I have been an instructer for years and the LT 40 is my own personal favorite plane to knock around with. Mine has a bit of extra rudder and only 1/2 of the recomended dihedral. It has been thrashed by many students and be me too. It is on its third rebuild, and second overall color scheme. The funny thing is if you recover an old beat up bird and do it WELL it looks like a new plane. Mine has an OS 46 FX BTW.
