While the Tiger 60 is a good flying plane it is heavier than the LT 40 and requires a 60 size engine, on the other hand the LT 40 has the same wingspan and a good 46 will power it nicely. My LT 40 will knife edge, roll and loop, hangs on the prop very good and then makes nice gentle landings so I guess what I am saying is that I would wait on the LT 40.
