Good morning everyone !!!
This question goes to friends who are flying Continental O-200 engines equipped with ground adjustable propellers, such as Whirlwind and Sensenich:
Question 01) What static RPM are you applying ???
Question 02) What is the maximum RPM that you are receiving from the engine during the ascent ???
I’ve had a Continental C-90 on my 750 for over 10 years now, and the first 400 hrs I had the Whirlind 72” 2-blade GA prop. I now have a Catto 76X37 fixed pitch prop, but both perform fine. Regarding the WW prop, I recall using a 14.2° pitch setting which would give me around 2350-2380 static and around 2600 max power straight and level flight. The attached photo shows 2390 rpm nice cool air strsight & level flight approx. 90 mph airspeed from Oct. 2017, but this was with slats off which gains maybe 4 mph on my plane. I prefer to fly slats on and 90% of the time I do.
I would suggest you start at 14.2°, go fly, and adjust as needed for your 0-200
I'm running 2500 static, 2600 climbing, and keeping 2500 cruising with you at around 80/85mph. So, I believe I'm missing reality.
Thank you very much for the information.
Good flights !!!
