REFLECTOR: Does anybody know of a Std Velocity with a IO-540?

[Jack Prock]

I just picked up my Catto prop a couple months ago. I will be flying an XL with an IO540. This prop looks 
very different from others he has built in the past and he says that the new design should help
with the acceleration and low end torque.... we will see. 

I went with a fixed pitch for budgetary reasons and I’m guessing eventually I will also move over to a CS prop.

Hopefully, I will start flying by the end of the year, so I will give a performance report about it then.

Cato makes great props, but it seems that many folks with the 540 eventually answer the siren call for a CS prop.  We flew ours (XL) with the Catto for a couple of years, and it performed well, but we got tired of worrying about flying our more portly friends on hot summer days.  Climb was good, as was top speed, but the acceleration is night and day.  Sometimes that's a big deal, sometimes not.  Just something to think about.

  this would be a good overall performer.   Any comments?
