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 ???

Thanks !!!

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


Hi Jimmy!!!

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 !!!
