Logesh M, the prop I used was an APC 6x5 propeller. Depending on motor size and KV used, different propeller size and pitch can also be used. Example, if you use a 2200kv motor, a 6x4 prop can be used. The Prop size is also listed in the plan set (see below picture).
The FF-Viper-50mm plans have USA Letter size tiled pages. The Plans also include a NON-Tiled sheet at the very end of the plan set. Full size plan is USA Architectural size 24x36 inches, which is close to A1 size.
