Product Description
This is the third version of my 1/20th scale Schnellboot "Left Hand" propeller, the first version wasn't quite the right shape, the second one was a little long and both versions had slightly undersized holes and dog drive slots when made in brass. These are designed to take a 4mm or 5/32" dog drive on the front end and the two wing props need a "spike" tail to hold the propellers on the shaft, these are available as either a screw on spike for an M4 threaded drive shaft or as a spike with a grubscrew in the side for an unthreaded 4mm or 5/32" (3.96875mm) shaft. This propeller, like the original has a pitch of 2 and is overall 50mm (2") diameter, therefore every rotation theoretically travels 100mm (4"). The original Schnellboot had two left hand and one right hand propellers (on the starboard side (right side looking from rear).
