RE: They used to know how to make props!
Propeller choice was very limited in the 50s and 60s and all
control line speed contests that I attended were won by those
wierd props that you found. Tony Grish did indeed have a way
with aerodynamics.A modified version of his prop won every
speed contest and many freeflight meets as well for quite a while.
At least in my world

Ralph78, man that's a hard call. I probably would just admire them
for a while and then compare them to more modern props. I do not
remember what RPM was realized by a Dooling .61 or a .29 on 60%
with 7 and 9 inch props but it is safe to say that the rs were scary in
the day. I never threw a blade. TYL. Ralph

I still miss the Top Flite Super M props. I use Graupner these days; a lot of people slam 'em for being heavy, but every one I've used (on multiple displacements) pulls like a mule.
