I plan on replacing my Hartzell HC-C2YR-1BFP/F7497-2 (Blended Airfoil for short) with an MTV-9-B/183-50a (3 blade) next weekend and was wondering what flight differences to expect.
1. Will it need quicker and more right rudder on take off?
2. Will it slow down quicker with throttle reduction?
3. If I get slow in the flair will my RV-8 sink more and need more throttle to keep it from bouncing?
4. The MT is about 5 lb lighter than the Hartzell, probably with less inertia. Will start up be any different?
5. Any other flight characteristics that might change? Especially thinks to look out for on first flight.
6. I have 232 hrs tach time/293 Hobbs on the Hartzell. The alternator belt looks good but would it be a good idea to replace it while the prop is off? I have a new belt just in case.
7. I'm not aerobatic or formation current yet but wonder how the MT might change these.
Here's the MT. It will probably look better on the plane:
I expect better take off and climb performance but loss of a few knots in cruise. Time will tell.
