I can understand those who say the basic run of the mill trainer will become boring to a natural student after a little time, but there are several avenues to take to make that trainer bite a bit harder! Convert that LT-40 to a taildragger, increase the throws a little, put on an Evo .46nt with an 11x6 prop, take out a little of the wing incidence, and it is ANYTHING but boring!! I've never even flown my LT-40 in it's stock, out of the box configuration!
