'I brought my "new" PT26 back from Hayward, CA to its new Home at 7B3, Hampton, NH and find that the 2600 foot strip with trees at the end is bit tight on takeoff with what apparently is a cruise prop. I'm planning to install a "new" 220 Aeromatic prop when Mark Denest does the annual October. Some questions:
1. Has anyone got a PT19 or PT26 with the Aeromatic on a 200 HP ranger? What change in performance numbers did you get?
2. Is this prop on the Type Certificate, or does one have to get an STC?
3. What is the appropriate red line RPM for initial take off on the Ranger engine?
4. Any other comments, suggestions?
Thanks,
Jeff Clark'

Re: Aeromatic Prop, 200 HP redline on PT26
'I do and others have had them. It can be, assuming FAA cooperation, be
approved via Field Approval.
1. I can give you precise before/after numbers as this airplane has had the
Aeromatic on it since I got it. Although, I flew a fixed wooden prop PT
before having this one. Which prop do you have now, 86R61?
In any case, on a standard-ish day, I'm getting 800-1000 fpm climb.
2. Field Approval
3. Redline for Ranger is 2450. The Aeromatic setup for a Ranger powered
F-24 is 2400RPM static. Actual will be a bit less as the static RPM is set
with the weights removed. I'm getting about 2350 intial.
4. There's a definite improvement in climb performance and some small
cruise increase. I'm getting between 105-110mph cruise at 1950 RPM.
