I am having such a blast with this thing..it is a .15 trainer from thunder tiger 4 u dot com , it has a .15 magnum and I have it dialed in pretty well....it flies like a stick full on, rolls axial either way...loops pretty tight, if you get disoriented just lower the speed and let loose of the sticks,,once it deadsticks (yes I ALWAYS purposely deadstick) it is a kittycat in the air, will catch a themal and glide for ever!!!....... the landing gear needs bending regularly but for $70 if you already have a .15-.20 engine...get one!!!..Rog
