i've been experimenting with a catto 3 bladed prop. built in 2009,is made for rv4 160 hp i have 160 hp, in the rv4, engine is fine,good compressions.
at 4000 ft. 2500 rpms my speed is only 165 mph. when i advance the throttle i can reach 3000 rpm's but it feels like the prop is not grabbing and doing around 190 mph,
initial climb out at 100 mph getting 1900 fpm but after 4000 ft it drops down to 1100 fpm.
is this common for a 3 blades prop?
i'm a little disappointed in the performance any comments?
thanks
