REFLECTOR: 2 bladed prop

[Scott Derrick]

the problem is that the total blade length is proportional to horse 
power. With a 180 HP engine you might be able to get by with a two 
bladed prop...

We just don't have the clearance being a pusher, departing and landing 
puts the prop very close to the ground.

a conventional gear, tractor style airplane can handle the longest prop...

     The only security of all is in a free press. The force of public 
opinion cannot be resisted when permitted freely to be expressed. The 
agitation it produces must be submitted to. It is necessary, to keep the 
waters pure.
