Hello and sorry again for my multiple questions.
The good news is I am at the end of the ordering process. So no more questions... ;-)
I ordered an IO-320 160 HP new from Van's.
I will install a fixed pitch. I will go with a Catto.
I will operate occasionaly from relative short grass strips (1400'), mainly from longer strips and airport, I would like to have a lot of fun with it (i.e.: acro), I will mount a full Raven. I have inverted fuel system. I am planning to build it as light as possibile (Dynon SkyView, one VHF, one GPS, no lighting, Aerovoltz battery, minimal upholstery). I will 99% fly solo and for sunday short runs.
I received an email from Craig Catto and he suggested me to go with a 69 pitch propeller. 3 or 2 blade my choice. He stated that with a 3 blade 67diameter and 69 pitch I will have 2.300 static and 2.750 on top 193 mph.
I am not familiar with fixed pitch propellers and maybe I do not have the big picture. Why should I go with a 3 blade or rather opt for a 2 blade? Better brake on descent while doing acro? Much smoother? Better pull on take-off?
Will a 69 pitch give me enough cruise speed?
Will rather a 70 pitch ruin my take-off run?
Thanks.
Camillo
