E-flite PT-19 450 ARF flaws need help
E-flite PT-19 450 ARF I have this plane and I found that the covering is kind of loose ,even after reheating it to tighten it ,it became loose again , and I had to add some nose weight to get the cg right , and for some reason ,this plane wont wright itself for all the dihedral it has , they discontinued it ,do you think it had some design flaws in it ?
