I'm not sure how you define an expert, but I'm definitely not one! But I digress....


Our mutual friend Randall K wanted to get into indoor rubber and had many excellent questions. My daughter also wants to get started. In doing some research for them it piqued my interest in building one. Good for banging around the local gym and not worrying about breaking anything. Also, helps me help them. AND, all the propeller data was published for ALL to see on Hippocket. With the rules the way they are, I don't see where any particular design will be better than any other. Just good clean fun!

I wonder what the proposers of the P-18 event think about all the expert interest? Probably not happy about it IMHO.

Ray,
                          

                    
              
I had posted this info on Hippocket a few days ago. Pitch measured on A to Z gauge at 2" radius. Pictures are on that site:
                                  

                        
                    Williams Bros. 5.5" 2.57g 5.9"P
                  Peck 6" 1.81g 3.8"P
                  Kaysun 6" 2.72g 6.1"P
                  Tern Aero 6" 2.95g 6.1"P
                  OS-150 5.75" 1.84g 5.3"P
Pitsco 6" 2.75g 5.1"P Measured by Bill on Hippocket
                    Unknown(red) 5.5" 1.60g 6.7"P Blade shape like old Sleek Streak
                    Unknown(red) 5.375" 1.79g 9.1"P Blade shape like old Sleek Streak

                      I actually have multiples of most of these except the last one. Some aren't useable due to unequal pitch between the blades.

                        The last prop has a counterbore molded into the front and a "1" molded on the back of one of the blades. Wish I knew where this came from. Anyone have any ideas???

I'm glad to here some responses to my post. How about you owners of Pitsco and other props weighing some (without shafts or hangers) and posting the results. That will be useful for preliminary evaluation of various props.
