Suggested prop size for an Osprey

[Old School]

I am currently building a 41" Hobbyking Osprey mono and will need to decide on a suitable propellor to commence running (testing). By default the hull is fitted with a Turnigy T20 (56/98?) which will be set at 1280kv on 6s with two 6s 60C batteries in parallel. This will couple to a 3/16" drive shaft through a Speedmaster 1/4" stinger modified to run a 3/16" cable. The ESC will most likely be a Hifei Swordfish 200/220 amp model.

I currently have the following propellors to consider (balanced and sharpened) -

46.5mm 1.4 2 blade (brass)
48mm 1.4 2 blade (brass)
52mm 1.4 2 blade (brass)
52mm 1.4 3 blade (stainless)

Try both the 52mm props you have should get you in the low 50's
