After over 100 hours I finally got around to playing with Sensenich ground adjustable prop. Just grabbed the skinniest adjustment bolt and changed the prop from middle of road setting to climb. Went from 2750rpm on climb out to 2950. Climb angle is a lot more fun, slow but steep. Pulled over 3050rpm on level flight at 6000msl. Been pulling around 2850 max. Much slower airspeed and cylinder head temps quickly started to climb. Never would have believed the change it made. Spring winds are blowing here and may not get good flying conditions again for several weeks so serious testing will not happpen soon.
If anybody has done testing with UL and adjustable prop I would really enjoy hearing about results at various pitch settings.
No idea about that particular prop Ralph.
My plane came from the original owner/builder with a Catto three blade 68" x 36 pitch prop. Works good for me.
I use this little site to look into prop settings. http://culverprops.com/pitchselection.htm
Let us know how it goes. Really seems like it depends on if you're optimizing for cruise, or STOL.
