I still have my DTF Otto, built using white Gorilla Glue, hanging on my bedroom wall. It was such a fun biplane to fly. I added ailerons and lowered the dihedral by half if I remember correctly.
LOS was due to a poor radio selection and the "Dutch Roll" was exacerbated by too much rudder throw.
It was still great fun though and I learned a lot from it!
have fun!
