and it was a great plane for the price. I had a 46 xls magnum which was very good power for the plane, but a 40 la would be very limited on power. The tower voyager is not a trainer and need some power. Well I crashed mine because I ran low on batteries and I regret that I didn't charge them 5 hours more.
By the way, the tower voyager was my next step from an Aerobird and I could handle it very well without help. It flies like an Avistar.
