The Kjeller Aircraft Factory FF.5 was a reconnaissance biplane in two variants, The T.1 was based on R.A.F BE.2e, and the second was T.1B, which based on Avro-504.
The FF.5 was intended to replace F.F.1 and F.F.2 trainers in Norway. The one F.F.5/T.1 built, in 1918, was unsuccessful.
NB: T.1B and T.1C were unrelated Avro 504-based designs
