Q8: Synchronise for noise abatement??
Light piston twin, rotate, positive rate of climb, undercarriage up.
Maybe, say, 200 feet agl....little tweak with one finger on a prop lever - synchronise props for noise quieter operation - noise abatement for both passengers and ground dwellers (possible letter writing Nimby's).
...or leave props fully forward until 500 feet - or whatever.
Comments for and against??
